Re: Compaq P1220

If that monitor is out of warranty, it's pretty much a throw away item. If you can find a "donor" monitor with a cracked CRT or case, you could probably swap the high voltage units and get it going again.

22 samsung syncmaster S22B150 led monitor color settings problem how to fix

I have the same monitor. It was working just fine for almost a full year and recently I started to play games on Furg Games Play Free Online Games for a few hours a day and my eyes started to hurt. I've tried to change brightness and contrast several times but still I can't stay more than an hour in front of it.

I have an HP 2310m monitor- 2 months old that has started to flicker and roll and then finally goes black. I have tried unplugging and that worked for about 4 days with no problems and then it started...

If the monitor is still under warranty you should consider take it in where it was bought, they will attempt to repair it, and given the choice I would opt to go that way simply because your monitor has several issues.

Monitor moving on its own

On your physical monitor adjust the verticle and horizontal lengths to take up the full length of the screen. The CRT guns have to draw the exact location of your screen, so extending them to the edges will be easier on the guns. You can also try raising the refresh rate, although that probably wont fix it but it will help on your eyes. and if You have other options like convergence, focus, etc. Try messing with those.

Brightness Problem


Since focus adjustment using the flyback rear controls (EHT) has no effect, then it could possible mean two things:
  • the EHT is defective (most likely) at least the controls; or
  • the picture tube is already weak.
A workaround is to replace the filter capacitor of the ~70V leading to the collector voltage of the 3 color drive transistor. Normally used to replace with is 100uF/160V.

Of course best would be to have the EHT checked/replaced.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Try the buttons on the front or side of the monitor to get to the menu using the + or - to maneuver Thu the menu items until you see the "sun" that's for brightness the half filled circle is for contrast that helps too.

Shows half screen only!

if you can't expand your screen size from the pulldown menu or vertically or horizontally center the picture one or two of the centering coils could be partially burned out. the monitor uses electromagnets around the crt neck to center the picture. varying the center controls apply or take away voltage from the coils to center the image. may be time for a new monitor
