STRANGE VIDEO DRUM MOTOR PROBLEM

I have a late 1980s low end vcr (Sanwa - also badged Lögik, Orion,
possibly Saisho etc) with an unusual problem. It came to me 'dead' -
with the 1.25A fuse in the power supply open (not black).
I replaced it and the thing seemed to work but soon I noticed that
when you stop the tape, the thing unlaces as usual, but the drum motor
does not switch off - it spins very fast, sounding like it's
'hunting'. The power/stby switch does not react either. If you put it
into play when this hunting whine is going on, you get a distorted pic
which clearly shows the drum's going too fast. So far i've yanked the
plug to avoid further damage. Obviously this i pretty worthless, I'm
just curious to see if anyone else recalls this problem and what
causes it.

last night I had another look at this. I cleaned the mode switch and
no joy. it worked a short while, then once again again after pressing
stop, the drum kept spinning wildly and couldn't be stopped. Strange
thing was you could put it in and out of play (with a tearing fast
pic)..After about a minute the drum stopped - and since then ain't
come on again....looks like another for the scrapheap...
