My lg 55eg9100 wont turn on it clicks one time then the light flashes red 3 times and turns off. I have tried the turn off wait and turn on and hold the power button method i read about but nothing changed. Plugged into different outlets too, nothing. Please help Update (01/28/2022)
would you suggest replacing the resistor that goes to the 12v on? Because the only board i found that was reasonably priced sub $200usd was ver 1.4 and mine is a 1.1 there were some differences between the two.
@slyver11 sounds like a board issues. the very first thing you want to do is to follow the flowchart for the “No Power” situation. Measure the voltages as shown. Let us know what you find.
