If "R/P WHICH?" appears, the mechanism and the PWB can be mismatched. Check whether the combination of the playing/
recording PWB and mechanism are appropriate.
If "R/P WHICH?" still appears, eject the disc and check as follows.
Check 1: Check the pin 100 line of IC1401 for defective soldering. Check the pin 93 line of IC1401 for short-circuit and defective
recording PWB and mechanism are appropriate.
