Hi there,
Hopefully someone has some experience with this TV - yes, it's a mammoth 80" in decent shape other than the plastic falling apart where the screws attach the back cover to TV.
So, when I got it, the TV simply clicks almost every few seconds, small click then another (relay actuating and disarming)
I disconnected LEDs to power supply, and the same clicking. Clicking goes away when i disconnect the mainboard (as nothing is turning the TV on)
I started disconnecting the IR, Wifi,.. to the Main board, and voila.. the TV starts up, I can see beautiful screen with menu and backlight, then it dies (clicks) again, and the cycle continues. I can connect all cable to main board again and it does the same cycle. Seems like it just needed a little push to get in the starting up mode.
I'm guessing there is a deterioration to the power supply board, causing it thermal / over-current shut down. All rails seem to come on on the power supply with the "On" click happens for few seconds. PNL12 V is running at 11.74 V. UR13.2 is running at 13.03 V. 5 is running at 4.92 V.
Thoughts?
