Sony TV Mainboard Mod And Repair From XBR-75X940D to XBR-65X930D 

Thanks to your videos I fixed my Sony KD-65XE8505. The motherboard failed and I replaced it with a motherboard from the model KD-55XE8577. I had to repeat the software update a few times, but it worked and the TV is working. The only option I'm not sure works is the voice command. But thanks 1 more subscriber. Keep up the good work 🙂

Good day. I have a sony kd 65xe8505 tv. I bought a board from a TV kd 65xe8596 after the replacement, the opening music seems to play, the backlight is on, but I have no picture. 12v is on the tcon board. Don't you know what could be wrong? I don't like flex cables, especially the side that goes to the mainboard

Hi Nick. great videos. It looks like there are at least two of us with the problem of Bluetooth not working after a motherboard replacement. What I discovered (in settings/system info) is that the electronic serial number and the bluetooth ID are missing (blank). I believe that this is the reason that Bluetooth does not work. Bluetooth is required for voice commands to work on the remote. Thanks.

I imagine all the equipment cost a bit. If only there was a TV shop like yours around here, I work for free to learn. One thing is for sure, I can get as many TVs as I need to practice on.

Thanks for sharing the information. Can you please advice on replacement of main board ,, can I replace 65 inch sony (8500f) main board with 55 inch sony 8500g main board

Hi Nick, can you help me? I have a kd65x9005b with a faulty main board and I want to exchange it for a kd55x9005b main board but I haven't been able to pair it yet, it keeps alternating between green and orange. Doing the sequence (info5vol+power) I can enter the service menu. Thank you in advance for any tip as it does not accept the update of the file taken from the sony website. thanks

@Nick's TV Repair I have a Sony KDL-65X85J...I recently acquired it as is, when I turn it on, it does with very white faint picture background then quickly change to brownish white Then the tv promptly changes or progress to the standby mode where you hear button interaction sounds with backlight on & sound but noo picture... I believe attempts were made to replace the T-con board but when I try the replacement myself with spare T-con board, the tv power led light would blink x5 times then shut down. When reinstall the original T-con board I would get the first & original issue I highlighted. I checked the output voltages from the power supply board using a odometer & they seem to be in check & balances.... 3.3v, 12v... Besides the lack of picture images or signal, upon closer inspection at the back, far LEFT bottom of the disassembled KDL-65X85J tv, on the buffer board area, 1 of the COF LCD ribbon is removed, unattached. Not rip or torn..is this a major concern??...I will seek to get it rebounded. but how is this ?. Sincerely....🇯🇲

Hey nick can u help me please ? Im from germany and i have the same problem with the hdmi on my sony bravia kd-55X8505C. Then i did a reset and my tv don't starts anymore always in bootloop. I then ordered a new mainboard and installed it, but my tv still doesn't start and I have no picture at all. The indicator flashes green and yellow then it goes off and it flashes again but nothing happens. Does the new mainboard have to be taught in? thank you and greetings from Germany baho

I am the unofficial official TV recycle center in my little town, a computer shop in town gets calls for repairs and he does not repair them so he is sending them my way, most will likely be cracked but I will save the boards.

Can these 2 Sony TV boards be switched oppositely? So put the 65x930D board into the 75x940D TV?

Hola Nick Me gusta tus videos Necesito ayuda con una Tv sony bravia xbr 55x805e software no me da pantalla solo sonido de fondo Ya intente 6 veces y nada ya que la tarjeta Main ya se la cambie pero sigue lo mismo Alguna solución

Hi. I have a 2019 Sony OLED TV 65”. We had lightening strike in our backyard and the screen is dead. Total black. Cable box is ok. Can this be repaired or should I buy another TV ($3,000). Thanks, Paul

Hi again Nick. I contacted the sellers from A*iexpress for Sony KD 55XF9005. Since it is longer than 60 cm (only the led bar is 108 cm, excluding the package), they said that A*liexpress cargo will not be accepted, they can only send via Fedex or UPS. However, in this way, there may be a lot of expenses other than shipping. If I tell them to split the led bars in half, can I re-solder them together? What do you recommend. Thank you very much for the answer.

I have a sony x850d with a completely dead mainboard, no lights flashing on tv, dead set. I didnt seem to find any shorts and all power supplies and boards are good. Do you think this would this likely be the emmc?

Saludos Nick , cambie la eMMc en un XBR-75X857E que no encendia y funciono pero NETFlIX no funciona

What do you clean the flux with? IPA?

How did you learn to do electronic repair, did you teach yourself or you went to school? If you went to school what was it called. I want to do this in my life

Does Netflix still work ?

Hi Nick. I like your videos. I have Sony KD 55XF9005 230 Volt europe model. I have 4 red blinks problem. I saw your videos" ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Y00I6rx70j0.html" and i check the power supply is ok. I have not TCON_12 volt too. In this case, the only possible outcome is that the motherboard is faulty? Could it be the LEDs? My TV was giving an error after working for a few hours at first, I noticed that two of the rear leds were blinking. When this happened it was giving an error right after. When I unplugged it, waited for a long time and turned it on again, it was still working for a few hours. However, this time gradually decreased and was reduced to a few seconds. Where can we buy the jeeps like this one you changed? Thank you very much.
