Despite my best efforts, I'm getting pushed into more and more of this kind of work, and I hate lighting work.
Anyway, for a long time, I've managed to avoid working on this crap, but I've been getting more and more of it lately.
I'm looking for some solid troubleshooting info for electronic ballasts and the like.
I'm tired of the method that I've been using which amounts to trial and error. Change this part, change that part, change all the parts and hope for the best.
