The screen goes blank after I turn on the monitor. When I turn it off and then on again, I can see for a few seconds and then the screen goes blank again.

Hope this helps.... Your monitor has an inverter issue. You know it's an inverter problem when:
1. Your monitor starts normally and displays the startup/desktop screen for a while.
2. Then it suddenly goes off, leaving a blank (black) screen or a very dim display.

To fix this black screen problem, change the inverter board (based on your monitor brand). Source(s): http://lcdmonitorrepair.annics.com

Hello,

If you turn the monitor off then about 1020 sec turn it back on and have a picture for five sec again it sound like the power supply in the monitor. but if that did not solve the problem, the picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault and will need to be replace.

I advice you replace the picture board on the screen of your monitor to solve the problem of the blank screen.

Take care.

It basically goes to Power Save Mode. Check for the same error in System Setup screen, if the Monitor goes off in System Setup then you better need a replacement. Else you would need to reseat the Video Card(If any) and the Memory Modules. Please keep posting for any further issues / improvements.

Run a monitor aelf test.... Remove the monitor cable from the back of the tower... and see if it run self test.... also a install the driver for the monitor

Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.

Hello Robert,

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 stripe 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.

Hi ,
The monitor flicker problem. The monitor when turn on will display image for couple of second then turn black. The monitor status led is still green. This will happen each time it is turn on. The symptom at appear to come from the inverter board.

Video cards that can handle two monitors at the same time have cables with two plugs on the monitor end.

If your video cable has two plugs on the monitor end, try the other plug.

There may be problem of heating the inside components. see him to expert.
