Dead M70

Hey, yesterday my M70 arrived, after cleaning I saw that the right VU Level is lower then the Left, both Channels had the same volume and it was not only when i played a tape, at recording Mode both VUs work fine, and Tuning and Battery Check works, too. The Autostop also didn't work so I took the tape unit and tried to fix it, after 5 tries the autostop worked, but when i pressed play the sixth time the motor didn't turn on anymore and now there's no dial light, no power LED and no Tape plays, i can only hear the hiss of the tape head. Radio works, VU's and Aux, too. On the motor is only a low voltage about 2 Volts or less.

When I plug out the tapedeck the Light and the Power LED doesn't work so it can't be a problem of the tape, I'd say I shot down a transistor or a diode on the mainboard.

How can I repair this? Does anyone know what that could be? How can I fix up the VU to show both the same level at playback mode?

Ich schätze, der Schalt-Kontakt für dein Motor ist oxidiert. Diese Schließkontakt ist irgendwo an der Laufwerksmechanik und wird bei jeder Laufwerksfunktion betätigt.

Loosely translated:

I estimate, which is switching contact for your engine oxidized. This closing contact is at the drive assembly mechanics and with each drive assembly function is somewhere operated.

but then the power LED and the Dial Light would work if i switch to radio.
