Uh-oh...
I was just running my set for about 10 minutes and while I was adjusting the bulls-eye tuning a bit, I started to notice this little "hiss" coming from inside my set. I hadn't ever heard that before. Awhile awhile, it started to get louder. I turn my brightest up and the sound get's a bit quieter, but if I turn it lower the sound get's louder. I'm almost certain it's coming from the high voltage cage. Smells like... static electricity.
As much as I hate to ask, can a failing flyback cause contrast problems?
