Thank you so much for this educational video!!! By your multimeter test I needed a power supply board. Unfortunately the power supply board I needed wasn’t in stock on your website but I did find one on eBay and now my TV works again! No TV repairman costs at all since I was able to diagnose and fix myself. I’m in a debt of gratitude and will refer everyone possible to your website, videos, products...etc. Thanks!
I have a Toshiba 40e210u1had this problem....after watching your video i figured out that I did have the 5v standby on the power supply so I replaced the main board as suggested. The Tv is now working again, thanks shop jimmy!
Hi, I have a Phhillips model- 24PFL3603/F7 the only thing that turns on is the Optical cable light, any idea what it could be.I changed the board and all the same. Would appreciate any help, thanks.
My Vizio LCD sometimes won’t power on. If I unplug and plug it back in, it will work for a while. Occasionally, it’ll turn off by itself while I watch, and I can usually just turn it back on. Also, if I haven’t used it for a few days, it sometimes won’t turn on. Unplug/replug seems to fix it as I described above. Power board failing?
Hi Jim, thank you very much for your video. I have a Sony Bravia 60" kd-60x690e TV that is five years old today. It turned itself off, and will not turn back on. No lights, nothing. There was no surge. I removed the plug from the surge protector, and plugged it into the UPS, no change. I plugged it into the wall outlet, no change. I'm guessing a power supply board. When I watched your video, I could not tell where you grounded the other probe. Obviously, touching one probe to a connection, and leaving the other one dangling will not complete a circuit for electricity to flow. Where did you ground the other probe? Thanks.
Put the negative lead on the metal frame of your TV. You could stick your negative lead into a metal screw hole, making sure it makes a good connection.
Hello Jimmy. Great video! I have a lg 55ln510, #310rmhr7b601 that will show picture for 30 sec and then the screen goes black. The standby light is on when tv is plugged in. I have checked the standby signal from pwr supply to main brd and get the listed value of 3.5V but I get a 0 for the 12v and the 24v pins. The pins for the wire going from pwr supply to led (+/- +/-) started at approx 13v and quickly dropped to 0 when tv plugged in but not turned on. No visible blown capacitors. Any suggestions would be appreciated. Thanks!
I have an Element ELEFW328 curb orphan I took in. It's Main & PS boards are combined into 1 disappointing failure.I plugged it in standby light came on, hit the pwr button but no picture. Replacement board was only $12. I put it in and same results. I measured voltage at the power switch this time. The board that it came with had 0v. The replacement board put out 6.6 at the power switch. I'm corn-fused. What do those disparate voltages signify? It the power switch bad? I dressed as Uncle Fester last Halloween. I was going to wear the same costume, but say that I'm Rudy Giuliani. Do you think I can pull it off?
Hi Jim love the video troubleshooting ,I have a 40 inch pioneer plasma t.v it'll play for about a week than it goes out for about a week than it'll play again what could be the problem. Thank you
I bought the repair kit from you guys for the dps-162kp a power supply im wondering if you have a tutorial for testing and replacing each component in the kit.
hey, I have a power supply board with standby votlage. I shorted (using a tweezer) standby voltage to the power on pin to turn the tv on. then measured the unregulated 24v output and was only reading 1.4v. What could be the problem? I have a sony dps-162lp board
hi sir you i want to ask about a samsung tv le37c630k1w this tv has only remote control no power key but i have test the remote is ok if standby voltage is ok so in your opinion the problem is the mainboard ? its not needed to check the other voltages of the power supply ? the red light of standby is permanently light and it seems to be permanently steady it doesnt blink when i give power on from the remote control
I ordered a replacement power board for a TCL 55s401 (2 years old) because I had no backlights. Flashlight test confirmed there was a display. I installed the new board from ShopJimmy and I get no response at all; not even a standby light as I did with the old board. Thanks for any help.
I have Sharp 58Q733Ou and have replaced all 5 backlight strips. Using LED tester at wiring harness, will not light LED strips/ showing open circuit. Have replaced wiring harness but still shows open. All 5 strips light when tested individually. Not sure what is causing open circuit. Thanks
Hi there looking for some advice I have hitach tv that there is standby light but it flickers blue to red etc pressing the button the tv doesn't come on also my board doesn't show what pin is the standby volt. Do you have an email as I have photo of my board to see if you can help me
I have an LG 42LD690 TV. The power light shows in standby and goes to a wavering red light when on button is depressed. I have checked the power rails to the control board and they are ok. What outputs can one expect from the other outputs to the LED's? At the moment there is zilch. I have no picture.What and where do you think the problem area is? Grateful for any advice. The TV is only 5 years old.
