Hi,
I send in my DSP board from DK in september. Nick's kept me updated in the process. I had it send to family in US. Visited them in late October. Put back the DSP board yesterday night. The TV just turned back on like it had never been DEAD.
THANK YOU Nick's for an outstanding service!!!!
Best regards Johnni
Thanks for sharing!
nicks tv repair fixed one of my tvs many years ago and it still works to this day
Thanks for the feedback!
Sent my board to Nicks for the same repair you might have watched. They did an awesome job!! Sent the board for repair on Friday, and had it back and installed the following Friday!!! They sent me email on the progress. Don't waste time looking for a repair shop or throw your tv away!!! I would recommend Nicks for all your TV repairs!!!!
Hey great to hear you had a postive experience with our circuit board mail in repair service.
Thank you for the feedback as well!
My Sony tv acted excately the same. Then opened it up and checked 12.67v on 3 wires going out from power board, then saw red light on optic plug and tried to switch tv on. And tv turned on! How lucky is that! I did nothing and i got it working again.
Thank you for the video. It encouraged me to try to check it out myself before taking it to repairshop.
Nice!
Just stumbled upon your channel, I’m impressed. Well done!
Hey, thanks!
I believe I have the same issue. Great video production. Enjoyed watching you do this repair
Thanks 👍
Great video showing how to find & repair circuitry fault causing Sony tv black screen & fix to a working screen. Thanks mate 👍
Glad you enjoyed it!
Niiice!🤑 I had one of those about a year ago, and when I tried to take the chip off with Hot Air, I blew off 2 smd components around the Chip and had to get a new DPS Board. lol. I had my air up too high.
Oh no!
Yeah it's got some really small caps and resistors in that area. Definitely have to be careful with this one.
This was awesome video I was able to fix my TV. which I thought It woould never get fixedd. THank you very much
Glad it helped
Mi televisor igual tiene la misma falla donde puedo conseguir ese chips aquí en México
Hy, thank you for the video! You saved my tv. 😊
Glad I could help
Thank you for sharing.
My pleasure!
Hi Nick... I appreciate the content! I'm just starting out with TV repair and love your videos. I had a question about this one in particular. My DPS board is testing good on the fuse, but continuity is beeping on all the capacitors, which indicates a short. However... this is the part that gets me... I am getting 24v to my mainboard still, but have no standby 3.5v. Is it safe to say the chip can be bad, but still deliver 24v to the mainboard? I have watched your mainboard video as well, and everything is testing good on that, with the exceptions of the 3.5v standby power. Thanks in advance!
If those caps are shorted then the IC is shorted and needs to be replaced.
Hi, Thanks for sharing all your wisdom. I have been checking the voltage on DPS Board and even the main board seems to get 24 volt input but I am not sure what you mentioned at 7:02 to 7:06 ( you said and also 3.4v). I don't seem to find any of the wires showing 3.4v. Can you shed some light on what that 3.4v for and also, any other way I can check whether that was the cause for the NO Power for the TV - XBR-55X930D). Thanks.
Sorry for very late reply.
The 3.4 volts would be found on the right side of the 3 caps I believe. The caps we use to check for shorts.
I believe left side is ground and right side is 3.4 volts.
Hello! Thank you for the informational videos. My sons room has a xbr-43x800d…all of a sudden no power. I checked and appropriate voltages getting to main board. So I ordered a new main board. It arrived and I installed it. Now I have power but nothing else…ie, plug in and nothing comes on screen but green light blinks 14 times and then stops for a few seconds and then starts again (green light alternates with white light that typically comes on when tv is on). Any thoughts?
Yeah check out this video linked below, should resolve your issue. th-cam.com/video/gBd2g7kRsEM/w-d-xo.html
Hi like your videos, your channel is very informative.
I have the Sony 65X930D.
The screen turn on black and white and the tv has to be reboot several times for the tv to work.
I had this tv for over 5yrs now, I can buy a new tv but I like to solve problems like that.
What’s your recommendation?
That is a strange symptom that I have not seen or heard of before and I don't know what could be causing that. I would highly recommend doing a factory reset as well as a sotware update first. If that does not resolve the issue, I would then tend to suspect either the T-con or the screen itself could be at fault there but that is just a guess.
