Hello!

I have a Panasonic DMR-ES30 DVD-VCR with a problem.
When i play vcr i have a lot of dropouts in the picture.
The brighter the picture the more dropouts.
It looks like "satellitesparks" as you get from a sat-dish witch is
not properly adjusted to the satellite.
If you have a dark picture then the sparks almost dissapear, but you can see
a white line flashing from left to right occasionally.
If i record a video and play it back on another vcr then the picture is perfect.
The audio is ok, no distorsion or flutter.
I have cleaned the videodrum and controlhead but to no improvement.
The groundwire between mechanism and pcb is ok.

Does anyone know what causes this?

Thanks!
