Thank you for your question, my name is ***** ***** I look forward to assisting you.

Please note, a rating is only needed when we are finished.

Can you please remove the power to the TV (so unplug it from the power socket).

Then on the actual TV, hold the power button for 60 seconds then release.

Then wait 10 minutes, connect the power again to the TV, turn it on and tell me please if it is now operating correctly.

Let me know the results please

Still the same. Screen stays good for a couple minutes, off on, then screen goes dark. Can still see a dark picture.
TV Technician: Richard, Technician replied 6 months ago

When it goes off, is the standby light still showing?

Responds to on/off from Remote Control. Still a very dark image still showing on screen. Some component maybe going bad when it reaches operating temperature?
TV Technician: Richard, Technician replied 6 months ago

yes, it is pointing to faulting capacitors on the Tcon board, but to be sure, if you press the menu button on the TV remote, how does the menu look?

TV Technician: Richard, Technician replied 6 months ago

Of course and I wish you and your Wife the best

Replaced TCON board with one advertised as NEW. Same problem.
Customer reply replied 5 months ago
Menu goes dark with dark picture behind it. Standby light goes off when initial picture comes on and stays off until I turn TV off with remote and then comes back on in standby mode.
