The one where you plug into a different plug brought the TV pic back crystal clear immediately! I've been struggling with my TV for three to four weeks and it took longer and longer for the picture to come back..Thank you so much for posting that video !

Unplugging the TV and plugging it back in after 60 seconds did the trick. Thanks. My TV is an LG webOS NANO85UNA.

Number 4: Throw the goddamn TV out the window.

My picture went dark, but sound was still working. I tried hdmi cable first, no effect. I tried unplugging everything next, and this worked great. Thanks!

What is holding the power button on the remote going to do if you just unplugged the tv from the wall. This is stupid!

All three you suggest are to do with power, so how as in your description does the TV turn on???? Its just got no power hence the black screen...

Mines a lg plasma 50ps3000. The top half of the screens gone black, the bottom half's perfect. I've bought a Y sus board fir the tip half, im hoping that solves the problem

LG C9 77… If I am getting power, and it is turning on with out a picture, could it still be the power supply? Have had 2 people look at, one says dead panel, and the other is saying he wants to switch out the power supply with a new one….

Took a few go's reset worked & u know what I did last, I pumped the A/D button back n foward like heaps of times, from analogue to digital, the analogue isn't operational in Australia anymore, any I pumped it real quickly like 20times roughly then boom picture came back on 100% no issues, try soft & hard reset 1st a few times, then if nothing pump A/D Button, good luck lg tv is 20years old to its back 2 perfect with chromcast & firestick etc.goodluck 🖥
