Dell flat screen monitor is repeating images

SOURCE: image go off

I have had the same problem. I've just managed to get the monitor working again by VERY QUICKLY navigating through the monitor setup menu to the 'factory reset' option and hitting reset before the screen had a chance to blink off.

The problem I had is that the monitor suddenly goes black, but will come on for five seconds if I switch it off and on with the power button.

In that five seconds, I had to...
>Hit the menu button
>then hit the '+; button once
>then hit the menu button again
>then hit the '-' button
>then hit the menu button one last time

The above brings up the menu, scrolls up off the top of the list to the last item on the list (Factory Reset), selects Factory Reset, selects 'All settings' and resets the monitor.

I don't know if this is a permanent fix, but it just worked for me and mine has been doing this intermittently for the last week.

Give it a try, it's frustrating and will take a few tries, but it can't hurt.

Check inverter board for bad 2sc5707 drivers...could be shorted.
Also check driver transformers for over heating symptoms...they could also be shorted.

go to safe mode and return the settings back to day when it was all working fine. Use system restore.

Hi this is the way how to examine what's wrong with your LCD monitors. Power on both CPU and monitor. After they shut down on their own, you check that you can see the image on the 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 or any image, there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken and it is easily replaced. If you cannot see anything on the screen, there'll be 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 burn 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.

If your Dell monitor still under into warranty, better to call Dell technical support and have them replace your monitor coz there is no way you can fix on it.

If the monitor is beyond with the warranty already, better to but a new one than taking it repair that will cost you much.

Thank you.
