my TR- 355 has stripped gears on the REC deck take up clutch. Can't
find a service manual or part number, so even if I knew where to get
them, I wouldn't know what to order :-(
might be worth checking these parts on yours -if the mech senses no
take up, it will shut off. But do check the cass-in leaf switches as
Arfa says, I have see this problem numerous times, most recently on
Sony and Panasonic decks.

Hi!

If it's not engaging in the recording mode, have you checked to be
sure the record prevention safety switch is doing its job?

There should be a small arm that senses whether or not the erase-
protection tabs have been removed from the cassette. If the switch or
optical sensor attached to this arm aren't working, the deck will
refuse to record on a tape.

If it's a switch, you could try shorting across it temporarily and
attempting to engage the recording mode. For a full logic deck like
the one you have, you will need to have a tape in place for it to work
properly--otherwise the tape spill sensor may well shut it down if it
starts in the first place. (Most won't operate without a tape in
place.)

I don't think that is it: the record-enable switch will (generally, on
every cassette deck I've seen) make it impossible to even engage the
deck in record mode at all. The OP's description seemed to indicate that
the deck would engage when play+record were pressed, but would then
immediately shut off as if at end-of-tape, suggesting some other problem.

I just re-tested. Makes no difference whether record is enabled. It
does 2 fast clicks and stops, forward or backward. The 2 clicks
occur slightly faster for backward.

There are a series of contacts just above the cassette. I cleaned
them as best I could with alcohol and Q-tip: made no difference.

Thanks,

I don't think those are contacts; those sound like the springs to hold
the cassette in.
