hi,if this tv employs a keyboard unplug it and run the set for a check.

Thanks for your reply,had already done self check and everything checked ok, the fault only seems to occur when the set has been on for about 5 or 6 hours

Hi Techno,

Faulty keyboards are unheard of in Panasonics. All your dysfunctions are associated with the DG Board, not generally a repair item. Exiting the self-check mode will activate a factory reset automatically. Could try running a small fan directed at the DG Board and see if the TV runs for a longer period, to try and narrow it down.
