Some issue with how the lamp is burning.

Why did it take me over a year to phone in a problem to ATT?

Flickering is usually caused by an old (or very cold) inverter and CCFL tube. If it's just cold, it should stabilize after a few minutes.

However, what you may be seeing is pixel jitter, which has nothing to do with the backlight. If the monitor only "flickers" when it displays a certain image or pattern, then it's pixel jitter. As far as I know, jitter only affects analog (VGA) panels; I've never seen a jittering digital panel. It can sometimes be prevented by using a better VGA cable, if DVI/HDMI/DP is unavailable.
