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

    You can't open these monitors and perform DIY fixes. You can try connecting another monitor just to rule out the source of the problem being the computer. However, unless there is a power supply issue, I doubt you are going to resolve this. You can call Dell technicians and see what they say. I simply do not believe any of the other suggestions will be of much use in this instance.

Knowledge Base

The above link is to the Dell Knowledge Base and specifically to monitor problems. There are links on the page to "blank screen" or "no video." But that may not be descriptive of your problem. It has not been indicated whether any power led on the monitor is lit. What happens if you "turn off" the monitor and turn it back on? It is possible you simply have a loose cable or the power cord might be bad.

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 customer_advocate@dell.com, 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.

We have to push the on button on our TV from 20-100 times to get it to turn on. Have changed batteries and restarted to no avail.


"He said our TV has a problem". Brilliant! To be more specific, he could have suggested switch failure or a failing power supply.

Restart your computer,
and keep hitting the F8 key until a "start-up" menu
(white text over a black background) is displayed.
Choose "Safe Mode" and let Windows start.
Reset the screen-resolution to 800-by-600, and 60 Hertz refresh-rate.
Restart your computer, normally,
and then "tweak" the screen-resolution and refresh-rates that are "optimal" for your monitor.

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.

Xerox xa7 19" lcd monitor


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.

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.