Love these videos! I’ve been trying to learn electronics repair for a bit and got my hands on a Sony xbr-55x850d with no power(due to a power surge). The external power supply was toast so I replaced that, but there are other issues. When unplugging the main board from the power board, the backlight comes on. Just took the board out and trying to figure out what’s next. Do you guys have experience with these boards, and if so, do you plan on releasing any videos on it? Thanks!
Hello Taylor,
We do commonly service those as well. We don't have any videos on that specific model right now, but we are planning on doing a video on it in the future. But it won't be right away. I already have a few other models we are working on first, but maybe in a month or so we may have a video for the 850D boards.
Thanks for the video! Can you please tell me what the part number is for the IC? I found TPS54334DDAR elsewhere but that chip appears out of stock for the next year or so. How would I find an alternate chip for the 65X930D TV? The three capacitors are also shorted on my TV.
The three caps are shorted because they are in line with that chip right. So if you remove the chip the short should go away.
Try different suppliers such as digikey, Mouser, Arrow and so on, they should have that IC. If they don't, you can call them and sometimes they can guide you to other replacements that would be compatible.
Hey, I love the video. I definitely dont trust myself with tackling this. I have a 4k Bravia that doesnt power up as well. Did you say that you are willing to do this exact thing for hire? I could use the help with my wifes tv. Please let me know.
Yes, here is the link to the service www.nickstvs.com/store/p2296/A2094368A.html
Hi mate, nice work.
I have a sony TV have same circuits boards as the TV you worked on. My tv not working and has red light blinking 4 times.
If you can tell me which circuit I check and replace it, i did some research most of the articles says the problem could be from power board or backlight board??
Thank you Nick,
4 blinks is typically the backlight or the LED driver board. I would recommend replacing the driver board first since it's way easier to do that than the LEDs.
I looked at another video of your's and you mentioned the white wire 3.4v is for standby power. Thanks. I looked at the main board fix by following your video ( Dead Sony TV No Power Sony XBR-55X930D XBR-65X930D Mainboard ) and the resistance test passed and capacitors looks good based on the test. I felt stuck at this point on how to proceed further. As you have mentioned EMMC chip could probably the issue but I don't have a way to confirm that. Please do share if you have any.
Sorry no way to check the emmc that I am aware without desoldering it and checking it in a programmer.
If you now have power after fixing the DPS board everything should work. If you still don't have full power, it could be that either a cable or ribbon was not properly inserted back in and you may have to reseat all cables, it could be 1 of the pins on the IC chip was not soldered down properly, the IC chip you have is partially defective, which unfortunately can happen, or it is also possible that your mainboard is also defective in addition to your DPS board which is rare but we have seen happen at least a dozen times in the hundreds of these we have had to service.
I would start with double checking your work, double checking all ribbons and cables first and trying to boot up the set again. If still nothing, I would then replace the IC with another in case the first one is defective.
If you still have issues after that, then it could be something to do with the mainboard.
I am sorry but I don't think I can help much more without having the boards in hand.
@@NicksTVRepair Thank you very much.
Nick, what temperature do find works best on most IC removals? I have a new hot air gun for some Ham Radio projects, my Sony XBR65X930C is still working fine..
Modern Ham Radio equipment uses a lot of SMD so getting the temperature in the right ballpark would be important.
Thanks
Robert, San Diego
My advice is don't listen to what I say or anyone else.
Your machine is unique to you and the way you use it. Practice using your machine on dead boards or donor boards, learn how your tools work, try out different nozels, get a feel for what your tools can and can't do. Every circuit board and IC chip is different, there is no universal heat profile that fits all.
The only thing I can tell you is that more heat at a higher volume of air flow for a shorter period of time is better for components and the board than doing less heat at a lower volume of air for a longer period of time. At least that's what I have found in my personal experience using my tools.
Again your tools could be different, so don't listen to what I have to say. Find out for your self by trying out different things.
Also i aid it already but ill say it again always practice on bad donor boards. Everyone has this tendency to practice on the super-expensive boards that aren't replaceable.
