Check:
- Wires unsoldered from head.
- Dirty rec-pb slide switch.
- Dirty function selector switch.
- Missing voltage to preamp circuit, cracked solder, wire off, etc.

Expanding on what Ben said, select tape mode, put a blank / unimportant recordable cassette tape in, hold down the STOP button and, while holding that down, repeatedly press and release the RECORD button a good few dozen times. If it makes some horrible noises initially while you are doing that, that's a sure sign that the record-playback switch is very dirty inside.

If you are lucky, 'exercising' it will clean it up and it will eventually start working normally, but usually a record-playback switch in that condition needs to be cleaned properly.
