I have a Hanns-G HW191D 19' I've had it for about a 2-3 years and now its starts to develop this annoying problem. After about 1-2 hours the back light starts flicker between full brightness and ever so slightly dimmer. I was wondering if anyone had any similar problems with LCD monitors, and how to possible solve it. I'm not scared of opening it up and fiddling around with it.