Im looking for Proscan 117736 (RSAG7.820.1185) Power Supply Unit. I think it may only be a fuse can I get one of those while waiting for the power supply unit to get in stock?
I have standby 5 volts. I don't see any standby LED lit except LED on Network Port on Main. Power button does nothing. Main board is expensive. Is there any way to jumper or "trick" power supply to fire up the 12v side for further testing?
Hi, I have a 32" Phillips flat screen T.V. - Model no. 32PFL5522D / 05 . All was fine until a few days ago when I went to turn it on via the remote and nothing happened. The standby light has never come back on when plugging into the power supply. Have tried all the usual tricks by checking the fuse in the plug, plugging T.V. into another socket in another room - no joy. I am about to take off the back of the T.V. and go through the steps as advised on your youtube commentary. It makes sense to do what you advise about checking the standby voltage etc. Just thought I would post this prior to starting the checking procedure in case anyone has any other types of advice before I start. Thanking you in anticipation Ian J.
Hey Jimmy I have a plasma tv to fix. Lg plasma 50pt350ud is the model. The tv comes on and screen lights but no picture. It will not allow channel change or input change those buttons are unresponsive when pushed. It has no picture or sound.
I have a Sanyo model DP42D23 TV. It has a new P.S. board with all voltages good at the cable coming from the Main board. But it still doesn't come on .There is no standby light that is on. I went to the other end of the ribbon cable from the P.S. Board to the other rf/tuner/line out/in board and all the power and gnd's are good to that point. The board number on the board from the P.S. is NO: PCB J 0995 D1 W46/13. Other numbers on the board are Z7L 305A 49. Not sure if that helps. The power on/off button doesn't turn it on either. I do fine voltage across the power button when press. But still nothing happens from that point on. Do you think it's that board?
Hi. I have a Panasonic viera plasma TH-42PZ80U TV that will not power on. The red light next to the on button blinks ten times. I am guessing based on research googling the 10 lights, it is the power supply board etx2mm702mf-n. Is that right? Will replacing this board do the trick? Can the board be purchased thru you guys? Thanks, Dick and Norma
I have 5v on SB pin of PS but 11.6v where I should be getting 12v and 19v where I should be getting 24v...Any suggestions? PS or mainboard replacement? Thanks.
on my samsung un46z7100wf, would these instructions be the same, I have a red blinking light, and is there a difference between the ld and the UN, thanks tony
Jim I have a lg55- ug tv and it turned off on me because my outlets burned out with the tv was plugged in too now the tv don't turn on but I do see a red light when I plug it in . Idk with one to change first ? Pleas help
I had a problem with no video on a Vizio 50HG5. I did the flashlight test, and I saw images on the screen, so I ordered the "repair kit" that you offered. I replaced the main board, the power supply board, and all the other parts (I figured they would probably go out soon enough). I tried the TV, and now, not only do I not have any video, but I have no audio, and the TV won't come on, or respond with the remote or the buttons. I would like to return your "repair kit". How do I do this?
"Repair Kits" are something that came-about by "an expert" that got lucky and is opinionated, "more people will have this problem". Basically, a rip-off that I stay away from. The parts usually work out cheaper if you bought individually, anyway (from the same source, of course). I have never bought any "repair kit".
Hi Recently my LG 42 inch TV had backlight issue where video alone was not viable but that was too viable through flash light test. The service technician changed the back light LED after which the TV went to standby mode. Initially he replaced the main board still it was in standby. Then he changed the power supply board. Still same issue . He change TCON board even the issue persist. But finally when I asked him to change back all three to old board and when testing he was able to recieve supply to all boards. Which initially did not happen. Now with all old boards and backlight alone changed the TV still stays in stand by mode. I feel the technician is not having a sound knowledge on the issue and just like that he is saying the LED panel has to be changed. With your experience do you have any idea on this issue. Any small hint would be great full. Thank you.
Hello, I have a 12 month old vizio e48-c2 that will not power on (it began after a storm so, lightning is the primary suspect) I've removed the back panel and the components look like none I've seen on line. There is a small board at bottom center roughly 2x6 inches connected by a ribbon to a larger panel at 3 o'clock roughly 8x12 inches.. I can replace the the tv with a new one for $388. Can you tell me what the cost to repair might be? Is it possible that only a fuse is the culprit? Thank you. Kind regards, Billy Hardwick
Hello, I have a LG plasma tv model 50pj350 with sound but no image. I checked the power board and it is working, changed damaged mosfets on YSUS, caps read ok, so do resistors and diodes. Though the VY and VSC testing points shoud read -198V and 135V and I have no more than 60 volts on each. Any sugestion? I’ve tried to get the board diagram with no success. Thanks.
