Amp repair, Power Acoustik 840W Gothic

This is the older series amp, aluminum with the "chicken wire" on the sides. One of the Mossfets burned up in this amp. I replaced it yesterday and the amp is still not working right. When you power up the remote input, the amp goes to protect. It kicks off and on protect, never actually showing power. It kicks the subs every time the protect light flashes. Any ideas on what went wrong here? This is the same thing it did before the mossfet burned.

try removing your main diode packs ( remember what one goes where) then if it works it could be a problem in the amplifier side of the board

You said you replaced the bad mosfet? Was it a mosfet on the power supply or on the amplifier? If it was on the power supply you will have to change them all(on the power supply).Once one of them goes bad they all get damage.

The Mosfet I replaced was one of the smaller ones. I will have to look further into it to see which side it was on. I assume the power supply side would be towards the RCA inputs? Also, the diode packs? Where are these and what would they look like. Thanks to budd7566 and bdl666.
