The most common problem. It is related to old backlight lamps. The best solution is to replace them, but if you don't care a lot about total brightness, you may simply replace faulty lamp with 27pF 3kV capacitor, soldered across the high-voltage connector. That would be equivalent load for the inverter.
First of all, you need to find which lamp causes that problem. Disconnect flat cable from the display so all backlight will go through the screen. Now, using that 27pF capacitor replace lamps one by one and check when the light will stay for longer time. Keep that configuration as temporary solution, but make sure you will isolate your capacitor well, 'cause there's about 1000 volts applied to it.

I have a gateway dx4200-09 and when I boot up the screen goes black a few seconds after we turn it on and can't do much without visual have to constantly turn on and off monitor for brief glimpses


Either the Monitor or Video Card is going bad. Since it comes back on by turning the monitor off and on, I suspect it's the monitor.

If you have another monitor, plug it in and see if it works. If so, the problem was the monitor.

If you have another computer, plug the monitor into it and see if it works, if so, the problem was the video card.

Dell Dimension 3000 Video problem


There may be a problem with your windows installation. Search Google for Hirens boot CD, it is a free download and should contain a live XP installation. When you turn on the computer tap the appropriate button to reach the boot menu, then insert the CD and select your CD drive. Once booted it should display a live XP.
Alternatively you may have your monitor set to an incompatible resolution. If tapping F8 won't display the advanced boot menu then try finding an auto setup on your monitor or change the resolution using the monitors controls. If the advanced boot menu does display then select low resolution mode.
Hope this helps,

Hello,

I believe the power led button is still on while the screen goes black, if yes, it means the picture board of your monitor is bad that is why it appears for a second and goes black after that

Since the power led button is on, It means the picture board on your monitor is faulty that is why it appears for a second and goes black.

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

Take care.

Lg l1920 lcd monitor's screen flashes when turned on


Could be an inverter problem, if it powers on for a brief second and then flashes off then the inverter is at fault. Check for any Capacitors which have a yellowish substance at the top, they looks like round blue or black cans and if they look like they are buldging then they will need replacing.

hope this helps =]
