If you'd like, I can take a look at it. Admittedly, monitor/tv's and I don't get along too well - I bat about 50% repair rate, but I can take a stab at it for you.

It is indeed PWM. I got out my oscilliscope and checked it, and here are the results I got: At setting 1 (closest to off): Th: 1ms Tl: 2ms Tt: 3ms 9Vpp At setting 2: Th: 2ms Tl: 1ms Tt: 3ms 9Vpp And at full on, it's just 9v DC. (...) (22 years ago, 29-Dec-02, to lugnet.org.ca.rtltoronto)
