Hello
From what you described either the screen driver has failed or the backlight has.
If you get a bright torch and shine it close to screen, you may be able to see a very dark picture.
If you can its the screen backlight that has failed.
Either way you will have to take it be be repaired but you may find the cost rather high and will have to decide if it is worth it or to get a new TV.

Picture freezes then shuts off and restarts.


First of all, shame on LG for not providing support on their product. It sounds like this TV isn't that old. I was just bragging on them to several people this week. Your symptoms sounds like a main board issue. But in order to be sure, proper troubleshooting will need to be done to pinpoint the problem. You will have to pay a diagnosis fee, usually $75 range, but for a 55" late model set, I would say it is worth the money. So sorry to hear this, I'm hearing so many of these late model LED TV's failing left and right.

I hook up my pc to lg lcd it always says invalid format any solution


What cable connection are you using? What resolution was the computer sending to the video graphics adapter before you connected the two?

The TV can only support
VGA Resolution: 720x400, 1360x768, 640x350, 640x480, 800x600, 1024x768, 1280x768, 1360x768 or 1366x768
HDMI to DVI: 640x350, 640x480, 800x600, 1024x768, 1280x768, 1360x768 or 1366x768

For best results you should use 1360x768.

Try resetting this when the Input is set to that for the computer. Press Menu and select Picture. Press Enter and select Screen (RGB-PC) (use the Up/Down arrows). Press Enter and select Resolution. Then press Enter and select the desired resolution. Then press Enter again.

If you like there is a Auot-config option in the Screen menu, that may set the TV properly.

If the above doesn't help, use another monitor and check the output resolution and then reconnect to the TV.

I hope this helps.

Plasma Picture going in and out


It sounds like you have a bad solder connection on the video board. Most likely, you will have to take the set into a shop and have it fixed unless you are familiar with electronics.