I am a repair tech with 25 years experience in the repair field with a big communication company in Jamaica.The problem I have is with a Samsung tv model number UN32F43AFXZP the fault is it will not power up when the power button is pressed. The power light come on then flash 5 times the off. I have taken out the power board inspected it the caps seem good then I checked all of them they are all good. I power up the board by it self all all voltages are present. Can you enlighten me as to what might be the fault and if it is the main board or power board where can I source these boards appreciated in advance
Follow up - I left it unplugged over night, and it is now working. Yeah! Any thoughts on why it would have done that? Is a major failure imminent? Thanks.
Hey there so a quick question I have a vizio m43-c1 so I have 5v on two of the pins as they should and 19v on all other pins that say +12v while the main board is connected however when I unplug the mainboard I lose the 5v on both pins on the power board is this normal? Thank you
Hi, I recently bought the AS19 T-Con Board Component Repair Kit off your site to fix my 46" samsung tv, model # LN46A550P3F and I am wondering if you have a video on how to use this repair kit?
hi jimmy. i have a sony aps-319 . what happen is when turn it on, it just shows sony on the screen and dark back without any image' what do you think that might be the problem?
I have a problem where my old board gives me power to light up led on front but he board I bought from shop jimmy doesn’t. Any thoughts? Am I missing something? Could I have gotten a bad board from you guys?
I have a rca mod #led42c45rqd ser # 2505-ld42c45d100735. The picture would shut off but the sound still worked shut it down and restart and it would work again. Now it starts flashes on for a couple of seconds and turns off. I looked at all the capaciitors and did not see any that looked bad. I only see two boards power supply and main boards. Where would the T-con board be located?
My VIZIO XVT553SV tv has standby power but does not turn on. It does have 5V standby so I replaced the main board per your instruction. This did not fix the problem. I then replaced the power board per your instructions and the tv still has standby power but does not turn on. What is left for me to check?
If I bought a control board just recently to find out that it is not my Version after replacing the power board I still cannot get the TV to power on mine is a Samsung UN50KU6300FXZA DA01 version and I believe the board I installed was a DF08, is there a difference on versions for the control board that you cannot see that would make the tv still not power on, the circuitry looks identical? Any help would be great could it be the P jog switch? or do I just need to order the proper control board DA01 version
Thanks for the great effort... I have a problem with the Samsung lcd-la32e420, and the problem is the following: When the power cable is connected to the power, the screen flashes and turns off immediately.. for the knowledge that the voltage measurements from the power board come out intact, especially 5 V.. Can you help me to solve this problem
I have a Vizio XVT553SV. The orange standby light comes on when plugged in but the TV will not turn on and the Vizio logo never turns white. I'm wondering if I have a power supply problem or something on the main board? I haven't taken off the back to see if there are any bad capacitors or anything burned or obvious but that will be my next step. Make sense?
+Ron Kirsch After taking off the back, everything appears normal on the power supply and the main board. No bulged capacitors or burned connections. Should I replace the main board?
I have a VIZIO L37HDTV10A. The power light is yellow on the front when it is off and turns on to green when I hit the power button but the screen does not light up. The problem started a week ago when it took longer for the screen to appear and now it will not appear at all. Haven't done anything yet to the set but will take the back off soon. any hints. The video I watched here advised to check the pins for power if it is labeled. Any further help?
Hi Marcel. You can use any cold ground pin on the power supply. You can even just touch the black to lead to the chassis in this case. Thanks for watching!
So to summarise - If you have 5 volts replace one board, if you don't have 5v replace the other. Not really 'troubleshooting' is it? I could have save y'all time on this video by just saying - "Replace both boards". This isn't really a 'troubleshooting" video. I was hoping for more in-depth analysis of the components on the board to track failure.
Hey bud. I have a vizio, the power does not want to come on sometimes, but when I unplug it and plug it back in it turns on, the other day I had to replace the fuse in the psb. I am wondering what is causing the fuse to blow and what is causing the the power cycle issue
What if I have no red standby light but have 5 volts on one of the terminals out to the main board? Bad main board or could the power switch section fail; the area where the red light is and the remote sensor.
If you can get the power supply identification number then you should be able to Google for it and purchase it. I had purchased a power supply board for my LG 60" Plasma television on eBay.
Hi Jimmy. I have a Panasonic TC-19LX50. The stand by light turns in green then makes seven red blinking then seven red blinking over and over and never turns on the screen. Pls advise.
