@@juansneider RCF wouldn't give me schematics or parts even though I was authorised in Brazil at the time. The customer put live 220v voltage on the earth and fried e erything on the board.
Did you manage to fix these? For the ones with no audio it's more than likely an issue with the DAC IC ADAU1701. For the one with no power, most common fried parts are 1BW Transistor, S21531D Driver IC, and the 6R190C6 N-Channel Mosfets.

No, I haven't fixed them yet. The live wire shorted to the earth in the PCon connector; everything connected to earth may be fried. I have got an AD convertor so I may try to fix one. Thanks for your suggestions, I'll let you know if I get any results.
Hello,nice videos,i have opened a RCF ART 715 module and DC voltage (75 Volts) is present on High Frequency Driver output What do you think it is causing this problem ?
Hi, i have One of this broken, i need to know what are the ic ‘s if you have some schemetixs please help me
