Was watching LG 55LS4500 tv then poof! no sound no picture but the red light on the front is on like it still has power. Took the back off and the capacitors don’t look bulged like they’re bad. Ideas on what to check?
@viperjill post some images of the back of your TV with all the boards and then the individual boards. Use this guide for that. It will allow us to see what you see. Start by checking the power up sequence according to the LG manual
