Monitor does not come on

My monitor displayed a very sharp, brilliant white light from its center and when I restarted it, it would not come on anymore. The other one just begins to flicker after being on for a while. I would have to restart it for it become stable again. After a while the flickering resumes

SOURCE: flashing on and off

I would suggest trying another monitor to rule out your PC or monitor card. I would also check the video settings on the PC. Then assuming your cable/connector and video card are okay, it sounds like a lamp or lamp driver (a.k.a. ballast or inverter) issue. In other words, an internal issue that probably needs component-level troubleshooting.

SOURCE: Monitor (Dell 1701FP) flickers, flashes and goes black

Hello, My name is Richard; I am part of Dells Online Community Outreach group. Solution 1 is good as the inverter may be going out. The inverter lights up the screen for the picture to be displayed, other wise you would only be able to see very dark shadows. In the end it would be a good idea to call our technical support at 1-800-822-8965 and find out if the monitor is still under warrantee. Or you can email me at, place attention Richard in the subject line. We can assist you in determining what the issue is and help apply a solution. Regards, Richard

SOURCE: dell 17" flat screen monitor

This is the way how to examine where the problem is. You have to check that you can see the image on 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 (Power on both cpu and monitor), there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken. It can be easily replaced. If you cannot see any icon on the screen. I would say that there are 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 dark 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.

SOURCE: My Dell 1905FP 19 monitor went black & green power light flickers

It sound like a short circuit. I had this problem with 1907FP model. It had an USB port on the monitor which got damaged and it was shortening to the groung. In your case it might be a bad internal power supply board.

If the problem is with laptop monitor, try restarting the computer. If problem remains, try connecting your laptop to external monitor to see if problem is with laptop monitor or with display adapter.

If picture also like this with external monitor and with laptops own monitor after reboot, possible HW issue can be expected.

It is the picture picture board on your monitor that is malfunctioning, since the power led or button is on, but the display screen goes blank, it means the picture board of your monitor has developed fault.

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

Take care.

Screen returned from supplier background bright pink, how do I change to white background.

To check if the video card or the Sharp LCD monitor is faulty, connect a different monitor to the computer. If this monitor displays a normal image then the video card is OK and the Sharp LCD monitor's back-light is faulty. Send it back to the supplier to have it fixed (they should not have reurned it to you in this condition).
If the other monitor also displays a bright pink background then the video card is faulty and needs to be replaced.

That means that you have a defective inverter board.

The inverter is a small power board that power up the LCD backlight lamp, determining light intensity, when it is like that, the inverter is defective and must be replaced.

Lacie 19" Electron Blue - Black screen with a brilliant white line across

I have 2 of these monitors and have this problem. I was so frustrated turning the monitor off and on until the white line disappeared that one day, I punched the screen. And it worked! So now whenever this happens (about once every other day) I use my palm and smack the lower left corner of the monitor until the white line disappears. I like the color on these screens so I don't want to replace them until I have to. I will NOT buy another Lacie though.

White colour is displaying as yellow

Your monitor is missing blue drive. Most likely a component failure on the CRT board. Bad color ICs, bad solder connections or defective capacitors can cause the problem.
