Firstly - Is the cabling, mains and data cable, securely attached at both ends and the power turned on at the mains?
Secondly - If so when you press the monitor power button, does a light come on? (often orange coloured) If yes does this change colour when the computer starts its boot sequence? (often to green or blue)?
If no light can be obtained it is likely that the monitor is faulty.
If a light comes up on power up, but doesn't change colour during the computer boot sequence then it is more likely to be the graphics card that is faulty, or sometimes the computer PSU.
The easiest way to find out whether the computer or monitor is at fault is to replace the existing monitor with a monitor that is known to be in full working order, for example from another computer. (Or connecting your monitor to a computer that is known to be working)
Having isolated the faulty component it can be replaced and you should be up and running again.
Hope this is helpful, if so would you please register that with Fixya
A quick check would be the VGA cable connection to the back of the PC and monitor. Make sure they are snug and completely connected.
Some monitors have the VGA cable attached as a separate item and not built into the monitor. If the 15pin plug becomes loose it will show the problems you're describing.
If that doesn't fix it, Next plug the monitor into a known good PC. If the problem still exists, you have a bad monitor...If the monitor works fine on the known good PC, the Video Card/Onboard video interface is bad and will need to be replaced.
One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up
Test all leads that attach to your hard drive including electrical extensions,IDE,SATA
the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty ?
hope this helps
this is a problem sometimes with hdmi. it also happens with dvd players. try to do a cold reboot of your laptop and see if that helps. also before turning of your laptop do the same with your monitor. turn it off, wait a few seconds, then turn it on. after that turn your laptop on.
Hi there if your monitor came with a cd rom use it if not you need to be sure that the monuitor is compatable with the pc also check the pins at the end of the monitor cable to be sure that they are not bent. also you can make sure that the monitor is working by trying to attach it to a nother computer and see what happens please keep me posted on this there is still a few things we can try to do ok best regards mike
One reason that this is happening could be that it is on Power saving mode. This happens when the LCD monitor detecs an incorrect timing then thats the time that the LCD goes blank and the power botton starts to blink.
what you need to do is to turn the computer off. Unplug cables attach to the LCD make sure it is also off, once done press the power botton for a couple of 30secs to a minute and then release. After doing so re-connect all the cables and make sure that both ends is tight and secure once everything is ok turn the computer on same with the monitor to check if it solves the problem.
I just changed my video card and after turning up my screen refresh rate (Hz) my monitor started doing the same thing. Monitor worked great for a long time but now its done! The only thing I can think of is that it has to have 60Hz, turn it up for gaming and its too sensitive to frequency. By the way, mine will turn on after a few power cycles.
Simply try replacing ALL the large Value Electrolytic Capacitors on that board, 1000uF, 470uF, 330uF, 220uF, they are "the big fat round blue things" marked with say 1000uF 16Volt or the like, get the EXACT same ones and replace them... this may indeed fix ya uint. Good luck.
