Does the LED lamp flash on the start button? It sounds like you may have the same problem as me. Apparently the flashing green LED lamp that flashes corespond to some sort of code, depending how many times it flashes. Mine is F:7 (7 flashes). If it does flash and you find what the code is you can determine the problem. I am waiting to see if anyone can tell me what F: 7 coresponds to.
