Fixing color on moitor

SOURCE: dim compaq s510 crt colored monitor

Hi, If you are comfortable working with tools, down to component level and know how to work around EHV areas, then it is possible to increase the brightness of any monitor including the Compaq S510. Make sure that the unit is unplug, Open the back cover and locate the FBT. You have to run/power on/attach a running PC to the unit with the cover off. Extreme care must be exercised. If you are not sure, you're better off asking a qualified service professional to do the adjustment. There two plastic slotted adjustables, focus & screen. Adjusting the screen changes the screen voltage going to the CRT. This will make the display go very dark or overly too bright. Adjust to your preference (not necessarily technically correct) The focus may also be adjusted this way. You have to run the unit with the back cover open for a couple of minutes to stabilize the voltages and the heater/CRT/ Adjust after a couple of minutes if necessary. In other monitors, there is a trimpot (small variable resistor) the adjusts the sub-bright. Further improvement maybe achieved by adding a 100uF/250V capacitor across the supply of the 70+VDC of the 3 gun transistors. If you are sure how to go about this, it is best to consult or seek the services of a qualified TV technician who can either show where and how or do the job himself. Hope this be of some help to you. Pls post again how things turn up. Good luck and kind regards.

Have you tried using the Degauss option?

Press the Menu button on your Monitor and go to the Special Section. You should be able to find the degauss option there. Not sure it will work but its worth a try.

Check that the signal cable from the computer is firmly connected and that there are no bent pins in either end. If the trouble continues, the problem is in the monitor itself. Given the low replacement cost, it's uneconomical to try repairing these.
