Hardware Errorcode 21SS/1/5: OX40



I can't get any sound on my Powerbook G4 and ran the hardware test after trying all the usual things. The error code was:

21SS/1/5: OX40 or 2ISS/1/5: OX40

Anyway, I've searched the internet and the forum and the only thing I seem to find is that error codes aren't available to the general public and you are the only guys who may have some clue!

I know I will probably have to take it to the repair shop but wonder whether anybody could tell me what the fault is and what I'm likely to be in to replacing (severely cash strapped after Christmas with 6 kids to buy for)!

Many thanks.
