Default Pioneer CT-540 tape deck - no playback on right channel

put finger to keyboard and
composed:

I have already fixed the mechanical problem with this deck (idler tyre)
now it plays, fast forwards and rewinds ok but there is no audio output
on the right channel. Also nothing registers on the right channel
bargraph display.

I have followed the general troubleshooting for tape decks in the FAQ;
when I touch the terminal (white wire) from the left head output I hear
a buzz but when I do the same with the corresponding terminal for the
right channel I hear nothing. This leads me to believe that the problem
is in the electronics rather than a defective tape head. Does anyone
have any suggestions for common failures on this deck or perhaps a
schematic diagram?


You can eliminate the head as the source of your problem by
interchanging the L & R wires in the connector. If the problem
migrates to the other channel, then the head or cable is the culprit,
otherwise there is a problem on the board.
