Re: Yamaha RX-V3900
Did you check the output voltages on the DCCNVT pcb?
I had an issue with the board, Channel 2 4.3v Dc. Rail was < 0.4VDC.
This was triggering the protect mode.
Note: During this fault you could not enter diagnostics mode, but could activate PSU’s to test voltages using the diag mode.
Replaced the DCCNVT board, problem resolved.
