Could be with the monitor or video card/controller. first thing is to test another monitor if available and use a working video cable. if same thing happens, test if it is stable in safe mode. Restart the computer and press F8, then select Safe Mode. If display is stable in safe mode, it would be a video controller. Uninstall the existing driver, then download the latest one for your system through Dell support site.

Failing Inverter An inverter, typically found inside a laptop computer, consists of a small board, which has impregnated electronic circuits stamped on it. Inverters look like thin boards about the of two sticks of chewing gum. The inverter and its bulb control the intensity of the liquid crystal display, which lights the screen monitor. The computer can control the output voltage of the inverter and either lighten or darken the screen. A special type of inverter can adjust the brightness of the screen by using an internal sensor to judge the room brightness, and then adjust the screen accordingly. Failing inverters give off some specific warning signs, which can be recognized by observing different screen characteristics.

Short Intermittent Display Upon turning on the laptop, the screen flashes on in the normal mode for a short period and then blinks to black. A very faint image appears in a dark background, which will be very hard to see almost invisible. After shutting off the laptop and restarting, the same mode occurs, where the screen appears normal for a few seconds then fades to black. This condition points to a failed inverter. To confirm this, plug in an operational external monitor; if the external monitor functions, the inverter has failed. b> Total Blackout with Ghost image b> The laptop turns on, as indicated by the power supply button, but the screen comes up black. The screen comes up black after restart. You might be able to detect a very dim or ghost-like image on the monitor. When you plug in a known functioning external monitor, the external monitor operates normally. This mode of display indicates a failed inverter. b> Long Term Periodic Operation b> With this failure mode, the laptop screen illuminates normally upon start-up and remains that way after several minutes, hours or even days, until it goes very dark again. Brightness controls or restoration attempts do not work. Most often, the screen will function normally with a computer restart, but will eventually return to black. Faint ghost images might appear, as seen in the total blackout mode. b> Dark With Color Variation b> Upon computer start-up, the monitor shows black or dark gray, accompanied by very faint images. The screen might have an intermittent color change, or remain on with a non-standard color variation, like pink or red. b> Auto Control Switch b> If the screen appears black, with no faint or ghost images, look for the lid switch near the back hinge. The switch, when depressed with a closed lid, shuts off the computer and monitor functions. Sometimes the switch becomes stuck in the closed position, disallowing the computer and monitor to turn on when opened. Pushing the switch manually several times can often free it up. If the switch tab has broken or jammed inside the case, it needs replacing. b> Loose Connection In this mode, the display looks normal upon start-up, but tapping the side case of the computer turns the screen black. More tapping results in the screen functioning normally then cutting out again. This condition points to a loose wire connection from the inverter to the LCD backlight lamp, or the video cable. The connectors can be accessed by removing the monitor bezel screws and pulling the plastic retainer off. Both connectors can be cleaned and refitted.

Monitor goes blank less than a second after turning on.


Sounds like either there is a bad connection from the computer to the monitor, or the monitor has a faulty power regulator, causing the monitor to overheat prematurely, and shut off.

Screen comes on then goes dark turn it back off and same thing comes on and then goes dark you can barley make out imagies on screen


If you plan to DIY repair, then please read below and look at the pictures at the link I provide so you will know what to look for inside the monitor.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

DELL 2208WFP LCD-Comes on normally, but almost immediately goes dark You can see something on the screen if you look closely. Turn it off and back on you see it then dark. any help?


Hello,

I believe the power led button is still on while the screen goes dark, if yes, it means the picture board of your monitor is bad that is why it appears for a second and goes dark after that

Since the power led button is on, It means the picture board on your monitor is faulty that is why it appears for a second and goes dark.

The best thing for you to do now is to take the monitor to a local repairer or any service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself in other to complicate issues.

Take care.

Mag innovision LT716s monitor


When I turn on my computer the monitor takes a long time to warm up and colors change and vertical lines flash across the screen from right to left before the screen becomes normal again. Now the power light even goes out upon turning on my computer and I have to unplug the video cord and plug it back in to start the screen back up which even takes longer.
