    One time I had a problem with a 40w power supply. The tube wouldn't light and I knew it was still good. I took the power supply apart and noticed one of the bolts holding the high power transformer in place was broken. Apparently the transformer was only grounded through this bolt. I managed to solder a connection (don't ask me how- it was ugly) and brought the power supply back to life. If you have good electronic skillz, check it out. It could be something really stupid.
