Orion TV/VCR TVCR1921A Won't Accept Tape

    Hi,

    I have an Orion TV/VCR combo model TVCR1921A (mfg 9/97) in my
    shop. It won't accept a tape. I replaced the belt (loader) which was
    slipping, but the problem remains. The loading motor will rotate in one
    direction (loading direction) briefly, then reverse. If the TU end sensor or
    IR beam source was the problem, the loading motor would not rotate at
    all since pushing in a cassette "breaks" the beam.

    Thanks in advance, Brad

    Mechanical alignment, broken teeth on one or more than one of the plastic
    gears, defective mode switch, defect in mechanical load mechanism that draws
    tape around drum, Etc.

    Oxidized mode switch is a common problem. If the cpu doesn't see a
    state change quick enough, it times-out and backs up to unload mode.
    I have good luck cleaning with methanol and a fiberglass brush, then
    lubricating with a light film of antioxidant oil like de-ox-it.

    There's also a power supply problem that can cause this. If too
    much sag or ripple happens when the loading motor runs, the CPU gets
    confused. And there's a 6 Volt regulator IC that goes bad in some
    models...

    Brad:
    As the other two replies have mentioned, I would bet a dime to a
    doughnut that the problem is a dirty mode switch.... and/or slipping,
    stretched and worn loading belts.
