No attempts
If you have to ask this, I assume you don't have the kills to repair a plasma TV. Then please don't start this. Opening it can be very dangerous, and without the technical skills, you even don't know where to look for. Most to the time I advice to visit ifixit, but this time they don't have the manual or video for LG. Perhaps they can show you some openings. But they never show you how to rebuild.
They can help with spare parts. So if you really want to do this yourself. On your own risk:

I work for a auth LG service center and each time I have had this symptom we had to either change what called the T_CON control board or the Plasma display panel itself. You need to cocntact LG @ 800-253-0000 report your problem and they will find a service center in your area you should have 1 year warranty parts and labor.

It is going to be one of two basic issues:
1. There is a poor connection somewhere in the set--either with a plug or cable or on one of the boards.
2. There is a board that is beginning to fail causing this.
Either would require a shop and may or may not be worth the cause.
Having seen hundreds of these sets all are more prone to flaky problems than the older sets and average life span is 3-5 years.
Shop I work for 80% of them are 2 years old or less.
If problem began shortly after set was moved or relocated I would lean towards a bad connection somewhere.
