Hello Fixya Guru's, When the monitor and computer are booting up, the windows pic comes up then the screen automatically blacks out; but, power light flashes green. Weird thing though if the computers screen saver is on before plugging in monitor the screen stays on til the mouse is moved. I've checked the monitor motherboard all looks good, if it is a cold solder what area should I resolder or is it possible the flyback is dying. Thanks Dave.

Re: Dell m992 screen problems
If you notice, when you see the windows start screen, its usually "big and dopey". Thats because the video drivers aren't being used yet. If it is blanking out right after you see that screen (with the scrolling bar), my guess is it's a corrupt / bad video driver.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

Usually this problem happens when the video card is sending a signal to the monitor that the monitor does not recognize. (Kind of like me telling you how to fix this problem in a language I dreamed up myself.) The monitor will work on a different computer, because that computer has a video card "talking" to the monitor in a language it understands. So the solution is a different monitor that has a resolution setting your computer can talk to. Possibly you can borrow one, change the resolution of the card, and put your own back in. You can plug in and unplug monitors while the computer is on with no problem, to test.
The labor rate in the midwest where I live is $50 just to look at it. Unless you have electronic experience and test equiptment, I do not believe you wil be ableo to service it yourself.Usually cheeper just to buy another replacement one.
If it's getting no signal, make sure the monitor is set for the correct input. This would be either analog (if your cord has blue ends) or digital (if the connectors are white). Depending on wt yhat your monitor is, a button on the monitor will help you set that. If it's set for the correct input signal, then switch out a different cable to see if perchance you have a bad cable out of the box. If there is another PC or laptop setting around, plug your monitor into that to make sure it's good and maybe even plug THAT monitor into yours to make sure there is nothing wrong with your video card. Let me know what transpires. If this takes care of things, please help me out by rating it accordingly.
does the screen show no signal, it could be from thedigital button setting on the monitor try to adjust the setting,
2.check the video card ,you can test it on another system,test the monitor on another systems thats working fine if it continues may be its frm the systems or the monitor tube is bad if your using the correct resolution
Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages. Good Luck!
The link below is a Digitally signed M992 monitor driver.
Also try upgrading to the latest ATI software and drivers. You can also try and change the frequency refresh rate to 75mhz. It in the Control Panel under 'Display' and tab 'Monitor'.
It shows a list for frequencies you can try.
