Avant 12A

[rcm]

I have an Avant 12A amplifier which stops working; this has 3 board: IcePower50ASX2, IcePower125ASX2 and pcb: DSP PMS v1 0809, I have already changed the IcePower50ASX2, but It didn't work, and I'm that the same thing happens if I buy the IcePower125ASX2. I have checked the fuse, and they are ok. Can somebody help me fixing this amplifier? Thanks .

Hii we have maybe 10 pieces 125ASX2 maybe the same problem. One of my friend tool for checking parts I gave the amp cards to him. He told ICE marked IC short. If you check power supply, + rail drops. There is an aux supply working for ICE ic from + rail.
