mon ami, JJB Amiga Centre peut vous aider.
I do rate jaque's work as some of the finest available, although expensive, most of this cost is down to insured postage.
Unfortunately, if its a firmware fault then he might be the only person I know whom could help.
Bonne chance avec votre quête.

(yes I have been practicing french incase anyone is wondering =D)