@@NicksTVRepair good advice and thanks!!
Hello Nick. On my DPS board I get 24VDC out but do not get the 3.4VDC out. All 3 caps are also shorted. Would you call this a bad DPS board? Particularly that IC you removed in this video?
Yes that is exactly your issue
Hi i saw your vlog.
I have an issue with my OLED TV (XR-77A80CJ). I change the main board, power supply board T-Con but still it will not turn on. What would be the issue then? Hope you can give me some of your ways and methods to fix the problem. Much appreciated. Thank you
Hello,
Well, you replaced everything in the TV so if the TV won't turn on after replacing all the boards either there is a piece of information that is missing here, or you replaced your defective board with another defective board.
When you say it won't turn on, can you be more descriptive? Do you get power? Are you saying the screen won't turn on or the TV won't turn on? The TV can turn on without the screen turning on. The same sentence can mean different things to different people so please provide as much detail as possible so that I understand what you mean when you say it doesn't turn on.
PS 9 times out of 10 the mainboard is the fault.
Eres un capo
Thank you
I replaced the ic bought from your site. It fixed the short. Now when i plugged everything back in I'm getting the 24v on the white wire out of the dps board instead of the standby voltage. And nothing in the center wires where you looked to be testing the V out of the dps to mainbaord. It ended up shorting the ic again. Good thing i bought 2. What could be causing this? I placed the IC exactly as you had shown.
The bottom pad may not have been soldered properly as in improper contact or maybe too much solder and could have been making incidental contact with another pad it shouldn't have.
Without seeing it in person I am only guessing.
Hi @NicksTVRepair Great Video.
I do have 75X940D working fine since last 5 or so years. Suddenly one morning it was not powering up. It's been like that since last two weeks. What would you recommend. Upgrade or Repair?
In my biased opinion I would say repair. That's because this is a very good 4k TV and once you get the mainboard fixed, there aren't any other parts that commonly fail with this set so you wouldn't be at risk of another problem arising anytime soon. Oh also replacing this 4k 75" Is going to be between 5-10 times more expensive depending on the model you go with.
@@NicksTVRepair Thank you for your prompt reply. I am glad with repair option as A90L is almost another $5000 which I was aiming for replacement. I would like to send it for repair. I also have filled out contact us form on your site from my hotmail account. Let's discuss next steps for repair option.
@NickTVRepair I just have placed a repair order. Do I need to buy tools to open the TV Motherboard?
You just need a screwdriver to remove the screws. Be gentle with the LVDS ribbons (the large flat ribbons) they are fragile and can break if you don't disengage the locking mechanisms correctly. We have videos on removing a Sony mainboard if you need.
Hi Nick, I replaced the chip and worked for a few minutes then it stopped. I checked the capacitors and they are short again also the fuse has blown up, what you think is the problem that damages the chip?
Maybe the ground pad didn't solder properly? Are you sure you had a genuine replacement part installed? I just asked my tech that does these repairs, and he told me that he has never had that happen before. Unsure if you have a more severe problem and something else is at play or if the part you used was bad or possibly not sodlered on right.
I identified this IC as the shorted part thanks to your video! Now where do i find this part. I have had 0 luck searching for it using the tv model number or the numbers on the chip itself.
I have a link in the description where you can buy a replacement chip
@@NicksTVRepair I dont even know how I missed that link. I should have checked this comment before ordering the part elsewhere. I was directed over a part that is called "TPS54334 4.2-V to 28-V Input Voltage, 3-A Output Current Synchronous Step-Down Voltage Converter". Did I make a mistake or is this the same part?
Nick, what is the clear flux you use and where do you get it?
KINGBO RMA-218 no clean soldering flux
Hey, Awesome Video!!! The Chip you replaced where did you buy the new chip?? Can’t find it in Birmingham, Al or anywhere close. Thanks!
Check our video description, there is a link to our website, we sell it.
@@NicksTVRepair 4:28
Could you tell me the part number that was repaired on your video? can’t make anything out of all of these pictures
Nick,
I have a Sony XBR-65X930C with out any power. The board is different from the one on this video. You have any video that have similar board from mine to show me how to troubleshoot.
