Philips Car Radio/Cassette Player 22AC804/22

[Katja D]

Hello

I'm looking for a downloadable schematic diagramm and/or some repair hints.

The box playes cassettes but not radio.

The cassette modul has an output signal indicating whether the cassette
is playing or not. I think (but doesn't know) that this signal isn't
evaluated by the radio/amplifier part.

Thanks Katja

P.S. please excuse my english - it's not my native language
