When I start up, the monitor flashes on, and sometimes for a couple of seconds displays the screen. Then it goes black. If I cycle the power it flashes the screen on for a second then black again. For the second you can see the screen it looks fine. Your thoughts

Hello,

It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is usually caused by parts called capacitors overheating in the confined space of the monitor. If you are good at electronics repair/soldering you can usually fix the 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 pictures 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 david champ, sounds like you have a dead video device on whatever you are using it on. Try taking off the video lead from your computer, laptop etc and it should show a message saying not connected. Be sure to leave the power cord in the monitor.
