I have a Samsung Multisystem VCR that is out of warranty.
When playing any VCR tape I get major dropout. i.e. loads of white dots flashing across the screen.
If I bang the machine they will go away. Sometimes they stay away, but sometimes they come back during the course of playing. To take this machine in for service for the problem would not be worth the expense. Would anyone with any hardware knowledge know what the problem is?

Thanks
