Here we have a 32 inch Samsung LCD TV. In this video we are going to discuss some basic troubleshooting methods for a Samsung LCD TV that does not power on and does not have any standby light.
In most Samsung LCD TVs we have four boards. We have the main board, the power supply board, the backlight inverter. The backlight inverter can sometimes be covered by a plastic or metal shield. We also have the t-con board. The t-con board can also sometimes be covered by a shield. Click the link in the video for more information on the basic functions of these boards.
If you cannot power on your TV, the first thing you will want to check, is that you have the TV plugged into an outlet that is working. After making sure that the outlet is working, you will want to check and see that your TV has a standby light. The standby light will be blinking or illuminated on the front of the TV. If you do not see a light in the front, then you do not have standby. If your TV will not power on and you do not have standby, then you most likely have a problem with the power supply board.
Here we have a close up of the power supply. You can look over the board and do a visual inspection looking for any raised or puffy capacitors, or any burnt or damaged components. Here are some examples of what a puffy capacitor or burnt and damaged component will look like.
If you have any damaged components that look this way, you should replace the board. If there is not a replacement board available, you can also try replacing the individual components or purchasing a repair kit.
Removing and installing new components requires the ability to be able to solder.
When looking for damaged components or burn marks, you can also look at the bottom side of the board. You would simply need to disconnect all of the cables and then remove the screws that hold the board to the panel.
Be sure when disconnecting cables and removing screws, that you take a picture of what the board looks like in the original state with all of the cables connected, and then you will have a reference for when you reconnect all of the cables.
If all of the components look good, then you will want to check the fuse on the power supply board to see if it is blown. Here are some images of what a blown fuse can look like. Some TVs have glass fuses and some ceramic fuses. The glass fuses can show visual damage when they are blown. The ceramic fuse does not and would need to be tested with a meter.
If the fuse is blown, replace your fuse and then plug the TV back in. After you plug it back in, if the new fuse blows immediately, then there is a power supply board and it should be replaced. If the fuse does not blow, then you may just had a power surge or another problem that caused the fuse to blow.
If you fuse is good and you do not see any visible damage on the power supply board, the next step is to use a meter and start checking voltages on the power supply board to see where the problem is. This kind of testing requires specific equipment and a specific skill set. Be sure you have the proper equipment and experience when checking voltages.

Video posted 6 yrs ago and still more detailed than anything newer i have been able to find. Thanks for the info!
My TV had no power and no red light. I watched this video, took a gamble that it was my power board was defective as they said in the video. Ordered the part, swapped it in and my TV powered right up. I'm glad it was a $50 fix, instead of a $1,500 new TV. Thanks for the informative video, and the replacement part.
thank you thank you thank you, ordered a new power supply from you and I have my 50" tv working again ! ! !
Found two "puffy" capacitors..spent $3.50 for both.. soldered them in and my 11 year old TV works again. Thank you!
My 32 inch Samsung around same age just a few weeks ago no image on screen no sound , just have red standby light on in right corner , pressing won’t turn on set . This model has no physical power button anywhere . Might open it first time. You convinced me with the price you fixed yours . 🍺
Thank you!!!! Got a replacement power supply from you guys and switched out the part. TV working again! 😁
@1:46 thanks man i found the panoramic capacitor issue in my tv with the help of your video ..

Followed this Video on my Samsung LED TV. Found it was the power board. Ordered from ShopJimmy. Replaced it and $35 dollars later TV is up and running. Never done this before, I’m a healthcare professional not a repair person by any means. Figured ide give it a try, if it didn’t work, not much lost.

Dear Mr Jim my.
Thanks for explaining tv repairing videos.
I am facing one problem, one Sony Bravia LCD TV.Panel is out of order(Power supply board and main board is OK. )my quistion is with out replacing the panel there is any solution for repair this. I am waiting for your valuable reply.
Thanks and regards.
