Question about Dell Computers & Internet

When I power up my monitor the display briefly flashes on - to the login screen - and then the display goes blank. If I use the power switch to turn the screen on and off the same thing happens - brief display and then nothing. Can anyone suggest a solution?

Open the monitor, look for blown capacitors and replace them. If problem persist, test the light bulbs and the inverter. If the inverter includes ceramic capacitor, replace it. If some of the bulbs does not do the flash - replace it. Check the transistors of the inverter. Replace if faulty.

ViewSonic VA720 Screen displays briefly then goes blank.


it looks like the Inverter's gone in your screen, it works like a starter in a florescent tube, it 'kick starts' your screen to come on. Turning it on/off many times eventually 'kick starts' your screen and makes it come on eventually.

Monitor displays breifly then goes to blank screen


If tried the monitor on two other computers with the same result -- definitly your monitor is faulty. Take it to the repair shop. To make double sure, run your computer with another monitor. If everything is fine now; you can blame the monitor.

The power -inverter board probably needs an overhaul.
I redo many of these.
If the screen was pinkish or flickering before it finally got to this point, it is possible that a bulb has gone bad.

I am not familiar with your particular model, but I do know what the problem is.
The inverter that runs the lights behind the screen is faulty and needs to be repaired. The lights shine from the top and bottom and reflect outwards through the panel so you can see what is on the screen. If you start the computer up, then shine a bright light into the panel you will see an image on the screen, but very feintly.
This can be cheap, it can also be expensive depending on where you go to get it repaired. Call aorund to a few TV shops in your area to get a rough idea on prices.

Hope that helps =)

Hi this is the way how to examine what's wrong with your LCD monitors. Power on both CPU and monitor. After going blank, you check that you can see the image on the screen by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken and it is easily replaced. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.
