shuts down with 4 blinking red lights

My XBR 65x950g started failing a few months ago. It would play for a while and turn off. Finally, and this is where it is now, the TV will start and the boot up process starts. Then the back light starts up and a second later it shuts down with 4 blinking red lights. I tried the BL_ERR pin ground trick but no luck. Same thing happens. Tried a new power board. Same thing. So is it my T-Con board? I have noticed in the start up sequence that a green light come on the middle board, then a small red light comes on and it shuts down with the 4 blinking red lights. I have a video of this sequence but not sure if I can insert it here.

Thanks,

Before I had this same problem, I purchased an electronic repair to my monthly electric bill, I going to put in a claim and let a TV shop do the repairs, I paid a lot of money for that 950G model.

Hi @andreas29338

If you also have a Sony XBR 65X950G TV then according to the service manual, a 4 blink error code could be either a problem with the LD board, the screen or maybe the tcon board.

Same issue. Ordered a kit and replaced all the boards with no change in the action. I also attempted a firmware update after the new install but not sure I downloaded it correctly. Fortunately, I can disassemble and return the parts.

I guess I will buy a lesser brand TV for less than a quarter of the original price of this 6 year old one and consider them disposable, what a shame!
