When plugged in, or push the power button on, the fan underneath comes on for about 3 seconds. I might hear something shift about 30 seconds later, but nothing else. No lights, no lcd, no compressor, nothing. The parts list show two control boards, and a power module. I cant find the paper schematics anywhere to find out what I can test. When I push the power button inside, I have juice to power boards (only testing with a noncontact since I dont know what legs to test, but still nothing comes on.)