Thanks,
Toan
Hello Toan,
I don't have a video for your exact TV model, but the concept is the same and I can already tell you that your mainboard is the fault, but to confirm you can follow along with this video:
th-cam.com/video/Y00I6rx70j0/w-d-xo.html
We do fix those mainboards if you did want to send them in for repair, just reach out to us via our support email or by filling out the contact form on our online store. All the contact information is in the video description.
So i need to check check the voltages like you did at the 1:55 min mark to know if my 24v stops on the dps board to know to send it in? thanks
The best thing to do is not a voltage check but the resistance check of the 3 caps to the right of the IC we replace. Take the board out of circuit or simply disconnect everything from it to make sure nothing in line affects the reading.
In resistance mode test the resistance. If the 3 caps are shorted then the IC is bad and needs to be replaced and thus confirms the fault is the DPS board.
@@NicksTVRepair do you have a walk through of how to locate and check those three caps? Thanks for reply
Where do we get another IC chip online? Is it the IC408 chip as listed on the board?
eBay would have them. Yes it is the IC408 as listed on the board.
Nick, I have a Sony XR-75X90J that won't turn on (it just shows the Sony logo, then turns off). The LED light flashes red 3 times. The TV started turning off during a rain storm so I suspect power surge. You think I should change the main board or the power board as well?
Manolis,
If your TV is showing the sony logo then it is in fact turning on. Since your TV is turning on, your power supply is most likely not the fault. I do not know what a 3-red blink stands for as it is not available in the service manual I have access to but if a lightning strike occurred then yes 99% of the time a power surge affects televisions not through the power, but through the data cables and internet which all connect via the mainboard. If this were my TV, I would start by replacing the mainboard.
@@NicksTVRepair thanks! I just connected the new main board. No red flashing led. The screen is backlit but nothing else happens. I tried updating the firmware with the USB drive but nothing different is happening. Any ideas?
Hey Nick I have a similar model with an amazing picture and I fear this just happened.. do electronic repair shops fix TV's?
We do, if you want to send me an email with your exact model number of TV and symptoms, we might be able to help you fix it. Our contact information is in the video description as well as a link to our contact us page.
A question as to how you know which IC to buy, or under which reference you got it. In my case i have a problem with a Sony XBR-65X900E Tv with IC401 problems. Can you Help me
I typically work with symptoms first and confirm the fault before jumping to specific IC chips. What symptoms do you have with your TV?
@@NicksTVRepair The TV does not turn on, it is completely off, the standby LED does not turn on either. I followed the measurements with the service manual and in IC401 I have absent voltages, in the manual it tells me to replace IC401, the number on the IC is: P001 PHVG 640Y
Thank you for providing the symptoms. Yeah, I have no idea what IC401 is.
I have never had to replace IC401 in the hundreds of these mainboards that i have fixed. Granted I don't have a 100% success rate but 90% of the time a dead no power issue is due to the eMMC chip. That's the chip that usually needs to be replaced when encountering the dead no-power failure. The only other part that could cause this is a defective processor, but that usually only happens due to a power surge or lightning strike taking it out. It's rare to see it go out and cause a dead no power on its own although it is technically possible.
Hi I replaced same ic on my Tv but it only lasted 8 months before shorting out again. Do you know if Sony made a board revision to this issue? Maybe better off finding the entire board if it’s been redesigned to not short out? Thanks
There could be a few reasons for that. #1 this is a known fault which Sony has provided an extended warranty for. The issue is common but within 8 months is very fast, a little to fast to make sense. #2 the chip you got could have had some defect. #3 the chip was partially damaged during the installation. It is easy to apply to much heat and partially damage the chip as it does need to be installed with hot air.
There is a modification you can do after installing the chip. It involves adding I believe a 72k ohm resistor connecting pins 1 and 8. This should help reduce the power draw I think and thus extend the life of the replacement chip. I don't know the specifics exactly but thats more or less what I understand.
Please look more into it before doing this, I could be wrong with this information.
@@NicksTVRepair Thanks. Do you know if the issue involves heat? Would adding a little heat sink help or something else?
