Peavey XR 1600D powered mixer no output

Fixing to break into this thing. Any heads up on what the problem (or IC) causing this prob would be appreciated.

Be more specific. No output to speakers, but output OK to line outs and sends? No out at all anywhere? ANything happen if you feed the power amp in jacks, upper right? How about the main outs, the graphic ins and outs, the monitor outs and headphones? ANy of them work?

Aside from interconections and cutout jacks, you could have: blown power amp, blown internal fuses, missing power supply voltages, bad op amp in some buffer stage, connector off bewteen subassemblies, etc etc.

Sorry, Got in a hurry with my post.
No output through the speakers. Main, Monitors,graphs and phones are all ok.
Nothing on the power amp in.
Customer said it made a squeal and died. Was wondering if this was caused by a regular problem with this model.

If the power amp in jacks are not responsive, then the power amps are not running. If there are two dead power amps, that tends to mean to me something they have in common is bad, most likely powr supply.

I own a XR1600D and happened the same to me once. I could fix it replacing an internal fuse that it was burned out.
