Re: XBR-55X850 turns on but no pic no 12v on t-con

Thank you Nick's TVs for your detailed answer. I currently have a friend who does board level repairs looking at the main board to see if he finds any issues. When I get it back I will do the pairing procedure again. I have tried it 5 or 6 times, are you aware of any on screen prompts or is it simply plug the memory stick in and leave it?

Hello,

I have a Toshiba 50L711U18 and the backlight is not turning on. Tried using a flashlight and I CAN see an image. My phone also tries to connect to the chromecast on it as well. These two things are telling me that the T-con board and the main board are most likely working properly. I opened up the front of the display to get at the backlights.

Yeah I would assume the backlight error voltage should be 0V, any idea what could cause the main board to throw that voltage?

Hello, I have a Sony XBR-55X850C and I have no backlight, no display but I do have sound.

When I first turned the tv on it flashed 6 red LEDs. Looked up the code and it said it could be the backlights or the main or power supply board. I opened the tv up and seen that the main board was getting voltage for a few seconds then shutting off. I disconnected the T-Con board, the backlights came on. It was displaying a series of colours. I turned the tv off and plugged the T-Con board back in. When I turned it on the LED...