My multimeter on 20v does read a AA battery correctly so i believe its working properly and when i check the power supply at the port as you do at the 1:10 min mark it reads 19v and instantly drops to 13v and drops or starts at 13v and continues to drop, never any where close to 24v and drops eventually to nothing, what does that mean??? Thanks for helpful vid
You may have an issue with your power brick not making proper contact. Is the plug perhaps not providing 24v correctly from the power brick if you play around with the cable? If you put it in a certain position vs another does it more consistently provide voltage?
I only mention this because I have seen this be the fault before.
If you still have issues, I would recommend sending us a message directly or by filling out our contact form.
The contact info is in the video description.
I used the brick and cable from my 900E which is the same type 24v, same results shows 13 volts and drops instantly. Any ideas? @@NicksTVRepair
We have a Sony XBR49X900F just go out the Geek Squad said that the power supply and mother board were out and that he could not fix it so they credited us the full price of 850 USD to buy another TV so we purchased a LG 55B2 OLED.
It bugs me that this TV went out, it was in the bedroom so barely used not like the TV in the living room, no power surge or lighting just went out. Is it repairable and what do you think it will cost to repair, I can put it in the hobby room.
Hello,
I am very sorry to hear the Geek Squad was your only source to service this TV set. Sony TVs are very much worth fixing. Without even seeing your TV I can with 99% certainty guarantee you the power supply is fully functional and the Geek Squad representative did not properly diagnose the device. Not because they are not a good tech but because that is the diagnostic process imposed by best buy. "replace it all just in case"
Your mainboard 99% of the time is the only fault with the set. We are very familiar with fixing these boards and should be able to fix yours without a problem. Our circuit board repairs always come with a 1 Year warranty and are typically performed in 3-5 business days. For more information on the repair service and price, please see our service listing linked below:

@@NicksTVRepair I was wondering why he was using a flashlight to view into the TV, could it be that the power supply is not working as well?
I have your site now so I will be reaching out again.
Hey Nick i have a KD-65XD9305, no power, i checked the steps you showed, and power is getting past the part in the video( the other side of the last cable checked) no sure what else to do now any advice?
If I understand your comment then it seems your DPS board is working and your faulty board is the mainboard. I would recommend replacing it or having it fixed at this point.
@NicksTVRepair understood thank you for the quick reply 👍👍
No problem!
Good luck
the caps on my DPS bpard are shorted but Iam getting 24 volts on the cable from the DPS to the main board
so those that mean I have to replace both DPS and the main board
I don't believe so but I can't tell you for sure. Most of the time only the DPS board needs to be fixed, however on some occasions we do see the mainboard also being affected and needing to be replaced.
I wouldn't be able to confirm this for you without having both boards in front of one of my techs.
If you would like to send in your boards for repair, we do service both, we can fix your DPS board which clearly needs repair, and live test the mainboard for you to ensure it is functional and if not repair it along with the DPS board.
thank you@@NicksTVRepair
hello Nick, do you know which pin is the protection line of a 55XD9305. tv standby flashes red 4 times. this tv has an led driver and a dps board
If you have the XBR-55X930D north american model equivalent, then you can disconnect the thin ribbon on the left side of the DPS board that connects the DPS and LED driver board to one another. Disconnecting it will send an auto on signal to the LEDs. If the LED's turn on, and there is good illumination through out and no fickering of the LEDs then you have confirmed your LEDs are good, your driver is good and the issue is somewhere else.
If you don't have your LED's turn on, then either your LEDs need to be replaced or the LED driver may be defective.
@@NicksTVRepair hi Nick, when I disconnect the ribbon cable. The backlight is on and no shadow at all. Where do you think the problem is 4 x blinking ?
Hi. I have this model tv. There is no power. No tv light at all. No standby or blinking lights either. Tv will not turn on with remote or power button. No optical light either. I did step 1 test measuring power coming from ac adapter at 24 volts. Step 2 I measured led driver board but it sparked. I then measured power coming in at Dps board. It was 24v and power leaving Dps was 24v and power at main board 24v. I did not see any other voltages at Dps or main board.. I followed your other video and removed main board and heat sink. I then tested the resistance in all the capacitors you had mentioned. All the capacitors showed shorts. This makes me think this would be main board? I wonder what would cause main board to go bad while in standby mode overnight? I also tested the Dps board and the fuse was ok but the 3 resistors were shorted.. it would appear I need new/repaired Dps board and main board. One thing that was odd was that I had no voltage on the white wire just 24 volts tested on the Dps and main board. This happened overnight while tv was off and was plugged into surge protector outlet strip. All other devices plugged into surge protector outlet strip were fine. What are your thoughts about what is wrong?
