Adcom Preamp Issue

Hello,

looking for advice for a recent issue with my Adcom GFP-750 preamp. When I turn the power on, the front indicator lights briefly come on (less than a second) and then the unit shuts off. I've removed the cover and nothing visibly looks damaged, fwiw. I've checked resistance on the 3 fuses and they're all ok. Not sure where to go from there. Any help is appreciated!
