When you scroll down the screen on the monitor it takes ages as it flickers through each line

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

if rebooting the monitor would do no good, try to get a spare monitor cable if the same flickering issue took effect. If it is so, then call your pc provider to repair your monitor..

screen is going bad which is why its flickering and has the lines across the screen. Theres a board behind the lcd and when that doesn't process the voltage properly it can cause the screen to flicker. White lines across the screen means the screen is going bad. At this point unless your monitor is under warranty, go ahead and replace it.

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.

could be fixed by ajdusting the refresh rate....

you could try this (xp pro sp2)

please rate if useful, good luck

Open Display in Control Panel.
On the Settings tab, click Advanced.
On the Monitor tab, in the Refresh Frequency list, click a new refresh rate.

To open Display, click Start, click Control Panel, click Appearance and Themes, and then click Display.

• The default refresh frequency setting is 100 Hertz, although your monitor may support a higher setting. Check your manufacturer's documentation for information regarding the settings your monitor supports.
• A higher refresh frequency reduces any flicker on your screen, but choosing a setting that is too high for your monitor can make your display unusable and cause damage to your hardware.
• Changes to the refresh frequency affect all users that log on to the computer.

Have you tryed unpluging then pluging your video cables? or something?

To determine if he video card is faulty, connect an external monitor to the laptop's external video port, then power up the external monitor and then the laptop. The video info should automaticall switch to the external monitor. If you see anormal Windows image on the monitor then the video card is OK and the fault is with the LCD screen, could be the video cable/connector. Try reseating the video cable/connector to the motherboard.
If the video card is faulty and because it is part of the motherboard it is extremely dificult to repair, usually a replacement motherboard is required. This may not be a cost effective solution depending the age of the laptop. You could remove the hard drive from this laptop and insert it into an USB hard drive adapter case and use it as an external USB drive.

MONITOR ABCs
The monitor is a hardware device which physically connects to your video card. The monitor allows information and current status be be visually outputted similar to a TV.
Like most TVs, the computer monitor has a CRT, or Cathode Ray Tube, which is found inside the computer monitor as illustrated in the above picture. The CRT is the main component and most expensive part within your computer monitor. Within the CRT are three electron guns, Red, Green and Blue. Each of these guns streams a steady flow of electrons, left to right, for each line of your monitor. As the electrons hit the phosphors on the CRT, the phosphor will glow certain intensities. As a new line begins, the guns will then begin at the left and continue right; these guns will repeat this process sometimes thousands of times until the screen has been completely drawn line by line. Once the phosphors on the CRT have been hit with an electron they will only glow for a short period of time; because of this, the CRT must be refreshed, which means the process will be repeated as explained above. If the video card's refresh rate is not set high enough, you may encounter a flicker or a noticeable steady line scrolling from the top to the bottom of your screen. If you are encountering this issue, resolutions have been described on our video card page.

MINIMUM RESOLUTION The size is an important factor of the computer's running resolution. When picking the resolution, try basing it off the monitor's size for best use. 13-inch 640 x 480 15-inch 800 x 600 17-inch 1,024 x 768 21-inch 1,280 x 1,024


Hope this works for ya/Please dont for get to vote.

The high voltage (HV) flyback transformer is a very possible cause of this. This could be repaired by a qualified technician, but the cost may not be worth it. New 17" monitors can be acquired for free sometimes (think craigslist)
