This sounds typical of a failure in the back lighting system. You may be able to see a ghost image on the screen.

Typical repair cost is $80-$150 depending on what actually need to be repaired and labour rates. Check for warranty first, if its covered then get it fixed but you also want to check out replacement cost as the repair cost is close to what a new monitor will cost. So if you have to pay for this then consider getting a new monitor.

Try a known working monitor on your computer. If the video stays on then you know the original dell monitor is bad.

If you try the know working monitor and the video doesn't stay on then its a video card issue at that point.

That happen when the display detects a failure and goes off, likely a short circuit. It is a monitor issue. Looks like you are one of hundreds unfortunates clients that got a broken inverter driver. Here are instructions how to fix it:

I do not recommend you to follow the steps there provided if you don't have any experience about computer repair.

No image on laptop screen. off board video works briefly.


If it has XP on it, the fix is to invest in a new laptop I am afraid. It has passed it useful life and there is no support for XP. You could strip it down, but the Graphics card is part of the motherboard. If it was the exciter, the thing that powers the screen, you would get a perfect picture on a secondary monitor. It should display automatically using generic VGA drivers. Once you have the OS loaded on the monitor, you then customise to the monitor you have and then the settings. This leads me to to think it is the graphics on the motherboard. Try reinstalling Windows XP over itself. If that doesn't work, invest in a new one.

My emx-mcp61p-avl has power but no display no beep. video card is new and compatible with my motherboard. RAM is new also.


Just because the ram and video card is new does not mean they work. But since you say it has power, I'm assuming it boots up all the way except the screen is not displaying.

If this is a laptop try the steps below.

Shine a flashlight on the dark screen to see if you barely see 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 be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without 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 correct key for displaying on the monitor (F1 thru F12). The correct key will normally 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 light and nothing shows on the external monitor, then most likely your video card is bad.



If it is a desktop try the steps below.



Try connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor shows the display, then your original monitor is bad. If the Borrowed monitor does and same as your original monitor and does not show a display then your video card has an issue.

My computer is on and has a blank page and it will not let me get to startup


What do you mean blank page? And what is startup? Is startup the desktop with your icons? Tell exactly what happens and what you see when you power on the computer.

Maybe you are saying your system booted up all the way except your screen is blank. If so try the steps below.

Dell e173fpc Display Issue


Check if the cable connected to your monitor and video card is fix and secure.. Check also if the video card is properly seated in the motherboard.... Try to check using other computer if the video card is working..

If the test is all ok.. then the last option will be to check the backlight inverter of your monitor....To do this, you need to bring the monitor to a credible technician to have it replace..



much appreciated if you could rate this help..thanks..

All of a sudden I have problems with the LCD Display Panel of my samsung laptop. There are think dark lines that keeps scrolling in the panel. Any suggestions


Try connecting it to an external monitor... if the problem persists on the external monitor, then you have an issue with the video card or motherboard. Try drivers first, then replace parts.

If the problem does not occur on the external monitor, then you need a new LCD screen.

Good Luck.

Display went from extremely dark to complely black


Hello there.
I understand that your Notebook is not showing the display lights. To isolate the issue please do the following troubleshooting steps.

1) Check the display with external monitor. If the external monitor is showing the display then the problem is with the LCD screen. If the external monitor is not showing the display then the problem is with the display card.

2) If you have any torch light or a cell phone , try focusing the light on the LCD screen after the Notebook is powered on and check whether you are able to see the texts and images on the LCD. If you are able to see the images and texts then it is the problem of the LCD back-lights. The lights which glow at the back of the LCD panel are not working.

If your Notebook is under warranty HP will repair it free of cost.

Contact HP customer chat center for more information regarding the details of the repair and the procedure for sending the Notebook to HP in case of repair.

For contacting HP chat support click on this link or copy and paste it in address bar of a web browser.

No visual display


It sounds like your graphics card is shot. If your graphics card is a dedicated graphics card, you might be able to get it fixed/replaced; if it is embedded, then you are probably going to have to buy a whole new display screen.

Gateway 3522GZ display


Some searching on forums convinced me the inverter had failed. Picked one up for $65, removed the frame around the screen, removed the mounting screw for the inverter, and unplugged both ends of the old and plugged in the new. Put it back togeher and fired it up, bright again. Key here was that a remote monitor still worked which meant video card was OK. The lamp could have been bad, but apparently the life of lamps is pretty decent.

VGC-RB50 Display Problem


I hate to be the bearer of bad news, but I think that the MB or the processor just took a dive on you. Most likely the processor... as you are able to power up. If it were the memory or the video card, you would hear a series of beeps when trying to start the computer. And you already verified the monitor is fine.
