Hi everybody,
I've fixed the faulty mk3 by changing the cd drive. This way i could upload firmware V17 ad after that V22.1.

I've another similiar mk3 with the following problem:

The cd engine works and the power led is on but the display remains blank. If I try a software update cd the disc goes on spinning but notthing else happens. Any suggestions? (the cd drive is working well so that's not where the problem is)
