Aiwa HV-MX1 FF/REW problem

    After 8 trouble free years my Aiwa HV-MX1 VCR has started having
    intermittent problems with FF and REW. Sometimes it works fine other
    times it will not FF or REW.

    When it fails the take up spool (terminology?) will spin slower than
    normal and the free running spool (terminology?) will have the brake
    applied. The brake is stronger that the take up so the tape does not
    move at all. The mechanism, however, continues to try and drive it
    until you intervene. Simply press STOP and it may work properly on the
    next try.

    Anyone got any ideas what may be causing this behaviour. Is it likely
    a logic issue i.e. the processor or a feedback problem i.e. mode
    switch or something else altogether?

    All other functions appear to work correctly.

    TIA,
    Dave

    Maybe the mode switch needs cleaning?

    A+s+i+m+o+v

    .... If all else fails, hurl it across the room a few times!

    Thanks for the pointer Asimov. Cleaned it up and now it works
    perfectly. I didn't even consider that the switch would be so easy to
    disassemble for cleaning. Now getting to it, that was another matter!