I have a Dynex TV Model Number DX-40L261A12. The TV will power on after unplugging then plugging back in. It takes multiple times to do this. I do have the red indicator light that stays lit. Once the TV is on the picture is still excellent and everything works. I did try another power chord and that is not the issue. What do you think it could be?
Hi, I couldn’t get any reading on the voltage on the power supply but when I disconnected the cable going to the main board the backlight turned on, so does that mean my power supply board needs replacement or the main board?
Jimmy I have a Polaroid TLAC-02255 and I conect the power cable and the standby light torn on red , When I turn on the tv the red light changes to blue and tries to start the screen apears the logo polaroid after a few seconds turn of and change again to red. I check the power supply and have 2.9 volts when turn on changes to 5volts and after few seconds changes again to 2.9volts
Hello, I like your service and commitment to help / guide the community to repair the TV. I have a Sony TV - model KDL52XBR9. It has a blank screen - no video or audio or backlight. When I turn ON with Remote or Power button on the TV, just the Green Standby light comes on. If I disconnect and connect the wall plug, I hear some rely clicking and the backlight comes on for about 45 sec and backlight turns off by it self. Green standby light remains ON till I power OFF. Can you please help diagnose the issue? Thanks, Mohan
My 3yr old Vizio 50in went out so I bought a new board from you. Put it in and it fired right up, worked for a day, turned it off and couldn't get it to come back on. You were supposed to replace this board when one came in. I was told you get a lot of them and would notify me when one came in. No one ever notified me!! I'm still waiting.
Hi Jimmy, I have LG 70inch full HD Led tv, unfortunately it does not power on, I showed it to a tv mechanic and He said that display panel is not faulty. Replacing a display panel is too expensive, is there any other way or any alternate method.
I have a MITSUBISHI MODEL "WD-60638". When I turn the TV on nothing happens nor does the indication light come on. I tested the 5V test area on the power board and got a varying 1-2V reading. What would you suggest i look at next. Thank you for your time.
i have an emerson lf391em4-ds1 led tv and when i check the voltage on pins 20 to 23 of the power supply (on the schema it supose to be at 21volts) it read 11.5volts. what it could mean? thanks
i have a sharp tv and all it does it when i plug it in it turns on then it turns right back off nothing elce will work the remote/buttions on the tv plz help me
I have a lg plasma 60pm6700-ub. I believe it was stuck by lighting as the surge protector shows it is no longer protecting. Standby light will blink, when I try to turn on screen shows a faint gray color but never shows picture or sound and then appears to turn off. 5v standby pin (what I believe is the pin) one shows around 4 volts(first time using meter). Any help appreciated
Hi SJ as I was watching your video I ran a few test on my Hisense 50H7GB TV. I notice that when I press and hold down the power on the side of the TV the Hisense logo comes on and the TV picture comes on. The TV well stay on for about 2 minutes then it turns off. I have not opened it yet. Could this be a symptom of the power board?
I have a Samsung 55" LED Smart TV that during a recent storm made a loud crack sound and shut down. I have verified that all items in the surge protector still work, but the stand by light and power to the tv does not. If I follow your videos, what kind of price might I be looking at if one of my boards needs to be replaced? Before I invest all the time and money I would like an idea if I should simply buy a new tv and if so, what brand would you recommend?
Hi Shop Jimmy, Nice video, I have a LG, LED 55LW5700 tv, I checked all voltages all are goo except the "power on" voltage. It should be 24V and it is only 3.5V, All other voltages are good, does this mean my main board is bad?
I have a SamSung 59" D6900 Series 6 3D Full HD Plasma TV that was manufactured in 2011 that will turn itself on and off every few seconds and is stuck on PC input this first happened over a year ago when I was switching the input source from one source to another too quickly and I was reluctant to dispose of it because when it is on the picture is near perfect ! Very annoying problem if you have any suggestions what part I might need to replace (if I can find one for such an old TV) that would be very helpful thank you.
I replaced both my power supply and main board due to a lightning strike and still no power? I ordered my parts from you. i got them today. I decided just to replace both since i did not see any damage to my boards. I do not have a tester with me right now to test the volts. what could be the problem
OK I replaced the power supply and the main board and still will not power on???? I have 3.3 standby volts on the ps. Philips 47pfl5704D/F7 any suggestions now?? Please and Thank you
I have a 60in Sony mod# KDL60EX500 with a black screen. Took the back cover off and no back lights. Used the flashlight test and nothing. I'm sure the sound was down when it went ko as I was using a sound bar. The only way to get power is to plug and unplug from the wall outlet. When plugged in; the green light is on but nothing works. There is no red light ever. When plugged in; sometimes the little square black unit just below the coaxial connection at the main board glows red. Sorry for my rambling. What do you think is wrong and what can I buy to fix? Thanks

There was no surge. I removed the plug from the surge protector, and plugged it into the UPS, no change. I plugged it into the wall outlet, no change. I'm guessing a power supply board.
