I have a WS-55907 that will not turn on at all. When I plug it into the wall it sounds like it is getting power. Checked the fuse at the power cord and it is good. Any suggestions?
Same problem and Just had repair man out. Said it was the signal board and that with this model it is a very common problem. Mitsubishi no longer makes the parts to fix it. If you want to scout online for one th product number for a signal board is 930b868003
If it is clicking you need to check the power Circuits both switched and un-switched. If I had to guess you have lost you 24pos or negative voltage. both circuits have a diode and a fuse on the board that need to be checked. If the diode is bad you must replace it the the same Ultra High speed type.
