this is either a circuit board problem or the panel could have a bad tab

Hi,

This kind of symptoms indicated of fault in the Y-sustain board inside the unit. This is responsible for the horizontal scanning. Hybrid module gone to excessive heat due to overload that trigger the symptoms after a period of time of operation. The problem is, this module is repairable only at the service center because this parts and other parts are surface mounted, even we, technician, has a hard time replacing this part.
Check if your unit is still under warranty/extended warranty, avail it because the manufacturer will fix it for free. This board is expensive, range from $200-$300. Don't attempt to open the back cover because it will void the warranty.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Sounds like something you will need to have the professionals diagnose, because that seems like a very uncommon error with that line of TV's. Sometimes TV's just go bad, and need maintenance, especially newer TVs.

this is a upper buffer board problem, the board is not to expensive but the if you are not a repairman, I would not attempt it