Th
Thanks so much you save me lot of time
Video helped me figure out what the most probable fault is and how to fix it. I decided to purchase the full repair kit and I will replace the power supply board first and go from there. If the $80 I spent on the kit gets me a few more years of outdoor use on my Samsung TV, I will be a happy guy. I will update this post when the kit comes in and I install the parts.
Parts came in just as expected, very easy to install with just a screwdriver. TV works great again and I am holding onto the other parts from the kit just in case.
Thanks for making this so easy.
The alternative considered was to buy another TV. $80 well spent.
Keep up the good work.
Which repair kit?
What do I do if the problem is not the power board?
Very nice simple explanation. subbed
have fluke will check
Thanks for this great video... I have a Samsung LN32C350D1D 32 “ tv..... It started switching randomly between inputs, then turning itself off and on. A few weeks later it just stopped turning on completely. I have a red light showing it has power, but when I hold down the power button there is no blinking or change of the continuous red light. I took apart the back of tv to visually check things out. I took pictures and since I am new to this, I thought I would ask you what you suggest. The tv is very sentimental to me as my father bought it for me and was very pleased and proud to give it to me. He recently died and I want to keep my tv as long as I can...it is sentimental for me.... according to your tips, I am leaning toward capacitors. I would very much appreciate your advice...thank you. ..
Thank you I learned something new
@shopjimmy.com is it possible that the main board is bad if I have no image no sound and no standby light? Checking the power board with a multimeter I have the standby voltage and the capacitor, fuses and diodes are good on the power board.
Thanks mate...I have no idea from electronics,but I had a Samsung TV (le32r32b) with opening problem.I follow the steps and I found a problematic capacitor,I change it (it cost me just 1 Euro) and BOOM!!!!!!!hehehehe now my TV is playing just fine,thanks.
Undid screws cant get bad off samsung tv
nice video--thanks
The best video ever posted on repairs. Thank you. I have not removed the cover to test it but the liught will not turn on and no light. I tried disconnecting power and then reconnecting to now avail. I will probably end uop needing a new board a UN65NU6950P.
Hi,
i have a Samsung UN55B7000WF that's has had the flashing red light followed by some clicking then the same process over again no picture. I check the PowerBoard and see no visibly damage on the caps so next i would have to check the stand by voltage on the PB my question is can you let me know if my Jensen JTM-95 is OK to do it with? and if you can let me know if i can replace the red and black leads i have with a pair that has smaller tips to check the voltage when the connector is connected?
Thank you for the video. I have a 32" Samsung flat screen and don't see a fuse but u do think there are some components that look puffy as described. The blue ones on mine look just like the ones in the video. I only paid like 150 for the TV. Would it be worth it to get it repaired or should I just get a new TV?
Ur a legend man
Also there is a polyester capacitor near power IC 56nF/630v that looses its capacitance.
Hi, Thanks for your videos. I have a question on my samsung TV repair.
Model Number: Samsung TV LN40A550P3F
About a month ago while I was watching TV the picture suddenly went off with with distorted vertical lines and buzzing sound noise. I pulled the plug to turn it off.
The next day it started normally and was working fine until this week. The same problem happened again but it never came back on this time. I followed your videos to trouble shoot.
1. Standby light is blinking but the TV does not power on.
2. The 2 fuses on the power supply board are good
3. I don't see any visual damage of the capacitors on power supply board or main board. main board gets power from power supply board. I checked voltages with multi meter.
4. I don't see back light on or picture when tested with flash light.
Any ideas where to go from here? Anything else to identify the problem?
Thanks!
Thank you for posting your troubleshooting videos. I have a UN48JU640D Samsung that is a year and half old. The Standby light initially comes on but when turning on the TV it doesn't turn on and the Standby light flashes (1 long and 5 shorts flashes) . Do you know what that error code is indicating. Thanks
damaged ic on the main board ,replace the damaged parts or the main board
Thank you for your reply. Do you know if the flash sequence is a failure code and if so where can I find a list of the failure codes.