The way this fault occurred and the way you are describing the fault occurring overnight is very common. Based on everything you mentioned especially regarding the slip-up on the voltage check which caused 2 pins to short and spark it may be best to send in both the mainboard and the DPS board for us to check as both are possibly affected at this point.
It is also not unheard of to see both the mainboard and the DPS board fail at the same time although it is a lot less common.
For more information on my services, please see the website listings which are linked in the video description.
If you have any more questions regarding your set or regarding sending in your parts to be tested and diagnosed, please reach out directly via the contact info which is also in the video description.
Hi I replaced the dps and main board and the led driver board. Now I have the red optical light when on standy by. When I power tv with power button or remote I have a solid white light in the bottom middle to show tv is on but the screen is black. no picture. Do you have any ideas on this?
Hey! I checked the wires from the DPS to the main board and one does give 24 V. There is no 3.4 V though. The capacitors next to the chip are shorted and the fuse is shorted (intact). Do you still think it is that chip? Is it worth sending in to you?
Yes!
They don't always fail in the exact same way but if the caps are reading a short in circuit, then that means that IC needs to be replaced and of course we can do that.
Awesome. Do you have a video on how to remove the cables from this board?
@@NicksTVRepair nevermind. Found it!
I have followed your videos for this TV, I was able to troubleshoot a faulty main board and a faulty DPS module. I am still not getting any standby lights or signs of life at all. Where do I go from here?

@NicksTVRepair I just received the main board and DPS board from your repair dept. After install they still seem to not be working.
If I can't run down the problem myself, may I mail you the boards?
Hello,
Yes if you have this TV, it can be tricky to identify the fault. We do on our website have both flat rate services for each individual board, but we also have a testing and diagnostic listing for $20. What I recommend is you send us an email directly, make sure to provide us with both the model number of your TV, as well as very clear and detailed symptoms you are experiencing. From there we will either tell you which board we believe you should be sending in, or if 2 parts can cause the same symptoms then we would recommend you send both in, purchase the diagnostic/testing bench fee of $20 per board, once we receive them we will, of course, test them, and identify the faulty board. The fully functional board will not be refurbished unless specifically requested, and the defective board will have its $20 diagnostics/testing fee credited towards the cost of the repair.
Does that make sense? If not or if you have more questions then I would recommend you reach out to us directly. Our contact information is in the video description.
Thank you
Hi where can these chips be purchased from and do you have a part nos
Sorry for the late reply, we just started offering them for sale
I have posted a link in the description
Im having an issue with an 75x850e no power no noise no screen lights at all stby power is good zero power at the tcpnn pins on the main board.
Then you most likely have an EMMC fault. If you want to send in your mainboard for repair, we can fix that for you.
Simply go to our website which is linked in the video description and type in your full correct TV model in our search bar to find the repair service.
Your full model number is XBR-75X850E
Hi mate I have sony kdl-42w805a I think mainboard is gone no power dead. What chip needs replacing. Thanks
Sorry I am not familiar with that model. The newer TV sets, it is often either a shorted processor or software chip. Those are the 2 common culprits. Yours is an older model, so I am not 100% sure.
Does it make any difference using a TPS54334DDA instead of TPS54334DDAR ? I have a TPS54334DDA and i'm wondering if it's safe to use.
Yes, that I am aware of those are interchangable. You shouldn't have any issues with it provided it was sourced from a reliable seller.
