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 :-)

Yes, I can fix your amp, even if pic16f689 is damaged. 7 blinks means that adau not loaded from eeprom or damaged

I'm from Russia, Tver. I think the shipping cost will be too much.
