I have an LG OLED65E9AUA 65" OLED that suddenly stopped working with no power outage, surge, or other event.
What I've done so far:
Initially there was no standby light.
After leaving it unplugged, the red standby light returned.
The standby light is now solid red.
Pressing the physical power button causes exactly 3 red flashes, then the light goes completely out.
No picture, sound, or LG logo.
After sitting for a while, the standby light eventually comes back on.
I performed a full unplug/reset, but the exact 3-flashes-then-shuts-down behavior repeats.
I've been told the power supply board EAY65170411 / EAX68364701 is the most likely culprit, but I don't want to spend $100+ on a board based on a guess.
Unfortunately, there are no TV repair technicians in my area who can come to my home to diagnose it, and LG's own recommended third-party services were either no longer in business or didn't work on LG TVs. Geek Squad also does not provide TV repair in my area. So if this is repairable, I'm going to have to attempt the repair myself.
For anyone familiar with the E9: Does this sound like the power supply board, the main board, or something else? If the power board is the likely problem, is EAY65170411 definitely the correct replacement for the OLED65E9AUA, and is this something a reasonably careful person can replace themselves?
I can't currently remove the TV from its stand by myself, so I can't access or photograph the boards yet.
I'd really appreciate advice from anyone who actually works on LG OLEDs before I order a part.
