How to Fix SONY Android TV Not Turning On! (Main Board Swap!)
Рет қаралды 56,596
Күн бұрынI picked up a Sony Bravia XBR55X810C for FREE that stopped working and challenged myself to see if I can get it working. Symptoms include no power on plugging into the wall and testing turning it on. Power board in standby showed voltages just fine. After swapping power board, TV stayed off. After swapping MAIN board, TV is alive again!
How to fix:
1. Remove back cover
2. Test voltage of power board with cord plugged into wall
3. Order appropriate board
A. No voltage on power board? Replace that
B. Yes voltage on power board? Probably main board issue
4. Swap the board
5. Put it back together
6. Should turn on. Good luck!
I hope this helps someone out there! This process should work for these TVs as well: XBR55X810C, XBR65X900E, XBR55X800E, XBR55X900C, KDL75W850C, XBR65X850C, XBR55X850D, XBR75X940D, XBR65X810C, XBR65X930C

Hi Edward, my model is XBR55X810C, dead LED light (everything appears dead). How can I first eliminate the Power supply? I’m reading 3V only on the 3rd and 4th pins on the button row of the main 14x2 pin connector # CN6401.

Hi Edward. Great video! A question: Did you need to update the firmware on the replacement board or was this a plug-and-play situation where the new board worked immediately without needing to download an update from Sony and the TV was immediately operational after the replacement? Thanks for your guidance!

👆🏻 exact same question I had! Thanks for asking. Just went back to a TV repair shop and rescued my TV. They wanted $400 to replace the motherboard. When I told them I found the part online for $89 and I would just assume do it myself, they tried to scare me with updating firmware and downloading who knows what. 🙄 I’m taking my chances and buying a used part on eBay. :)

Didn't have to update the firmware. Check the other boards for swelled capacitors or potential burns. If inclined, there are pins you can test voltage.

HI thanks for the great info . We have a Sony XBR 85X 850D which was working fine in the morning but when we came back from work was dead and no power or light will come on . We were able to take off the back cover . Noticed there are 4 boards in the back . Tested the 1st board using the multi meter and verified the 110 AC coming in and out . But the 2nd board which we think is the 2ndry power board had 110 Volt coming in but we couldnt verify voltage going out . Now we couldnt test the 3rd( some kind of green tuner board) and 4th board (main board ) . We are in the process of ordering the 2nd power supply board but would like to know how to test the 3rd and 4th board . Any insight in this will be helpful . Donot wanna junk the TV as its just 4 years old and was working fine before went to mars

I have a Sony Bravia XBR-65X850C. I just put a new main board in it yesterday and it fixed the issue. Tv came on. All worked good. I then powered off. Unplugged, setup on stand went to turn on. White light illuminates but no backlight or screen comes on now. I then did the software update using usb and after the white light finishes its flashing process at the bottom it then stays solid but still no screen illuminating. I do hear sound if i hit the source button on TV ill get a chime that comes from the speakers. What did i do wrong ugh

Questsion! I think my xbr75x900f needs a new power supply board (blinks red 3x and turns off on its own) I can get a board for 75$ but the shop said even tho it’s plug and play… Sony parts require programming… you don’t do programming in your video… so are they lying? Should I just order one and try?
