OK, it seems few capacitors on power supply board are failing and causing less/ insufficient volt supply which would be affecting picture quality, please keep using TV to see if problem get worse then swap power supply board in TV as first thing to resolve the issue, please click following board supplier link to get replacement power board as different version of power board utilized in this model so make sure you're getting identical one if want to replace it by yourself in TV..
