LCD stands for Liquid Crystal Display.  \nWhen you press the panel with your finger, you apply pressure to the liquid underneath.  Don't press too hard or you might break it.  :]\n\nI use one on my computer.

Your LCD screen is as sensitive as your eyeball. No harsh chemicals, no harsh abrasives.\n\nIf you think the screen is not that sensitive, press on the screen very gently with an index card and watch the screen display image start to distort. Again think eyeball while cleaning.\n\nI use distilled water and a soft cloth. \n\nIf this is a notebook don't mistake keyboard impressions as dust or grime. I have seen dozens of Dell and Apple notebook key images scored into the LCD screen. They can't be cleaned.

Most often this is caused by a bad video cable or connector.  Try tighting the video cable connectors at both ends.  If that doesn't work try wiggling the cable which some times works if the cable is shorting out.  If that's the case or there is no improvement, try replacing the video cable if it has connectors at both ends.  If it's an older display screen, the video cable may come out of the display screen chassis as a cable with no connector to the display.  If that's the case, then you may be out of luck because you won't be able to replace the cable.  You could try checking for bent pins in the connectors also, but these are hard to fix.  Bottom line, it's probably your cable, tighten it down at the connectors to see if that helps, if not replace cable, if display is old and cable can't be replaced, time to buy a new display!  Good luck!

that sounds like a problem with your computer screen. the colors change when the monitor is about to stop working

disconect the monitor cable from the video card and look at the pins....make sure one didn't get bent. it's way easy to bend one and it will usually throw off the color or brighrness. if thats ok, try adjusting the brightness and contrast on the monitor.

I need feedback on this.\n\nChange the screen resolution.  \nDo the circles disappear, shrink or enlarge?\nAre they graphics or are they there even when the monitor is off?

the newer lcd's are much tougher than the original ones. before, lcd technology was based on gases filling compartments. touching the screen could damage the compartments. nowadays, the material used to make the compartments is much stronger and resilient (and much faster) than before.\n\nimho, treat it like you would glass, but not like tile.

You can change the contrast and other settings in your display settings. There should be a advanced button located in that option.

if the monitor stays on, but the lcd isn't, then go into the bios settings, it is set to crt only maybe, then there should be a func key to switch it back and forth, have found that to be the problem also

Hello. I have had the same problem with my Dell 15" LCD. I don't know what happened when suddenly I'm playing a game and I'm thinking that the game's graphics are awesome because its raining and the thunder really lights up the screen. Then I realize that my pixels are fading, exactly how you described it. I tried unplugging everything and replugging it in again, but nothing seemed to work. I decided to go back to my old CRT monitor and for a few months that worked fine. As luck would have it, it broke as well. I decided to test my LCD again, and to my surprise, it worked now. After about two weeks, I unplugged everything because I was moving my computer to another room. When everything was replugged, the same problem plagued my monitor. That's when I've had enough. I called Dell Customer Service, which was really helpful, and they offered to replace my monitor with a new one even though it was out of warranty. I don't if there is maybe something wrong with the entire line of Dell monitors, but they sure were helpful and considerate. Of course you have to send back your old monitor, but they picked it up from my house and paid for the shipping costs as well.

Your monitor probably has buttons on the front of it for controling the brightness and contrast, and it sounds like those buttons are starting to wear out and "push" themselves. You could take it to a computer shop and get it fixed (they can replace the buttons), but if it's an old monitor, you're probably better off getting a new one.

Yes it can be done, acutally that is the basic working principal of a  LCD, but the clarity of the image is not so good

i've had that happening while typing its probably dust blowing onto the censor pad causing enough pressure to read as a finger print, ive also had it with a P.C. it could just be the page your using, if it happens constantly on one page try using a different page if not try to keep your mouse/censor pad clear of dirt

There are several componants that could be going bad.\nThe most likely is the red output transister, or it's associated circuitry.  If you have a CRT type monitor, it could be a problem in the picture tube.\nIt would probably be cheaper to replace it than to get it fixed.

When you press "Print Screen," what happens? Does it just not work, or the graphics are messed up, what?\n\nTry restarting your computer if it just doesn't take a screen shot, sometimes that happens to me when I try to take a screen shot. I don't know why that happens, but the computer just stops taking screen shots after taking a couple already.

That is probably a dead pixel. This could make it worse or it could fix it, Push on the spot, Then turn on the tv. Try at your own risk! It worked for me.

I have fixed the problem before changing the lithium battery.  That would be the next guess since you tried to adjust the contrast.\n\nThe next step may be checking with the manufacturer
