Green power light stuck on, no picture or sound on TV.

I have a 3 year old LG TV model 65LB5200 LED TV. For the last 3 months it has been slow to turn on. Green power light comes on, yet it was taking longer and longer to come on. Last week, turned TV on-Green power light came on, but no picture or sound ever came on.

sucks.

I replaced the entire power board with a new board thinking it was a bad capacitor. Nope. Still doing it.

Green light is steady, no picture no sound. The Tv will not turn off to a red light either. always a green light no matter how many times i unplug or replug it.

no way to reset it?

Main board?

T-con?

a cable?

Hi Tim, I was wondering if you found a solution to this problem, my television is doing the exact same thing

I did. I'll update you with the part number in the morning. It was a simple replacement. Under 50.00. (Replaced a board - Super simple to do) Will update the actual part number in the morning - stand by.

Hi Jesse Westlund, I am having the same problem with my TV. Green light stays on but nothing else. What do I need to do to fix it?

butterflykisses7846 if you read through the comments and answers to this questions, you will see that it was the main board that has failed. All this will be specific to whatever make and model your TV is as well as what the errors are.

@timmy42483 since you've already replaced the power board, the next check would be the Main board. You do want to check for obvious damaged components as well as the voltages that go from your PSU to the main board.

I replaced the Main Board (both boards) and Bingo....Like a new TV. Just wish I would have started with the main's first before buying the power board.

Do you have the part number(s)? Is it something fairly easy to do myself? I’m fairly handy at DIY things.
