I have a Mits model 55819 that just shut off for no apparent reason and will not turn back on. It is around 7 years old so since it is out of waaranty, I took the back panel off and looked for a blown fuse. The fuse was fine so I am in the "dark" as to what is wrong with it. I have been told it is a bad power supply. What I want to know is there some type of "reset" switch with this model. I do not see one in the front so is there somewhere else to look? Or is this truly a bad power supply?:wits-end: Please help!! Thanks, Bill.
