All these sets use two boards (most) inside----one drives the picture left side and the other right side----sounds like your problem.

Contact LG (you listed it here as the brand) to see if this is a known issue with your model and if even if out of warranty do something.

It does not hurt to ask.

You need to replaced your Inverter Board, If you can do the job, get the Board Part number and order it from Westinghouse. If not call a Professional TV Technician. At least you have an idea what's the trouble with your set. Hope this Tip will help you.Thanks

Do an internet search on the make & model TV for a manual.

Hello, it sounds like you need to replace the inverter board on this unit. I would recommend opening the unit from the back cover, get the part # for the inverter board (long green board normally running accross the edge of the TV) and go to www.shopjimmy.com, they should have it in stock and if not you can try www.invertercentral.com, they should also have it.
