Hi guys! I got another M90. After a lot of work, I managed to get it working, I changed the standard fusible resistors, belts, cleaned and lubricated, and also replaced the audio amplifier chip. Now the radio is working, but there are a few problems left:
1. If you press the "play" button and then press rewind (regardless of whether it is forward or backward), the sound does not disappear during rewind and the accelerated sound still sounds loudly from the speakers, as when playing.
2. Auto search for songs does not work. I can choose how many tracks to rewind, the LEDs are lit, but when rewind is turned on, the deck rewinds the entire tape, as if the system does not see that one song has ended and the next one has begun.
Perhaps these are related problems? I haven't come across this before, so I'm asking for your help. Thanks in advance. Take care of yourself!
