WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Test all power and data leads that attach to your hard drive IDE,SATA the leads from your (motherboard to your hard drive) make sure they have secure dust free connections and are not faulty if its a 40 pin flat ribbon type it will be the first to fail make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even something as small as a faulty electrical fan and its lead can cause you problems computers need all power and data to continue through every working device and to have an end so any faulty leads will end up with a computer error Check your RAM. The RAM is located in the middle of the motherboard. There are tabs that you can push to release the RAM. Remove it and put it back in place until the tabs pop out. Loose RAM can cause your computer not to start properly where you want to see a video signal.
Make sure your graphics card is securely seated with no dust built up or in the socket if you remove your graphics check the socket to make sure its dust free Restart your computer then reinstall it this should activate found new hardware wizard Check the vga lead for secure dust free connection or try another vga lead.
blinking blue lights means the monitor is stand by.for the black screen you should check your cabels from monitor to computer.they should be seated tight.if still no picture your videocard is proberly brooken. it should be point out at LCD-monitors are fragile.
Sounds like your monitor has croaked. Borrow a monitor from a neighbor, friend or family member just to see if it works. If it works, your monitor is bad. If the borrowed monitor has the same issues then your Video Card in the computer is bad and needs to be replaced.
is it an LCD monitor?
if so then it's more than likely the backlight tubes or the backlight tubes inverter supply has died is it fixable but i am not sure how much it will cost you at your local repairer and monitors are so cheap these days its probably not worth it!
hope this helps,ben
This is most likely the power inverter board in the monitor - this is common in many monitors. If it started taking longer and longer to display an image, and the power light is blinking on-and-off, that's the problem. You can confirm that it's the monitor and not your computer or the cable by plugging in another monitor if you have one to try.
If it's under warranty, send it back, if not, there are inverter boards for many common models of LCD monitors that are replaceable. The board can run anywhere from $50 on up. Depending on how old it is, you may find it better to just replace it with a gently used one from ebay.
usually that is an indication that the back lights on your monitor is not illuminating your screen.... here's a test start up your machine and look at the monitor real close.... or shine a flash light at it... you may see your desktop afintly... which means your monitor may need a new inverter board or possible to change some capacitors on it.
you can also try another monitor just to make sure it is ur monitor which is problematic
That is so crazy. You say you previously was able to see the POST screen and now you can't? You say you switched monitors and card outputs to no avail? Is the card an ATI with an aux Molex power connector? Is the puter actually going into standby or hibernation? Have a boot disk? or a PE? How about a Linux self-install distibution CD. Just kidding about that last one. Not really, you can see if the puter does respond.
Don't rule out a faulty power supply. Video card fail is usually one long, two short beeps at POST. or 8 short.
Prior to attaching the SynchMaster and if there is another monitor, pls try lowering the Screen Resolution of your Display Properties. It may also be necessary to lower down the Screen Refresh Rates. In some video card, you may have to activate Twin/Extended view or enable the use of a second monitor assuming that your regular monitor is connected to the standard 15pin VGA and that the Samsung would be the 2nd monitor using the DVI.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
