Unit blinking 888, won't turn on

The power went out at my apartment a few nights ago and now my cube just blinks 888 with all lights flashing whenever it's plugged in. I contacted the site help and they sent me a link to the Cube power supply repair kit and power replacement guide. Has anyone successfully done this? I tried calling around in my area but apparently no one does small appliance repair anymore. Am willing to try it but not sure I want to spend the money if it's hopeless.