@@NicksTVRepair thanks 🙏
Hi! Just found your channel. Very impressed! I used to make my own sircuit board and built radio remote plains, amps etc......40 years ago. And now i'm stuck with Sony - 75" Class - LED - X900E Series - 2160p - Smart - 4K UHD TV with HDR which i've been having a lot of issues since i've baught it in 2017 paying $5200. And now - no power. Did all the trics with reset (worked before), but now it feels like id doesn't have any juice. The TV just died while I was watching it (without rebooting as it happened before) I don't wanna through it away, but I've seen how you used hot air for soldering. Do I need it? An if I will have the same problem, where can I buy cheap?
If you have an XBR-75X900E and it seems to be dead, you most likely have a bad EMMC that needs to be replaced. I don't think it would be something I would recommend performing on your own.
Here is a video you can watch where we change out the EMMC.
th-cam.com/video/XadBVYLJOVM/w-d-xo.html
It's very involved and unless you have the correct equipment and experience, I don't recommend doing it yourself.
I know I sound biased because we offer a service on it, and that's what I am trying to push, but these are very hard-to-find boards it's not really the type of board you should be experimenting on and seeing if you can fix it. You should practice on a low-cost $15 circuit board first, once you get the hang of it and are able to successfully perform the repair on the cheap low-stakes board, then start working on the hard-to-find and replace boards.
Again I know I sound biased, but if you want to send in the board for repair, here is a listing for it
nickselectronics.com/products/xbr-75x900e
Sending it to us would dramatically increase your chances of repair success.
Good day, sir.
Pls teach how to remove(disconnect) the flat cables between :
1) dps bd and main bd x1
2) dps bd and lcd bd(located downside) x2
These connctor are so hard to disconnect... Not a simple lock style..
If you watch the video until the end, there the next suggested video is exactly that
If anyone has black screen with backlight after the ic change , replace the ic again , a lot of faulty ic-s are out there , i changed the ic , tv turned on with black screen , so i thought it was the t-con board , i said i will replace the ic with another new one , and it worked , screen came up again !
Some chips are sold shorted already. Recheck the board for shorts and make sure the shorts are gone before installing the board back in.
Or you can buy the chips we sell from our website linked in the video description, those are known good, they are a bit more expensive, but they work first try everytime (unless improperly installed)
@@NicksTVRepair Thankyou , the tv is workign after i changed the chip again .
dear nick what is the problem if sony kd-55x7000d tv remote not working and no light at the tv bottom? i have the the remote it is work on same model thank you
Most likely a bad mainboard
@@NicksTVRepair I see Thank you Very Much .You are a very kind Master
Hi,what cause my sony tv if i plugged in it show static white lamp at indicator.already check no power to tcon board.
I am not sure, that is not a common fault. You could have a defective mainboard but for this model it is not common for the mainboard to fail with that symptom. I never see the DPS board fail with that symptom, I also can't imagine the power supply failing otherwise you would have no power. The T-con maybe, but it's very rare for it to go out. You can try replacing it first, but if that doesn't work I would then say to send in your mainboard for us to test in our TV and double check for you.

Hi .. I have an Sony Bravia xbr-65x900e .. when My tv is plugged only Sony log appears on screen but no take actions at All from my remote control or the power button located on side of tv and the led lights at bottom no turn on .. any suggestions that what can be?
Hello Adrian,
Yes that is going to be a mainboard related failure. That is a circuit board and a symptom we have fixed many times in the past. If you want me to fix it for you, I do give a 1 year warranty on the repair. All you need to do is purchase the service linked below and wait for the email instructions

@@NicksTVRepair Hello Nick thank you for your quick response and link sent .. yes I would love if you can help me repairing the mainboard.. I have a question.. would you do the update of software if necessary ? Or should do it my self? Thank you again
XBR-85X850F no power no stand by light..dead .. any recommendations?
For the 850F model I would say that's most likely a mainboard but there is a small chance you could have a power supply fault.
Try this video on the XBR-75X850F I made. I do some checks on the power supply. Your set is the 85" version of my 75 I am working on but it's going to be similar.

Even my TV optical light coming red, what should I do, model SONY KD 55A1 OLED, BLINKING 4 times Red light
4 blinks is going to be a backlight failure. If you have an OLED set, then I don't think you can fix that.
I would highly recommend you go to a local shop to have it double checked however.
