Good afternoon to everyone.
I also have some issues with my DIGIPRO 600M amplifier. 
Can I receive the electrical schema?

Many thanks,
Matteo Falchi

Hi, who's successfully repaired Digipro modules ?
I've got a digipro1000 on the bench at the moment, SMPS is GOOD, Output FETs are GOOD.
Won't start with the O/P FETs in, No swithching waveforms on the FET gates on either channel.
I'm about to replace the IRS20957S drivers but seems a bit odd that i'm getting nothing on both channels, so its possible the shutdown is active.
LED 1 and 2 are lit, but their function is not labelled on the board or schematic.

any help apreciated :-)
