I had this same issue a year and a half ago, the tv is only 3 years old. It is a 55 widescreen. When they came out to repair, all they did is reset something and run through a manyal convergence of the entire screen. Any ideas on what might be causing this, and how to reset the set again? I am at a loss here, and at this point am ready to fix and sell the darn thing.
Any assistance would be great, my wife stays at home and babysits kids to having a tv is a necessity.
Thanks again in advance.
