Sharp AR-207

Question

On Wed. I used the machine and it seemed just fine.  I turned it off and left it off all night then on Thursday morning I powered it up, it came on and went through it's warm up routine?, and then it powered itself down and will not power back on.  I have changed the power source to no avail even though the two (2) other items plugged into the surge protector never stopped working or lost power.  Is there some kind of fuse that may have blown in the machine or perhaps a reset button?
