I don't know your level of experience, but I will give you some basic ideas where to look...Have you opened the case and checked to see if the board fuse has blown? I know, thats a simple question, but sometimes there is a second board mounted fuse. Another thing, try a different outlet....have you checked the power supply to see if 1) it is receiving voltage, 2) is it coming out the other side...and are there any broken resisitors, triacs, regulators etc...did it smell burnt at all? I would take it apart, get a bright flashlight shining on the board and just stare at it and look at a 4" square at a time to just look for something that doesnt look right. Its the little things that need to be checked along with some obvious...If its not visual, it very well could be just a failed piece of the boards components that didn't fry, but it tripped the protection circuit..for your benefit...Good Luck...
