    info662, Did you try some simple things as moving it to another PC? Have you noticed if the screen kinda flickers as when you turn on one of those new curlie-que screw-in energy saving light bulbs? The same technology is used to light-up your LCD/FPD. Your display seems to have either weak or failing 'cold cathode Fluorescent tubes, and/or an INVERTER power supply that is slowly walking to the graveyard. It could also be that the inverter board has developed cold solder joints and possibly some electrolytic filter capacitors have failed, and the board cannot supply full voltage to the CCFtubes. HELLO!!! Fooling around with the ADJ. buttons will not help you out!! You will need to find out if there is a swapout program frm Westinghouse where you send cash and old monitor, and they send you a REFURBISHED replacement. Or Find local TV/Monitor repair shop that knows all there is to know about CCF tube replacement/ inverter/power supply rebuilding/repair. Yes, I have "lucked-Out' in finding bad capacitors in these types of monitors. replaced them and now the monitor works great. I'm louie12fix at fixya or lmistyrel @ aol.com Hope this info was of some use. BYE

SOURCE: Flickeing like a dying fluorescent light bulb

Actually this is a 'warning' signal from your lcd monitor. The problem is your lcd ccfl lamp are near to their life, need to change. The ccfl lamp like our home fluorescent lamp, when the lamp need to dead, the lamp will flickering first, after some time, will totally off(dead). So, this is a signal for you. Some lcd monitor, when their inverter board are using fairchild inverter ic(oz series), will easily shutdown your monitor when they detected some flickering on your screen (ccfl lamp). If you need more information on repair your lcd monitor please visit http://www.fastrepairguide.com . Thanks.

SOURCE: Dell 2005FPW Monitor Flicker problem

The flickering is most likely the florescent backlight having a hard time starting, Just like in a light fixture, as it gets old, it takes longer to warm up to get full functionality.
If under warranty, contact Dell for a replacement, if not, then when it becomes untenable, replace the monitor. Prices are dropping drastically, an new 20 or 22 In can be bought for about $150 or less

Basic "background" colors are wrong:


Kathy...have you tried connecting another monitor to the same video card and computer? It could be...

1. Video card defective
2. VGA cable from computer to monitor defective...look for bent pins in plug.

The VGA cable from the computer video output carries three distinct colors...red, green and blue. Likewise one of these colors may not arrive at the monitor correctly or at all. The results being that all colors are incorrect.

Monitor flickers, similar to a fluorescent light bulb that is going out. Also, there is one line on the left side of the screen, going up and down, that changes color, but it comes and goes. I thought...


The problem is in the monitor screen, there is a large circuit board connected behind the main display screen. The video signal is feed to the main board and generates the proper color balance, the second problem is the lamp behind the display is flickering and breaking down. To repair this will not be cost effective, cheaper to replace the monitor. But I would suggest hooking a spare monitor to the computer to make sure there are no additional issues.

When the computer comes on the monitor will not connect. The indicator light flickers an orange color. Sometime if I unplug the monitor cable it will come on.


your cable can be broken or your video board may be broken...first try with another cable, if this not solves the problem try with another monitor, and if still doesn't work that means your video board has a problem

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.
