SOURCE: ACER LCD monitor no image, appears white color only

Quickly go to the Acer website and check FAQ's and while there also find out how to get an RMA to return it. My guess is you have a bad monitor. At $200 roughly for a replacement I would hustle. I am assuming you got nothing but a white screen but did get video on your TV.

SOURCE: screen flickers for about 20-30 seconds sporadically

Try looking at the LCD screen at a sharp angle to see if ghost-like video can be seen during the 'off' time of the flicker.  If video is still present even though not that visible, then either the backlight or its power supply are failing. The color problem could also be caused by a backlight lamp that is not ionizing completely.

SOURCE: Magenta vertical stripe sets plus grid dots problem

Staples office supply store said it was the monitor and, after buying and installing a new $200 monitor, I discovered it wasn't the monitor. I brought my hard drive to a reputable computer repair place, who charged me $50 total to install a new video card. He also supped up my hard drive with an additional 512K ram for $20 and now things are so much better. You were right! It was the video card.

Any of the 3 internal wires that delivers the tree color (Reg-Grenn-Blue) is disconected or damaged.

Open your monitor and try to locate that wires...

Good Luck

Best Regards !

SOURCE: Monitor colors are not displaying correctly

Hi, At the worst it is a blown monitor, but have hope. 1st try a new or known good lead, between monitor and PC. 2nd put monitor with own lead on good PC. if 1st works = result. if 2nd and monitor is same, suspect monitor, however, if 2nd works ok on other PC, then look at ur vid card. Either way, this test sequence should save you some $. Be lucky.

My dell 1201 projectors displays only in yellow


you have most likely lost 2 of your color guns, most projectors have RED, Green and BLUE as the projector colors (some newer projectors have added a 4th color). if one of your color guns has gone out, you may experience colors that are not correct. that is where I would start. go to the convergence routine, in your setup menu. this is where you can determine if one of your "guns" has quit working.

My monitor turns yellowish i can still work what is the problem. the monitor is a Acer V233H


The red "gun" of your CRT monitor is going bad. You will need to get a new monitor, and you should seriously consider an LCD flat screen. It will save you allot in electricity.

A CRT monitor is a very cool piece of technology inside... even though they are going obsolete with the advent of modern LCD displays.

In every CRT (Cathode Ray Tube) monitor, there is a trio of "Electron Guns"- they fire electrons at the front of the screen, hitting it with billions upon billions of electrons... the "bullets". Each gun is aimed at a set of colored targets, called "pixels"... one gun hits red ones, one for green, and one for blue. Combinations of these colors make up everything we can see.

When the red "gun" cannot fire enough electron "bullets" at the screen, the blue and green together make the picture appear yellowish.

If you want to learn more, look up "cathode ray tube" on wikipedia for starters!

A word of warning- the technology is very cool (I used to teach how CRT screens worked as part of my job teaching Missile fire control radar for the Navy), BUT:

THERE ARE VERY HIGH VOLTAGES INSIDE A CRT MONITOR THAT CAN KILL!!! DO NOT OPEN
THE CASE!!!!

Remember- the electron "guns" inside are shooting billions and billions of electrons at the front of the screen. They are being collected from the screen by a high voltage "supply". Most CRT's operate with anywhere from 15 to 45 THOUSAND VOLTS!

MY MONITER CHANGES COLOR AND ITS PISSING ME OFF HOW CAN I DO IT. IT ALWAYS CHANGES COLOR MOST OF THE TIME IT CHANGES TO RED COLOR


One or two of your color guns are failing. On a CRT, there are three color guns, Red, Green, Blue. They work together to produce all colors in the spectrum. If the monitor goes all one color, it generally means at least one color gun is failing. The cost to repair far exceeds the value of the monitor or the price of a new LCD panel.

Red color missing in LCD monitor


if under warranty contact the manufacturer for repairs. otherwise you'd be in the market for a new monitor.

Also check your graphics card. Might be causing the problem rather than your monitor.
