Hi all, My Grans Panasonic video recorder of 4 years young has developed a fault; When playing a tape, the picture is fine for 10 seconds, then a white noise bar appears at the top 1/4 of the screen and stays there. Its not the tracking and the heads have been cleaned. It looks as though the heads don't think they are on the tape properly and are moving to compensate. Anyone have any ideas please? Is it worth repairing given that the new model of the same vid is only £90? Any help would be appreciated. Cheers! Paul.