It was a chance of replacing a board, but I had replaced the main board and it works.
My Samsung smart tv turned off while I was watching it and never turned back on. It was only a couple of months old. What can I do to fix it?
Bro how many voltage going power suply to main bord plz tell me

Thank you
Samsung plasma model pn60f5300afxza version us01 won't turn on no standby light, swap power supply board with a known good one still doesn't turn on? Could it be the main board? Suggestions please?
Would Lowes carry fuses or Home Depot’s?
Big thanks Jimmy just an internal fuse out, wrapped abit of tin foil around that baby to bypass it now all is good until my fuses arrive.

I've a sony SR29M69K tv. I've not used it for about 3 years. Now, when I switched on the tv I could see a light along the edges of the tv for a few seconds and it went off. I've checked the fuse. It is ok. Where the fault could be?
I had a blown fuse on the power board it's a T3.15ah250vp ceramic. I purchased a 325A250v ceramic put it in and it sparked bad!! Is it the wrong fuse and I killed the TV for sure?!?! Had trouble finding the exact fuse with all those numbers and letters
Hi, my lg tv 32lf5610 seems to turn on with a dark screen but the optical audio input has its red light on, ive measured all voltages and only 1 from the power board list is 0 volts but also there is no power going to the leds is it the power board?
Hi, you mention to check the fuse on PSB, for the glass fuse that can be visual inspect to see if there is a burned out thru the glass, but how do we inspect the ceramic fuse to see if it's burned out or good? Thanks.
Okay I have a Vizio TV that won't power on. I replaced the power supply board and it still isn't powering on. What do I do? Do replace the other board? Model # e470vl
I have a Samsung LT27A550LR/ZM, it tries to turn on, but after few seconds, he just don´t. I read few forums that says its a common issue of the power supply. could be this or the main board?. I cant find the part number of the power supply and I rather not open the TV (but if there is no other way, I' ll do it). thanks
Yeah I figured it was something like that so I went ahead replace that bank of caps that were all swelled up, there was also burnt diode that was right next to them but I had to replace.
I do appreciate the video though thank you.

Hello boy, I have a problem with my Samsung TB model UN46D5500RGXZD. Can you help me? The problem is turning on is 3 to 5 seconds on and then off.
Would that be the same for led tv that will not turn on no standby light or power! I have another tv with broken screen! Easier to swapped the screen to bad or swapped the power supply from damage screen !
How do I test the ceramic fuse?
i have a philips tv model # 46pfl3908/f8 - it will not turn on. not stanby light but when plugged in I can hear a low squeak/ chirp
Hi, Hope you can give some direction. I have a 55" Samsung LCD
TV Model # UN55B8000XF. What happens is the TV will click when it is
plugged in. No power on. When I disconnected the logic board, the
clicking stops (saw in a video). Background...this was a friends TV.
He told me that three of the HDMI connections failed after a near
lightening strike and they had to move the input to the last one. That
was a year or so ago. Two weeks ago, the TV suddenly shut down while
they were watching it. The only thing it does is click about every six
seconds..... any thoughts would be helpful. Thanks Rick
2023 this vid still informative. Even for a dead qled tv with no standby light and won't power on.. power board it is 👍🏾
I have a 2015 Samsung J5190 series that doesnt power on and no stand by light. I looked at the power board and everything looks ok. It's got a ceramic fuse, do you have to know how to sauter to replace the fuse? I'm going to also buy a new cord. It doesnt have any visible damage but I dont know what else to do. Need some help here
TV Samsung UA40J500AK how can you help the fuse on the power supply keep on browing up whenever I replace with the new one
I changed my power supply board and it worked for about a month. Now it stopped working. I already spent $86 on a power supply board, could it possibly be the main board?
sadly power supply section was not case of no standby light / dead tv in my case. I had to buy new motherboard for 20$ and everything worked. Probably it got somehow high voltage from antenna cable or other device via hdmi and it got damaged. Remember standby light is going directly from motherboard, not power supply board so no standby light mostly means damage of one of these boards. It does not point if TV has power, it points if motherboard is working correctly.
