Question about Dell M570 15" CRT Monitor
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
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.

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.

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 [email protected], place attention Richard in the subject line. We can assist you in determining what the issue is and help apply a solution. Regards, Richard

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.

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.
