    I have several Dell 21" P1110 monitors that I have repaired for excessive
    brightness. However, two of these monitors still take over 60 seconds to
    warm up and display a picture. Does anyone know how to speed up the warm up
    on these? Is this a power supply problem?

    Have you checked the CRT heater voltage ?
    I had a couple of Dell/Sony's where the electrolytic
    capacitor in the heater supply decreased in value
    causing low heater voltage or long warmups.
