First you should check the fuse and the wiring in your tv by removing the back cover. Make sure no wires are bare or touching. If there are any, wrap them with electrical tape.
If you cannot see anything wrong by looking, then it is probably the set has a bad transformer (high voltage)

I'm not really sure what causes this but I might be able to help.
I have an LG 42 plasma which had the same problem. In my case I removed the video and the tuner board (they both were mounted on the same frame which was screwed on the tv chassis) and installed them in a "wooden box" so that there would be no electrical contact with the rest of the chassis except from the cables connected to them. It now works fine.

The most commom causes are One. There ia a stuck button on the tv itself. The Menu button. The membrane switch or the TACT switch is bad and needs to be replaced. The Main bd can also be bad.
