Default Behringer Eurolive B1800D Pro Amp turns on then off then on

Hello all, I recently picked this Eurolive 1800D pro for next to nothing and the problem is that it was going on then off then on through a continuous cycle, I've read another thread about the same thing and ended up being the bootstrapping capacitors, I was wondering if anyone could show me a picture or something that showed those capacitors or some places I could test to see if that's the problem or how to test the irs20957s, just need some ideas on where to start, thanks!

That means to me the SMPS is trying to start and something shuts it down when it does. My first reaction is check for a blown power amp output.

Can you tell us which power amp board is in this?
