But now here's the kicker. I've had the issue for 4 days straight, then this morning before I headed to work, I turned on the TV just to see if the error was still there and it was gone. The TV has worked all night without issue so now what? I am fortunate this happened when my extended warranty was due to expire in six days! Now that a technician will be coming out, the problem has gone away. Is it possible for the power supply or main board to go in and out of functionality like this? I'm afraid the tech will report that no problem exists and therfore it doesn't need repair. Then the day after my warranty is up, the problem will reappear. Will the tech be able to isolate the fault based only on my description of the symtoms? Any ideas?
Well, tough call on this one... Has there been any brown outs or electrical storms the day or night before the issue started??
If so, unplugging the TV for a hour will kinda reset a hardware glitch. These TVs have power on all the time, there has to be some power to the main board to allow remote to power on.
If the issue does not pop up before the tech shows up... you can explain as best you can what has happened since your call. Ask him if he can remove the power supply and mother board.
Once both are removed, have him look at the bottom side where the circuit traces are.
If any of the traces are discolored in a local area, brown /reddish so to speak. It would be easier for him to call it defective. One or both may have some circuit damage.
I had my main board damaged from the power supply and both showed the discolored traces from heat stress of failing parts.
I too had issues that would randomly pop up after the TV warmed up, but did not realize it till much later, as we only turn the TV on once during the night and never use the controls since Directv and our A/V receiver do all the functions.
I was able to fix my main board as it was easy to diagnose the fail parts.
So in a nut shell, none of the boards should have discolored heat stressed traces.
