Blown Beomaster 6500

I'm using TP2 for the Tape as I have a Sony minidisc in TP1. I noticed that TP1 and CD datalinks are paired.

Not sure if this makes a difference.

Swopped TP1 and TP2 over and I can no longer operate the Beocord so it looks like the datalink diodes on TP1 and CD as Martin suggested.

This may take a while, anyone know the values of D3 and D4 ? Being a complete novice I have no idea 

They are both 1N4148

Having finally got a working BM7000 I've been reluctant to dismantle it again but today I took the plunge and replaced diodes 3 and 4 on the CD and TP1 data circuit, (anyone whose done this know what a pain in the bum it is !).

Still can't remotely operate the CD or TP1, phono and TP2 still work grrrrr, any more ideas ??

Capacitor C16 on the microprocessor board maybe ?

All 7 pins present in the DIN plugs of the CD/Tape products you are connecting?

Martin

Yes, and they have worked for years before the BM6500 went wrong. The remote operates the cassette if it's in TP2 but not in TP1.
