Hi all,

my beosound 9000 was broken. No standby light, nothing.

I found out that the pcb 43 powersupply was defective.

so I replaced it with a used one.

after that standby light comes back. I did the testmodes for cd drive, everthing ok.

now my Problem is.

I can use the cd without any Problem. I can choose A.Aux no probs.

But Icannot choose the Radio. If I try the 9000 shut down and comes back to the standby Modus about 2-3 seconds later.

I don´t think it is the Radio platine, because I tried two different of them.

Testmode 27 Shows IIC error 98

I can not use specific testmodes for Radio. Same Procedere, 9000 shut down

maybe someone of you has some ideas for me.

Thank you Markus

Next I found out is when i disconnect the tuner testmode 27 Shows error IIC 102.

really nobody any idears?

Would be really sad to use this one as sparepart, because it‘s in Perfect condition.

new Laser, new Glas and new Front Panels.

all other Thinge work Perfect.

only the Radio isn‘t working. Should I tre to her another Tuner Platine?

I fixend the problem myself.

on my beosound 9000 it was a shortcut on pcb 34 near point p3

and a damaged ic 7

took me hours to find. But now works like a charme 

maybe you can send me very detailed fotos from the backside of your pcb34
