Hello all. Last time i had a problem with a fender amp, i was able to fix it with help from members here. Hoping I can fix this amp as well. It is a fender rumble 100. The only schematics i have been able to find are here.

So when i plug it in, the two red led's just flash and I get no sound. I did not have much time last night, but was able to at least put a meter on VDD and VSS which are supposed to be 24 and -24 Volts. With the rear I/O board unplugged was was measuring about 16V and -16Volts. When I plug the I/O board in, it measures at 3 and -3 volts. Just wondering where to even start. Any help would be appreciated.
thanks!
