I have the Panasonic tx-58ax802b which has presented a problem. The tv could turn on sometimes and display picture fine but most of the time it would turn on and after a few seconds it would flicker between picture on then off. Usually a hard reset would help but it would still eventually lead to to the same problem. I have taken the panel off and without being an expert, it looks like their are signs of damage. Is this an easy fix ( replacing components) or will the board need replacing do you think? Any thoughts or help would be much appreciated.
