LCD monitor problem

I've had this issue off an on for a little while. The monitor is absolutely perfect, except when it comes to displaying dark black areas on screen. Then I periodically get vertical thin blue lines only in the black areas. No other graphix on screen get corrupted at all.. just the dark black areas. Sometimes these thin blue lines are long, sometimes very short, sometimes completely absent. I notice it mostly in gaming, running through dark cooridors. I also see it at its worst when I'm first turning on the computer, the boot up screen is all black with text.. and there are always thin blue lines running top to bottom, about a half inch apart, all the way across the display. This is on a XP Pro box.. with an ATI Radeon x850 card..

    I also have blue lines that appear at startup when the screen is black, also the focus is blurred. I've powered up the screen without powering up my desktop and the black screen has blue diagonal lines moving across the screen. My video card is also a Radeon X850. After a few minutes the blue lines disappear and the focus is sharp. This is however getting more severe as time goes by and it is taking longer for the blue lines to disappear and the focus to sharpen.

    Okay, I originally posted this problem.. and after much looking on the internet I came up with zero solutions. However, I managed to solve the problem myself. Whether this will work for anyone else remains to be seen.. but this worked for my monitor and a friend's monitor who was having the same issue.



    The solution? A slightly loose connection with the DVI connector into the back of the monitor. In other words, make sure that cable is seated nice and TIGHT. I was sitting there one day getting upset at the blue lines again, and decided to reach behind the monitor and wiggle the cable. Sure enough that made the blue lines jump a bit and then disappear completely. I was like, oh come on.. buuuut those lines have been totally absent for a year now.



    GIve it a shot.

    I've the same problem pretty much. It started with one thin vertical pink/purple line, but then another appeared in a different location and then another one. They don't seem to show over a cursor, are present at the computer start-up (although the most recent one blinks on/off then), and don't seem to respond to pressure.

    (This is on a laptop which has travelled in pretty rough conditions recently, so a loose connection sounds very likely.)

I have a LCD flat monitor and it has a black vertical band on the right side of the screen about 2 inches wide, which hides some of the texts of the web sites. Unable to fix it with the monitor screen control, the problem is obviously nmore complex. Please help.

Does it seem like it booted up all the way except the screen is black? If so try the steps below.

Shine a flashlight on the dark screen to see if you barelysee the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can beany kind of monitor even the old big fat crt monitors as long as it has a vgacable to connect to your computer's vga port. If so that proves yourvideo card is ok. The video will show on most systems when you rebootwithout you having to do anything. Some systems will require you to hit the FN(Function key) + F1 thru F12. Hold down the FN key then hit the correctkey for displaying on the monitor (F1 thru F12). The correct key willnormally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works,then your screen is bad. If you see no icons by shinning the flash lightand nothing shows on the external monitor, then most likely your video card isbad.

Asus crosshair socket am2 motherboard not booting


Sounds like your monitor is bad. Try another monitor because if the video card was bad and the monitor is working you would get a No Signal message on the screen. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor displays ok, then your original monitor is bad. If the Borrowed monitor does the same as your original monitor and does not display anything, then there is an issue with your video card.

You can look on eBay for BACKLIGHT FLUORESCENT BULB for your model.

They're around $20.00.

This is called a dark shading error. All the LCD consumer sets have some visible degree of this effect. Some will be a little less or more than others even from the same batch in the assembly run. This has to do with the optical design quality of how the back-plane lamps illuminate the screen. The design and assembly tollerance of this area is very critical.

Normally, LCD screens don't show their best picture in a darkened room. The very black regions of the picture content may look a little washed out. LCD screens are best watched in a room that is lit, but not very bright. You have to consider that there is a powerful set of lights behind the polarized panel of the LCD display, and there will always be some breakthrough of light.

If you want a TV that is more like a CRT in its characteristics a Plasma would have been a good choice. The trade-off with the Plasma is that it does not have the picture sharpness of the LCD. A Plasma set is best watched in a darkened room.

If you have an LCD computer monitor, take a look at it in a dark room with a black screen. You will most likely see the dark shading errors. Only the very expensive production studio type LCD monitors have less of this error than the consumer sets, and they are not absolutely perfect.

E173FP 17" LCD Monitor Problem


I have the same problem. It seems like a virus to me, but my anti-virus doesn't find anything. I went to the main menu on the moniter and changed the display time to five seconds and locked the OSD display. Now all the appears is a smaller box showing a lock which goes out in five seconds. It is still annoying, but less intrusive then before. Hopefully, some one will determine a permanent fix for this problem.
