It's common on all tape decks for the wires from the heads, to break,

I checked for continuity on the leads from the head to the board and they
were all ok.

The other very common thing for no playback on one channel,
is the record / playback switch going bad, particularly if you don't
record often. As a first move, locate the switch, and give it a vigourous
scrub back and forth. If that produces a fix, squirt a little switch
cleaner / lubricant in there, and repeat the scrubbing.


I could not locate such a switch on this deck. For reference, it is logic
controlled. The only internal switches on the transport are the one that
stops the tape if the eject button is pressed and the one that detects if
the 'record-protect' tab has been removed.

OK on that Tim. The record / playback switch is not usually located on the
deck itself. It is normally a slide-type multipole switch, actuated by a rod
or lever or stiff wire, from the deck.
Whether or not the deck is directly controlled or servo controlled by logic,
is not normally an issue, with regard to this mechanical scheme.

Some cassette machines, however, do employ full electronic switching, which
is sometimes part of the record / playback subsystem IC. If this is the case
with your machine, then you will probably not get much further without a set
of schematics, and a 'scope. Have you tried to see if it records
successfully on both channels ? If it does, that at least for the most part,
proves out the heads and their wiring. It's pretty unlikely, but I'm
assuming that you have not got a very badly clogged head ? Normally, you can
still hear something on the affected channel, when playing back a previously
known good tape, but just occasionally, you can get a case that's so bad,
that you get nothing at all.
