I have the same problem and although I haven't actually solved it yet, upon disassembly of the product (mitsubishi wt-42311) i saw dark spots on the power distribution board, (the one the cord plugs into), in about the middle of the board. this is a sign of a burnt component due to an overload or short. I also noticed a crack in the board(more visible from the bottom side) right around the main power relay (the thing that goes click when you turn it on). I am looking for a new power dis board to see if this helps. If anyone knows where I can get one affordably please let me know. My e-mail is mrmotormd@hotmail/yahoo.com. hotmail or yahoo works for me and any information you can offer would be greatly appreciated.