When I watched your video, I could not tell where you grounded the other probe. Obviously, touching one probe to a connection, and leaving the other one dangling will not complete a circuit for electricity to flow. Where did you ground the other probe?
Thanks.
Same question, i really wish he wouldve shown it randomly. Or purposefully.
I am so glad found your channel
Dumb question... where do I put the negative lead ? Any metal surface? Or is there somewhere on the board that has the negative lead? Thanks
Put the negative lead on the metal frame of your TV. You could stick your negative lead into a metal screw hole, making sure it makes a good connection.
What if your getting 3V with PS-ON? I do not see 5V stand by but all other volts on PS going to main board check out.
When I use my tester on my supply board to check for power served in chrome, iTouch TV turns on
Hello Jimmy. Great video! I have a lg 55ln510, #310rmhr7b601 that will show picture for 30 sec and then the screen goes black. The standby light is on when tv is plugged in.

Wow. Dat was epic. Da best repair is to replace da faulty part. Almost like replacing a flat tyre. Congrats man.
Yes, except a flat tyre doesn't have a 5v standby (well I don't think it does)
AT 2:30 into the video, you are testing standby voltage. Using the red test probe, Where are you connecting the black probe?
J Schmidt the black lead is grounded somewhere else on the back of the TV. In a metal screw hole works.
I have a TCL 49S403. Do you know which pin is the standby or should I just check each pin?
Where do you put the BLACK multimeter tip ?? (Ground) while you touch the pins with the red one ?
Hello, what type of mutimeter are you using to check the power supply board?
I have an Element ELEFW328 curb orphan I took in. It's Main & PS boards are combined into 1 disappointing failure.I plugged it in standby light came on, hit the pwr button but no picture.

How could I test my power supply board My board is a APS-352 IS THERE ANY specific testing there in your line thanks
Hi Jim love the video troubleshooting ,I have a 40 inch pioneer plasma t.v it'll play for about a week than it goes out for about a week than it'll play again what could be the problem. Thank you

it doesnt blink when i give power on from the remote control
I ordered a replacement power board for a TCL 55s401 (2 years old) because I had no backlights. Flashlight test confirmed there was a display. I installed the new board from ShopJimmy and I get no response at all; not even a standby light as I did with the old board. Thanks for any help.
I see your red + cable going to the pin on the power supply board. Where do i touch my black lead from my meter? Thank You !
Put black lead to the ground anywhere to the tv metal body
I have Sharp 58Q733Ou and have replaced all 5 backlight strips. Using LED tester at wiring harness, will not light LED strips/ showing open circuit. Have replaced wiring harness but still shows open. All 5 strips light when tested individually. Not sure what is causing open circuit. Thanks
hey jimmy I heard if you have a emerson model LF501EM4 A RED BLINKING LIGHT CAN BE AIR SENSOR BOARD
Thank you. I am from Russia. And your English is very easy and I can understand it. It is great
Hi there looking for some advice I have hitach tv that there is standby light but it flickers blue to red etc pressing the button the tv doesn't come on also my board doesn't show what pin is the standby volt. Do you have an email as I have photo of my board to see if you can help me
I have an LG 42LD690 TV. The power light shows in standby and goes to a wavering red light when on button is depressed. I have checked the power rails to the control board and they are ok. What outputs can one expect from the other outputs to the LED's? At the moment there is zilch. I have no picture.What and where do you think the problem area is? Grateful for any advice. The TV is only 5 years old.
I don't get where the ground lead on the multimeter is supposed to touch
There's that screw above that has a metal tab that the screw screws into. Touch that metal plate it's a ground.
Are you putting the negative meter lead to ground?
Im looking for Proscan 117736 (RSAG7.820.1185) Power Supply Unit. I think it may only be a fuse can I get one of those while waiting for the power supply unit to get in stock?

Hey Jimmy
I have a plasma tv to fix. Lg plasma 50pt350ud is the model. The tv comes on and screen lights but no picture. It will not allow channel change or input change those buttons are unresponsive when pushed. It has no picture or sound.
