Monitor screen picture won't stay on for longer than a second

Ok, same issue here as well. Monitor would come on for 1/2 second and then the backlighting will go off. It's next to impossible to tell, but if you shine a bright flashlight at the screen, you can make out the video signal/desktop.

I have now replaced all the Capacitors except the very large one (didn't come with the kit that was available.) None of my caps looked bad (bulging) including the large one. Unfortunately, I still habe the same issue

So my question is....large capacitor replacement or something else?

try running it in safe mode tap f5 when you see the dell screen. if it boots to safe mode remove the driver for the display adapter in device manager. the dell computer doesn't know what kind of monitor it's plug into. install the soyo monitor driver

Look for bad caps (bulging tops), bad transistors, transformers as shown in my pictures.

It is a hardware problem.You can repaired it from service center.

Make sure that your computer isn't going into Standby or Hibernate mode. You can test this by briefly pressing the power button and wait to see if the screen comes back on.

Hello Chris,

You have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of he monitor. If you are good at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts, replace any that look like the pictues and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the strip on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. I hope this helps, if so please rate my solution.

Video (picture) must be constantly entering a monitor for a monitor to continue to display a picture after it self tests (goes on for a second or, two) Your monitor is fine; check it using another known good computer.

"Most" newer monitors will let you know if the are no longer receiving a signal. Sounds like the backlight is burnt out. Try getting a bright (LED works best) flashlight and shining it at the screen at all angles to see if you can see any of what you were doing. If the backlight is on the fritz, either return it on warranty or buy a new one.

While it is sounding like a hardware problem. I'll throw in my 2 cents. Have you check the cables from the power to the source and from the monitor to the computer. Just make sure those aren't loose. One other thing...you mentioned you turn off the computer "afterwards" then it fixes itself. Is the fix for longer than it turns on at first? or does it stay on longer then goes out? Let me know what happens. Good Luck, Tim

Check the cable connections on the back of the monitor and the PC it sounds like the connection isn't made properly make sure they are tight.