Please answer me fast XD
I have 900f and my tv just goes black and is just the picture blacklight is on too but the picture just disappear and it looks painful when it happens it has sound on too
Hello,
I don't know what could cause this specifically without diagnosing the set in person. This is not a common fault for the TV to stop providing picture but still has backlight and audio.
This could be a panel fault, or T-con fault. It is unlikely but there is also a small chance your mainboard could be causing the fault.
If I didn't have a way to diagnose the set further, and I were in your shoes, I would start by replacing the T-con, and then the mainboard since the T-con is cheaper and more readily available. Just make sure to locate modules with return policies in case you have to return the module.
We can live test the mainboard for you if you would like, and may be able to also fix it, if it is indeed defective depending on the exact cause of the fault.
Sorry but unfortunately I can't provide more details without having he TV at the shop.
@@NicksTVRepair hey thanks for it i really appreciate it, if i can i well send it there, i need expert tbh, but thank you for giving at least the possibilitys
What's the cost to repair it...if that's the damage? (Average)
We have a flat-rate repair service which we linked in the description. I want to avoid providing that info and links in the comments as scammers are rampant on TH-cam, and could fake the account and logo. All the information will always be in the video's description with links to our website.
Hello Nick, if i order this ic chip from your website will it work on my model ? kd-55XD9305..
Short answer, yes, I believe your model uses the same chip.
If you click on the link I provide to our website for the sale of the IC, it will have very clear markings on it. It should say 54334. If the IC on your board has the same numbers on it, then yes it will work for you.
And in case you can't check, I believe there is a 99% chance that your set uses the same IC.
My tv after fixing it from the orange and green alternating lights issue, now doesn't turn on a day after.. no power, no standby lights.. how do I fix this please.. Sony Bravia tv 55 inches..
Am in Ghana
Hello,
Knowing what the initial issue was along with what part you replaced to fix the TV would be helpful to know so that I can better understand the history of the set.
But generally speaking amber green = Mainboard needs pairing.
You can check out this video with instructions on how to do it:
th-cam.com/video/gBd2g7kRsEM/w-d-xo.html
If you can't get the mainboard to pair, either your ribbons are damaged, not seated properly, or the mainboard has an issue.
please can you help me with a video on sony andriod with a green screen
Jerry,
what is the model number of your TV and when you say a green screen, do you literraly mean that the entire screen only displays the color green? Does audio still work? Were there any intermittent issues prior or did this all just happen just one day after turning on the TV?
I have never encountered an issue where only the color green, would appear on screen. I assume you either have a mainboard or T-con issue.
Without knowing what TV you have however, it will be difficult to help.
Where to buy this IC, please?
Digikey, Mouser, Arrow are all good options

Hello,
it sounds like you have the cycling on and off issue that is commonly caused by the mainboards. If this were my TV, I would either get a new mainboard, or get my original serviced/fixed.

I have many TV not working
We have lots of videos, hopefully they help you figure out how to fix some of the ones you have.
If not and you have a request for us to cover a specific TV let us know and if we commonly see it in our shop we will do a video on it next.
I spent $200 buying a power board, main board, & T-com board, for a 58" Sharp with picture & only standby power light on. Nothing worked. Can't send the parts back to JimmyTv. Save your money, buy new.
I think you may be misplacing your frustration.
First I am sorry to hear this has happened, I understand how irretating that can be.
I would like to add however that the 58" sharp sets typically have LED strip failures. So indeed the parts you purchased wouldn't have fixed that issue. It is a slightly tougher diagnostic to make and can be easy to miss if you aren't familiar with TV repair.
I think a good diagnostic is very important to avoid purchasing the wrong parts, which is why I create these videos, to give you insight on how to properly diagnose your TV the first time.
@@NicksTVRepair thanks for the reply. I have no tv repair businesses near my location, unfortunately. Lesson learned.

HELP...just found your channel...my Sony XBR 900E has no power/led. I haven't used the TV in a while but I get no light or power. I tried a second AC adaptor and that didn't work. I opened the back and tested where the power plugs in(Small little board) for 19 volts and that seems fine. From there is a middle board, then---->Board with the inputs. No light from optical. Anything else to check?
