I am assuming your power cord and outlet are good. In that case, there is a fuse protection circuit that will not let your main unit turn on if the fuse is open, or bad. After the electricity goes through the fuse, it turns on a relay, which then turns on the unit. You have to take the unit apart to get to it, and check it with an ohmmeter (part of a voltmeter), but make sure the unit is UNPLUGGED before you do that, please! If you can see any cracked solder joints, you can resolder them, but that is about all you can try, without having it repaired at a shop. Good luck, and hope this helps.
