    Default Fixing pale+fading LCD screens

    The title says it all; I have a Toshiba Satellite 2520 with a
    Enhanced STN color LCD display that is kinda pale. Is there
    any way to rejuvenate the screen?

    You sure it just isn't how the display is "supposed" to look? I remember old laptop LCDs being truly awful to use, even when relatively new, up until the P2 era.

    Likely the florescent tube is old or not getting enough power, for the back light. Do be careful the tubes use about 200-300 volts when lit. I've not see an easy source for these tubes.

    STN = passive matrix. They looked pale, ghosty, and smeary even when brand new. But people were willing to tolerate it because it was a lot cheaper than active matrix LCDs.

    If you need some 12" CFL backlight tubes, I may still have a few in my hellbox for a Compaq display that I never got around to refurbing.
