I have had my Maxstar 150 STH for many years and it has worked great. When I tried to turn it on yesterday nothing happened. I have checked the voltage before and after the switch and it is running around 119V-120V. I can't see any burnt contacts or solder joints and I cleaned all the plugs. I have zero voltage on the white wires going into the display board. It was working fine the last time I used it but it has been sitting for awhile.
