EV Evolve 50 no sound from any input.

[Rotorcraft230]

So I usually only work on guitar tube amps but a friend ask if I could look at his EV Evolve 50. It has no sound coming out if it from any input. I'm assuming it's a power amp problem. The unit power up, I did pull the amp out slightly and did see some LEDs lit up.

Aux15v on. Lit
SMPS. Lit
Amp on. Lit

Don't know where to start!!

I did have something odd, the large cap 220uf 450v had 66VAC AND 52 VDC on the top exposed part where the expansion lines are.

I'm going to post this and figure out how to post pictures.

Thanks
