No,body can cofirm u have to troubleshoot change the boards to know the problem.

Are there any blown caps on the PSB-power supply board. Most sets have sammy boards and they used very shotty caps. If there are no visual clues being a poped cap at the top (X) they simply often do vaporize and dry out. The YSUS-Main and the 2 Y buffer boards control the picture OSD-on screen display. Your not getting any of that. So power supply is where you start first. The YBU-upper and the YBL-lower control the upper and lower OSD the Ysus main control both of them. Usually if you have one in the door you have to replace all 3. But not always. If you were to replace any of the boards I would replace the YSUS-Main, or get the board reworked at a pc repair shop that does board level test and repai. Its more cost effective.

sounds like your tv in shut down mode why lamp needs 2 be replaced nominal cost 120 200$

The Ymain Board is out if you have the back of the tv exposed disconnect the ymain board and then plug in the tv set and turn it on. the light should remain green and no longer flash. If this happens the Y main and upper and lower buffer boards should be replaced

here is a link to the manual faq are in there sound like software

I think its something on the picture frame board or on the line output board. I would sway to the line output simply because I think but not sure that error code is linked to the line output stage plus when you unplugged the cable the voltage seems within parameters. Good luck.

Most likely the YSCAN UPPER board and/or YSCAN LOWER Board also gone. Your new YSUS board may damage again if you don't replace the bad YSCAN boards. Try to replace the three boards together and then to verify which boards are bad one by one. Good luck.

After you remove the back cover inspect the power supply board for swollen or bulging capacitors. Pull and check any capacitors that you suspect to be swollen. Next, look for a sticker in the upper right hand side of the TV set. Use the values you find on the sticker to calibrate the voltages on the power supply board.

Mine as well, no good solutions yet...
