LG TV - powers on, but black screen after LG logo, backlight is on
A few days ago my TV screen suddenly went black and I don't quite know what to do.
Basically, if I turn it on the LG logo will appear for about a second or so and then the screen goes black. although backlight stays on. The only button on the remote that does anything is the on/off one.
Called up 2 tv repair shops and both told me almost straight away that it sounds like the panel is dead and I need to basically replace the whole screen (a $3,000 repair), which I don't quite believe.
When I took the TV off the wall and tried turning it on again a few days later - it worked fine for maybe 10 seconds and then the screen went black again.
Maybe there is a loose connection somewhere or something.
Any ideas? I hope there's something I could try before I throw it away.
The model is LG 70" UH635T, I could find it in the list so had to choose a random LG model when posting this question
