Good afternoon gentlemen, I have on my table a hifonics brutus amplifier, it already came from another repair shop, replace source and output mosfets (irf3205 and irf3710), as well as replace the hip4080 driver, the amplifier turns on, green light, there is no overconsumption , the problem is that there is no sound, the relay does not activate, and even by bridging the relay I have no sound, any idea where to start looking? Thanks in advance.
3710 or 3710Z?

The non-Z version can (and generally does) cause problems.
Do you have rail-rail oscillation on the output transistors?

neither side has oscillation, I noticed that the relay activates after 30 seconds but remains the same, there is no sound.