I have a Sanyo model DP42D23 TV. It has a new P.S. board with all voltages good at the cable coming from the Main board. But it still doesn't come on .There is no standby light that is on. I went to the other end of the ribbon cable from the P.S. Board to the other rf/tuner/line out/in board and all the power and gnd's are good to that point. The board number on the board from the P.S. is NO: PCB J 0995 D1 W46/13. Other numbers on the board are Z7L 305A 49. Not sure if that helps. The power on/off button doesn't turn it on either. I do fine voltage across the power button when press. But still nothing happens from that point on.
Do you think it's that board?
Hi. I have a Panasonic viera plasma TH-42PZ80U TV that will not power on. The red light next to the on button blinks ten times. I am guessing based on research googling the 10 lights, it is the power supply board etx2mm702mf-n. Is that right? Will replacing this board do the trick? Can the board be purchased thru you guys?
Thanks, Dick and Norma

I had a problem with no video on a Vizio 50HG5. I did the flashlight test, and I saw images on the screen, so I ordered the "repair kit" that you offered. I replaced the main board, the power supply board, and all the other parts (I figured they would probably go out soon enough). I tried the TV, and now, not only do I not have any video, but I have no audio, and the TV won't come on, or respond with the remote or the buttons. I would like to return your "repair kit". How do I do this?
"Repair Kits" are something that came-about by "an expert" that got lucky and is opinionated, "more people will have this problem".
Basically, a rip-off that I stay away from. The parts usually work out cheaper if you bought individually, anyway (from the same source, of course).
I have never bought any "repair kit".
Hi Recently my LG 42 inch TV had backlight issue where video alone was not viable but that was too viable through flash light test. The service technician changed the back light LED after which the TV went to standby mode.
Initially he replaced the main board still it was in standby. Then he changed the power supply board. Still same issue . He change TCON board even the issue persist.
But finally when I asked him to change back all three to old board and when testing he was able to recieve supply to all boards. Which initially did not happen.
Now with all old boards and backlight alone changed the TV still stays in stand by mode.
I feel the technician is not having a sound knowledge on the issue and just like that he is saying the LED panel has to be changed.
With your experience do you have any idea on this issue.
Any small hint would be great full.
Thank you.
Hello, I have a 12 month old vizio e48-c2 that will not power on (it began after a storm so, lightning is the primary suspect) I've removed the back panel and the components look like none I've seen on line. There is a small board at bottom center roughly 2x6 inches connected by a ribbon to a larger panel at 3 o'clock roughly 8x12 inches.. I can replace the the tv with a new one for $388. Can you tell me what the cost to repair might be? Is it possible that only a fuse is the culprit? Thank you.
Kind regards,
Billy Hardwick
Hello, I have a LG plasma tv model 50pj350 with sound but no image. I checked the power board and it is working, changed damaged mosfets on YSUS, caps read ok, so do resistors and diodes. Though the VY and VSC testing points shoud read -198V and 135V and I have no more than 60 volts on each. Any sugestion? I’ve tried to get the board diagram with no success. Thanks.
I am a repair tech with 25 years experience in the repair field with a big communication company in Jamaica.The problem I have is with a Samsung tv model number UN32F43AFXZP the fault is it will not power up when the power button is pressed. The power light come on then flash 5 times the off. I have taken out the power board inspected it the caps seem good then I checked all of them they are all good. I power up the board by it self all all voltages are present. Can you enlighten me as to what might be the fault and if it is the main board or power board where can I source these boards appreciated in advance
Follow up - I left it unplugged over night, and it is now working. Yeah! Any thoughts on why it would have done that? Is a major failure imminent? Thanks.
Hey there so a quick question I have a vizio m43-c1 so I have 5v on two of the pins as they should and 19v on all other pins that say +12v while the main board is connected however when I unplug the mainboard I lose the 5v on both pins on the power board is this normal? Thank you
yes
Hi, I recently bought the AS19 T-Con Board Component Repair Kit off your site to fix my 46" samsung tv, model # LN46A550P3F and I am wondering if you have a video on how to use this repair kit?

hi jimmy. i have a sony aps-319 . what happen is when turn it on, it just shows sony on the screen and dark back without any image' what do you think that might be the problem?
I have a problem where my old board gives me power to light up led on front but he board I bought from shop jimmy doesn’t. Any thoughts? Am I missing something? Could I have gotten a bad board from you guys?
Where are you putting the neg probe?
Hello Jimmy, How to look for correct Voltage on Sony G1D board (XBR-65X900C). How voltage should I expect ?
Would have been nice to see where you had the black lead of the multimeter
Any metel part of the board as obviously thats ground.
