HELP w Esoteric K-01

Last night during the storm I had a couple of surges and lights flickering, my system shut down (just as it has done in the past). But now the Esoteric K-01 turns on but then turns off. The on button stays lit up but the display screen goes blank. i have unplugged the system and let it sit, then try again, but same thing. The owner's manual doesn't address anything like this in the "trouble shooting" section. There appears to be no fuse and this doesn't seem to be a fuse issue. Any suggestions?
thank you.
