Re: Panasonic RQ2102 mono cassette player
Trev,
There is no easy or magic answer to this.
First start with the basics (which you may well have done already).
1. Ensure the cassette (s) you are trying, do actually have music on, prove on another machine.
2. Ensure (may be difficult to see without dismantling the unit) that the tape is making good contact with the combined Play/Record head, also ensure head is really clean.
3. Try low impedance headphones in the J1 Monitor socket to see if any sound.
4. Try spray of switch cleaner to the Playback/Record switch, I do not know its physical location, but it will be the only electrical switch that is actuated by the Play & Record buttons.
All the active electronics are contained in one IC, so there is not a lot to go wrong, other than a bunch of passive components. If you can see the IC then ensure that the battery volts or the DC supply derived from the mains (around 6 volts) is being switched through OK by the motor switch to pin 14 of the IC, pin 11 is the 0V/battery -ve.
