Rockford fosgate punch 55.2 won't turn on

[chipper]

I have this punch 55.2 amp I'm working on I replaced the power supply fets and driver transistors. Amp still won't come on. Also removed all shorted outputs. No lights nothing, can anyone help me with this? Thanks

Board number is pc-1882-a

Anyone ? I just freshly replaced gate resistors, power supply mosfets (irf3205) and driver transistors. It's not coming on I'm not sure what to check next, any ideas??

Is the remote voltage making it through the amp?

I suppose, TL494 & LM339 get like warm. I don't get what's going on with this amp never experienced this problem usually I replace short semis and a few resistors and smd transistors and its working again but this one is something else...

Any possible way to check this w/o a meter? I left mine at my buddy's I have to go pick up it but for the mean time, I have a meter that measures continuity... TL494 & LM339 both get luke warm when I have power applied to the amp. No fets get warm or hot all stay cold.

I'll need the voltages on that IC to help.
