Is this a CRT or LCD? Assuming it's a CRT, usually on the PCB on the CRT neck/yoke, there are RGB adjustments.
I CANNOT EMPHASIZE ENOUGH the following: UNPLUG the monitor and LEAVE IT unplugged for several days. The caps (capacitors) can and WILL retain a charge for even weeks, and they can and will hold the charge for the flyback which can be 20-40,000 volts and even higher, if you should happen to touch anything in that area. Wear RUBBER GLOVES that have a dielectric high enough to insulate against this type of voltage. Then, search for the pots. Usually the pots can be adjusted with fingers, but if not, DO NOT use a metal screwdriver, use a plastic one or make one out of something wooden. Once you have them located, you'll have to turn the monitor back on and somehow SAFELY as I suggested, adjust the pots. I've been shocked numerous times over the years still even following safe guidelines, because sometimes you can and will "slip" and touch something that is holding a high residual charge. Since white is "white", then they should not need adjustment and it may not help. If you adjust so gray is gray, white may no longer be white. Best thing is a CRT test pattern. Some monitor manufacturers offer these, if not you can search and maybe find one you can download. It also could need a CRT booster to fix the problem, or the power supply could be "going down" a bit. -Clint God Bless Clint Hamilton, Owner http://OrpheusComputing.com ) ----- Original Message ----- From: <[EMAIL PROTECTED]> I have a KDS KD-5250 15" monitor which does not display the colors properly. When white is required, the three color guns are full on and white is displayed. This is as it should be. When shades of gray are required, each color gun should reduce its intensity in such a manner that the brightness of each color phosphor decreases an equal amount. This produces darker shades of gray. The green gun does not reduce its intensity as much as the red and blue guns which results in a dark green field instead of a gray field. There are no external adjustments for color balance. Does anyone have any suggestions concerning what internal adjustments can be made to the separate color gun amplifiers in order to correct this problem? I have not as yet opened the monitor case so I have no idea what adjustments are available in this monitor. Wally ============= PCWorks Mailing List ================= Don't see your post?
