Question about Mosfet
I can replace the FDA24N40F with the IRFP360 as I currently do not have those mosfets and would like to resolve it soon

Is it worth the risk?
If it comes back with more damage (to the PS?), who pays for the parts and labor?
I'm assuming that this is for someone else.

Well, in the end I managed to get the parts from a local store, however the amp is muted, when putting the load on a speaker it starts to oscillate, but I still don't get any audio on the output and if I press the master slave button it only gets hear a bang this every time I press it
Post a good quality photo of the component side of the entire main board and the component side of any driver boards if no one can help.
good morning Perry
check the voltages on the class d card and they are present at +5 -5, the audio signal does not arrive at pin5 of the central header you will have a diagram close enough to track the audio signal or any suggestion of where to check

I really have nothing the ZNCM amps. The following thread is what I use for the driver board. There are several diagrams, use the last one.

those pots are extremely dirty. Can you post a full photo of the board? I don't recognize the vertical inductors and can not see them on any xfire amps I searched for. The card if in question has been replicated by a couple people but AlbertLeRoux can help if you need a new one, also believe AmpLab has them as well however they are both in the US.
Good afternoon
I am taking this amplifier again and I don't think the problem is the card since the amplifier is oscillating correctly, sorry for my English but the problem is that the audio does not reach pin 5 of the bd card, I found the integrated one marked in blue in the image that did not work I changed it and the audio reaches the other two operations that are in green but still does not reach pin 5 of the middle pin board