What's is the amps for the 40 inch smart Samsung tv,fuse.thanks
what will happen if my tv says to add t3.16(slow fuse) but i added a f3.16(fast fuse)?
I just replaced the power supply board on my Samsung 55 in tv. The powersupply board shorted out, and I purchased a new power supply board, as well as the other boards, and associated cables. I still have no sound or picture. The stand by light does come on, but it did after the powersupply board shorted out.
Great video do you all have the power board for Samsung the board number is L55S6R MHS BN44 00807F
Good day.I have a Samsung S51AX-YB02 . I get no power and When I opened it I see a green blinking light 2 second intervals and then it stops. I can't get it started no power or clicking sound either. I checked the fuse and it's good. Any suggestions. Thanks for your help.
Hi when capacitor or resistor or other components burnt / damaged the components how to find the value of a compound with the value 1 components erase the value of damaged components help me
Gd pm, my samsung la32c450e1 no power, no indicator light, b4 I will replace my power board can you give possible voltage check present in good and bad powerboard? Thank you for for the help
i have Samsung Led model UA24ES5400 won't turn on and can't see fuse anywhere on power supply board. Help pls!
On my Samsung tv the fuse has a green stripe on it. Does that mean the fuse is still good? Thank you. Great video btw.
i have samsung LCD 46'' there are pictures test signal white line.how can i remove that test line?
my Samsung plasma tv pn42a450p1dxza has no power going to it at all what could wrong with it.
Where do I go to get replacement boards?
I have a Sumsung 20 inch tv. It will not power on. But I can't find a fuse on the board. Can fuses look different than the ones you have shown? The tv is only about a year old. This problem started when I turned off a circuit breaker and then turned it back on.
Mine ended up being the fuse soldered on the board. We heard a tink and nothing screen and all power dead. Have had no problems before this and T.V. is about three going on four years old. The whole power board is $24 online and the fuses are cheap but soldered on the board. It was just under $20 with shipping for the fuse kit so I went with the power board. Now I have extra parts if the capacitors blow
I have a Samsung UE46D6507VKXXE tv that stopped having white light when power cable connected. The standby light keep blinking and I can hear a clicking sound. Since the standby light blinking and is on but no light/background light and signal from TV, does this mean it's the T-CON board that need to be replaced? I have tried to replace the power supply but still the same problem. Thanks!
i recently replaced my power board and the tv goes on fine but when i press the input button it shuts off. thoughts?
matthew viera make sure you have all bolts on the power board on I was missing a couple bolts when I put mine in after I put the missing bolts in worked fine Hope this helps good luck
my 50mp4700 lg wont turn on i check everything but i dont see damage the power supply is sold out everywhere
Do you have tcon ic for devant 55 the number is HX8894C-B1H-E1
Need help undoing couple of connectors on the power supply board of my tv - it seems impossible to remove
Hello,
I have a SAMSUNG PN60F5300BFXZA and after a lightning storm have no standby light. I have replaced the power board, but still no light. Do you think replacing the main board is the remaining issue? Thank you so much!
Did you fix it?...the same thing happened last weekend!
What would be the issue if the screen keeps going out? But there is power coming through. It happened when plugging in my iphone to one of the USB ports?
I've never had a problem with my Magnavox 50 inch tv. Yesterday I picked up the remote to turn it on as usual. No power, no lights, no nothing. I reseated the plug. no luck. I did a 10 second power button test. no luck. I plugged the power cord into another flat screen it came on immediately.. So I'm assuming now that tv's just go out at anytime with no warning at all. I'm pretty depressed about the tv not turning on. I'm assuming its the power supply. I've replaced computer power supplies but the tv power supplies look a bit different. I'm thinking of doing a DIY. I am a computer tech. I have repaired thousands upon thousands of computers and laptops. Yet never repaired a tv. Do you think I can repair the tv? Any quick pointers. Is it easy to take off the back panel. Should I be very careful about certain things? my tv is a Magnavox 50 inch flat screen model number 50mf412b/f7 has no power? Thank you.
