Re: LG 40UB800V-ZA won't power on, no video or audio

I've tested all 3.5v, 12v, 24v and 37.8v points on the PSU board and all seem to be as they should, photo of the boards coming up.

Hi,

I have an issue with a 3 year old LG 40UB800V, it's an LED backlit to.

It started playing up about 2 weeks ago, would take a few minutes to turn on, then gradually over the course of the next week got upto about 10-15 minutes.

Yesterday however it failed to power on at all.

I had hoped that the caps on the PSU board were bad, they all looked good but I changed them all out anyway, still, it wouldn't power up.

I have a stand by light, when I try to power on the tv it flashes a couple of times then goes out, after about...
