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
