Question about Televison & Video
The first thing that should be done is to replace the convergence ICs (STK392-110). Then you need to check all resistors if they are fine , also check for any cold solder joints. Please contact Panasonic for the part nos as it is always recommended to use original parts.
Please do accept the solution and revert for further assistance.

The problem with no picture, but working sound, this is a loss of the high voltage system. This is almost always failure of the high voltage auto transformer called the flyback and/or the HOT (horizontal output transistor) - which work together in producing the horizontal scan of the raster system and the high voltage to produce the raster upon which the video picture is modulated.
The failure could very well be from HIGH temperature involved with the storage of the tv set.
Let me know for any clarifications.
