Phillips 60" magnavox chassis # PTV843
Hello lagqboy,
It looks like you are having a high voltage problem where one or more of the HV components are failing. The picture starting off small and the growing as the TV heats up is a sign of this (high voltage) problem. The problem experienced when a bright scene occurs is due to poor high voltage regulation. I would suggest that you take this set to a qualified TV repair shop due to the fact that the section I am talking about deals with voltages that can be fatal.
I hope this helps,
Thank you,
Shuttle83
