Onborad channel fuses keeps blowing on Parasound 2205 AMP

I have a parasound 2205 amp and one channel is dead.I take it a part and the 2 fuses on channel 4 board are blown.

Now all the cap looks fine, the smaller ones and the 2 big 80v 15000uf.

So I replaced the 2 fuses and plug it in and the 2 fuses blew. This is with no pre amp plugged in and no speakers plugged in, just power.

I hate to send it out for repair since it will cost a ton for shipping and I'm not sure of any repair places locally to take it too.

I'm not bad at fixes thing and soldering components on the board.

So any thought if it could be one of the 2 large caps?

thanks for any directions.