I have a rca mod #led42c45rqd ser # 2505-ld42c45d100735. The picture would shut off but the sound still worked shut it down and restart and it would work again. Now it starts flashes on for a couple of seconds and turns off. I looked at all the capaciitors and did not see any that looked bad. I only see two boards power supply and main boards. Where would the T-con board be located?
new power board. the tv won't turn on (nothing) I have power at the input on the board after that nothing!
Mate, you're a legend. Such a lovely voice!
Sounds like guy with glasses from Harold Ramis from original Ghostbusters
Is the power board LF501EM4F (A3AUGUH) interchangeable with the power board LF501EM4F (A3AU0MPW)? Thanks!
My VIZIO XVT553SV tv has standby power but does not turn on. It does have 5V standby so I replaced the main board per your instruction. This did not fix the problem. I then replaced the power board per your instructions and the tv still has standby power but does not turn on. What is left for me to check?
same with me
I am looking for a circuit board for a 42 inches flat screen TV model Rc42D1_A
ty is on the picture comes on and off on and off just had the power supply replaced 3 days ago for same problem
If I bought a control board just recently to find out that it is not my Version after replacing the power board I still cannot get the TV to power on mine is a Samsung UN50KU6300FXZA DA01 version and I believe the board I installed was a DF08, is there a difference on versions for the control board that you cannot see that would make the tv still not power on, the circuitry looks identical? Any help would be great could it be the P jog switch? or do I just need to order the proper control board DA01 version
Thanks for the great effort... I have a problem with the Samsung lcd-la32e420, and the problem is the following:
When the power cable is connected to the power, the screen flashes and turns off immediately.. for the knowledge that the voltage measurements from the power board come out intact, especially 5 V.. Can you help me to solve this problem
Hey jimmy, my main board is not given me any power, I suspect my capacitor is bad because went out in storm day
I have a Vizio XVT553SV. The orange standby light comes on when plugged in but the TV will not turn on and the Vizio logo never turns white. I'm wondering if I have a power supply problem or something on the main board? I haven't taken off the back to see if there are any bad capacitors or anything burned or obvious but that will be my next step. Make sense?
+Ron Kirsch After taking off the back, everything appears normal on the power supply and the main board. No bulged capacitors or burned connections. Should I replace the main board?
Hi, tv has standby light but goes off as soon as picture tube wanna turn on, what can I check for?
Hi could be only fuse if not won't power on or no light on power
I have a VIZIO L37HDTV10A. The power light is yellow on the front when it is off and turns on to green when I hit the power button but the screen does not light up. The problem started a week ago when it took longer for the screen to appear and now it will not appear at all. Haven't done anything yet to the set but will take the back off soon. any hints. The video I watched here advised to check the pins for power if it is labeled. Any further help?
what are you connecting the black lead to ?? I didn't see where
Hi Marcel. You can use any cold ground pin on the power supply. You can even just touch the black to lead to the chassis in this case.
Thanks for watching!
So to summarise - If you have 5 volts replace one board, if you don't have 5v replace the other. Not really 'troubleshooting' is it? I could have save y'all time on this video by just saying - "Replace both boards". This isn't really a 'troubleshooting" video. I was hoping for more in-depth analysis of the components on the board to track failure.
Hey bud. I have a vizio, the power does not want to come on sometimes, but when I unplug it and plug it back in it turns on, the other day I had to replace the fuse in the psb. I am wondering what is causing the fuse to blow and what is causing the the power cycle issue
That's pretty good. However, I thought it was going to go into checking components and repairing the board instead of replacing it.
What if I have no red standby light but have 5 volts on one of the terminals out to the main board? Bad main board or could the power switch section fail; the area where the red light is and the remote sensor.
where do I get main power board for 42 inch lg flat screen
If you can get the power supply identification number then you should be able to Google for it and purchase it. I had purchased a power supply board for my LG 60" Plasma television on eBay.
Hi Jimmy. I have a Panasonic TC-19LX50. The stand by light turns in green then makes seven red blinking then seven red blinking over and over and never turns on the screen. Pls advise.
I have a Dynex TV Model Number DX-40L261A12. The TV will power on after unplugging then plugging back in. It takes multiple times to do this. I do have the red indicator light that stays lit. Once the TV is on the picture is still excellent and everything works. I did try another power chord and that is not the issue. What do you think it could be?
I also would like to know where to put the black lead when testing the power supply. The video only shows the red.
me too. I'm assuming it goes to one of the ground pins
Use any screw that holds the board down. Those screw to the frame which is the main ground.
do you need to ground your self before starting this process? If yes then how do you do that ? That might be helpful for your viewers. Thanks
Hi, I couldn’t get any reading on the voltage on the power supply but when I disconnected the cable going to the main board the backlight turned on, so does that mean my power supply board needs replacement or the main board?
