Any tips on diagnosis?
To diagnose, you need to use any terminal program to see waht the empeg's start-up messages say. An easier alternative may be to give your empeg a fresh shot of 1.03. If the troubels are software related, and assuming your music databases are OK, the empeg should come to live *if* you can manage a software refresh.
If you can't reload 1.03, you may be in the deep trouble that you fear

.
I'd go for a software refresh, and if that fails, send support a boot-up log.
Bon courage