Hi I have a samsung PS-50C96hdx Plasma TV. It was working fine then switched it self off. When it has power connected the blue light comes on and is solid. (I believe this to be standby mode) when I turn the TV on whether with the remote or with the centre button I hear the power on sound/chime then the blue light goes off and nothing. I have had the back off to check the capacitors and there is no visible signs of any component damage. I am going to take the fuses into work tomorrow to test.

Similar to Tevarius, I have a 2014 Samsung UN40H5201AFXZA that also doesn't power on and no stand-by light. The only thing that happens is when I plug in the power cord, the stand-by light flashes 6 times. I tried the power board, the main board and the T-Con board, still no power up. I even disconnected all connections from the power board and the main board trying to isolate the problem and the stand-by light still flashes 6 times. I'm suspecting the P-Jog button because it's the only thing that I didn't unplug. What do you think?? Any help you can offer is much appreciated. Thank You!!

I have a Samsung 46 inch flatscreen, and the model number is LN46d503f6fxza and I went to your page and typed the number in and it showed up that you have a power board in stock, is that the right one for my tv? it's 54.43?I turned my tv off one night and it never came back on, we had a bad storm about two weeks before and my house was hit but the tv kept playing fine until last night, the red light won't come on or the tv won't come on, do you believe the power board is the problem?
sgf129 I've got the same TV with the same issue.
I have a Samsung TV when I turn on it takes several times to find picture it clicks on an off before it comes on what can I do?????
Would a bad power IR button cause the TV to not turn on? I have no puffy capacitors or blown fuses and when I start unplugging power board the TV back light comes on.
I have a Samsung le26d450 TV. Takes about 10 minutes to come on from standby. Pulling out the mains lead temporary fixes problem, comes on then goes off for few seconds then comes back then it works fine. All the caps on power supply board look fine. Any ideas.?
Forgot to mention I'm in the UK.
I replaced power supply board but still no standby light, what’s my next step
I have the same problem, my tv is UE40MU6402U. The repair guy told me that power supply board is to expensive to change, so I've ordered it from your site, I've replaced power supply board and still no power on tv. Any sugestions?
The device has malfunctioned due to power loss during the upgrade tv samsung smart UE46ES6905U
show me how to check voltages with a voltmeter...does not need special equipment to check voltages
what voltage of zener diode should i use for lg lcd power supply
58V
UE40C5100QW is not working, no power on, just blinking red point
what i have to check ?
I have a Samsung LN-S4051DX that won't power on. It just clicks and has no standby light. I've tested all caps and they are good. And when I test the power board, I am getting overvoltage. Where the 13v pin is, I get 18v until it clicks, then it goes down and comes back up to 18, then repeats over and over. The three 6.4v pins are at correct voltage until the click, then they go down and come back up. And last, the 12v pins all have 26v, then drop down and back up. Board looks good. No burnt spots or cold joints. Sounds like a humming noise coming from transistor the whole time it's plugged in and clicking as well. Any ideas?
Quick question (anyone well-versed can answer),
My tv (samsung model LN55C630K1F) quickly turns on and off with no standby light. I’ve summed up the problem to be the main board but that’s where i’m stuck... Replacing the main board (BN94-02701E) seems impossible (can’t find it anywhere) nor can i find any of the suitable substitutes listed by shopjimmy.
Soo here’s the question, my assumption is that the mainboard is going into self protect mode due to drawing too much power. And I don’t know how to fix that. Can someone explain that or option 2, can i replace the mainboard with any other mainboard that fits?