Then did you test for 5 volts standby
Jimmy I have a Polaroid
TLAC-02255 and I conect the power cable and the standby light torn on red , When I turn on the tv the red light changes to blue and tries to start the screen apears the logo polaroid after a few seconds turn of and change again to red. I check the power supply and have 2.9 volts when turn on changes to 5volts and after few seconds changes again to 2.9volts
Hello,
I like your service and commitment to help / guide the community to repair the TV.
I have a Sony TV - model KDL52XBR9. It has a blank screen - no video or audio or backlight. When I turn ON with Remote or Power button on the TV, just the Green Standby light comes on.
If I disconnect and connect the wall plug, I hear some rely clicking and the backlight comes on for about 45 sec and backlight turns off by it self. Green standby light remains ON till I power OFF.
Can you please help diagnose the issue?
Thanks, Mohan
My 3yr old Vizio 50in went out so I bought a new board from you. Put it in and it fired right up, worked for a day, turned it off and couldn't get it to come back on. You were supposed to replace this board when one came in. I was told you get a lot of them and would notify me when one came in. No one ever notified me!! I'm still waiting.
Hi Jimmy,
I have LG 70inch full HD Led tv, unfortunately it does not power on, I showed it to a tv mechanic and He said that display panel is not faulty. Replacing a display panel is too expensive, is there any other way or any alternate method.
I have a MITSUBISHI MODEL "WD-60638". When I turn the TV on nothing happens nor does the indication light come on. I tested the 5V test area on the power board and got a varying 1-2V reading. What would you suggest i look at next. Thank you for your time.
where did you put your gnd?
On "ground".
Pins 3-5 as shown 2:08
i have an emerson lf391em4-ds1 led tv and when i check the voltage on pins 20 to 23 of the power supply (on the schema it supose to be at 21volts) it read 11.5volts. what it could mean? thanks

What is the fix for this
@@thaxterpittman2964 throw it out
I have a lg plasma 60pm6700-ub. I believe it was stuck by lighting as the surge protector shows it is no longer protecting. Standby light will blink, when I try to turn on screen shows a faint gray color but never shows picture or sound and then appears to turn off. 5v standby pin (what I believe is the pin) one shows around 4 volts(first time using meter). Any help appreciated

Hi SJ as I was watching your video I ran a few test on my Hisense 50H7GB TV. I notice that when I press and hold down the power on the side of the TV the Hisense logo comes on and the TV picture comes on. The TV well stay on for about 2 minutes then it turns off. I have not opened it yet. Could this be a symptom of the power board?
What u put meter on
I have a Samsung 55" LED Smart TV that during a recent storm made a loud crack sound and shut down. I have verified that all items in the surge protector still work, but the stand by light and power to the tv does not. If I follow your videos, what kind of price might I be looking at if one of my boards needs to be replaced? Before I invest all the time and money I would like an idea if I should simply buy a new tv and if so, what brand would you recommend?
Hi Shop Jimmy, Nice video, I have a LG, LED 55LW5700 tv, I checked all voltages all are goo except the "power on" voltage. It should be 24V and it is only 3.5V, All other voltages are good, does this mean my main board is bad?
I have a SamSung 59" D6900 Series 6 3D Full HD Plasma TV that was manufactured in 2011 that will turn itself on and off every few seconds and is stuck on PC input this first happened over a year ago when I was switching the input source from one source to another too quickly and I was reluctant to dispose of it because when it is on the picture is near perfect ! Very annoying problem if you have any suggestions what part I might need to replace (if I can find one for such an old TV) that would be very helpful thank you.
Immensely helpful!
I replaced both my power supply and main board due to a lightning strike and still no power? I ordered my parts from you. i got them today. I decided just to replace both since i did not see any damage to my boards. I do not have a tester with me right now to test the volts. what could be the problem
Must buy a tester.
OK I replaced the power supply and the main board and still will not power on???? I have 3.3 standby volts on the ps. Philips 47pfl5704D/F7 any suggestions now?? Please and Thank you
no, just gave up i know it sounds bad but i learned what i wanted to know
I have a 60in Sony mod# KDL60EX500 with a black screen. Took the back cover off and no back lights. Used the flashlight test and nothing. I'm sure the sound was down when it went ko as I was using a sound bar. The only way to get power is to plug and unplug from the wall outlet. When plugged in; the green light is on but nothing works. There is no red light ever. When plugged in; sometimes the little square black unit just below the coaxial connection at the main board glows red. Sorry for my rambling. What do you think is wrong and what can I buy to fix? Thanks
