Default MPA died - reset?

My MPA was working fine for a long time, now the LED does not light on power-up and the unit is not working. I have verified that regulator is putting out 5V, and I see 5V on the inputs to the chips. Resistance across the pot output is ~100K.
Suggestions for troubleshooting? Is there a way to reset? I haven't loaded new firmware in some time, setup was working.
Is it possible to get a new CPU?

Hi Cliffman, welcome.

Sorry to hear about the problem. Please send an email that confirms your shipping address and I will send a replacement microcontroller for your MPA.
