Not sure I can tell you the exact nature of the problem with the info you have given. However, here are some trouble shooting tips. These are the things I would do to figure out what is causing the problem: 1. Hook up a monitor that works so that you can make some configuration changes to the graphics card. 2. Find out the native resolution of the LCD monitor that has the problem. Many 17 inch and 19 inch LCD's are 1280 X 1024 with a refresh rate of 60 Hertz. It is quite possible that your previous monitor settings are not compatable with your new LCD monitor. This is an easy fix. So go into your graphics control pannel and start by making sure that your refresh rate is set to 60 and the resolution to 1280 x 1024 or perhaps even lower like 800 x 600 but 1280 x 1024 is fairly standard with many LCD's. 3. With these new settings hook your LCD monitor up again and see if that works. 4. Still not working? ... Then there may be a problem with one of the hardware components in the monitor. When the monitor flashes are you for an instance seeing an actual picture? If so then the problem may be with your lamp controler. It's what controls the brightness etc. of your monitor. What you can try to do is lower the brightness. This sometimes restores the monitor to being useful. ie. you can use the monitor but only at a lower brightness. Setting the monitor to a lower brightenss may be a bit of problem if you can't see the brightness control which is often displayed on the screen itself through the menu function. If you are briefly seeing a picture as it goes through this 3-5 second cycle then hit the hardware menu button on your monitor. You should then see some sort of menu that you can control with the other buttons on your monitor. Find the brightness selection and lower it. You can lower it all the way to 0 and still have plenty of brightness to see a picture. NOte: you may have to make the change in brightness within one cycle of it going off and and on because each time it cycles it's quite possilbe that it resets itself. So in this case you would have to be really quick with the menu buttons on the monitor. It might take a couple of tries (or more) to get the squences of buttons you need to hit to get the brightness down. I had this problem once with a monitor and I was able to get the brightness down but only after many tries. I had to be supper fast with my menu selections. After that was done it worked flawlessly again. 5. Still not working? ... you are right you probably should have bought a new one LOL ... or next time when buying a used one make sure that you see it functioning correctly on a computer before buying it etc... Best of luck. Sincerely, Dean Dean Kenneth Robinson techinfo@ContinuousMix.com

ok every one there is a fix the are 4 transistor 2sc5707 and 2 transistorfu9024n and i cap 16v1000uf
if you replace these your problem will be fix for a while but to it better then dell replace the 2sc57o07 with radio shack tip3055 they are 15 amp trans instead of the low 8 amp dell uses they fail because the amps at the test for the transistor is more than 8amps all the correct parts are sold in a kit on ebay look up the 2sc5707 but i recommend upgrading to the tip3055 transistors they are a bigger transistor but you can lay them down and they work great. the capicator can be found at radio 35v1000uf is a good replacment make you monitor better because the new parts are stronger then the originals so no more failures after.

i just finished repairing a 20 inch acer monitor that had the same issue.... you have to take it apart and examine the power supply side of the monitor. there are capacitors that go bad on that board. you can tell be feeling the tops of them... the feel rounded. replace the capacitors and put it back together and it will work fine

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.
