I have an LG 55LE5400 television and all of a sudden the screen split. The left side has a normal picture and the right side is blurry. Any suggestions?

a heat sensitive component
the only way to find it is with freeze spray and a lot of patience

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.

Does that set have whats called a color wheel, if so that maybe you problem, and replacement is how you fix it.

CALL LG SERVICE CENTRE AND ASK FOR HELP

Our 42" LG picture is also split down the middle. It doesn't matter if it is cable or a DVD. I would love to know if anyone has found out the solution to this prob. The TV is only 3 years old...
