denon double k7 deck drw580

Looking after the schematic diagram from Denon DRW580.

I would like to have the schematic from this set listed above, regarding the following failure.
That's impossible to get the play function about the left deck ,but the right deck works normally, (play, wind and rewind function). When i put left deck in play position, the relay suddenly release on, and go on many times, so it's impossible to keep it in the play position .
That is my probleme now, and i hope that, you could satisfy my request.

Thank you in advance, and best regards. Estripeaut Pierre
