The power LED light has become a diagnostic light. It's telling you that you have a bad Power Supply.
Weak voltage power rail.
Replace it.

If I knew the computer manufacturer name, and Model Number I probably tell you, and show you. (Some budget computer manufacturers have a poor support website, is why I stated Probably)

One bad/faulty lead can cause a computer with lots of problems
replace all the leads that attach to your hard drive including electrical extensions + IDE,SATA and the ones that attach from your motherboard to hard drive
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

Go to Control Panel, (top right View Small Icons). Then look for Power Options. On this page, you'll have the option to leave the monitor on. You should also check "Advanced Power Options". Don't be afraid of the word, "Advanced." It only means "customizeable"

If your mouse isn't waking your monitor, try the keyboard's space bar. I found it works better than the mouse at waking a sleeping computer

LCD monitor goes blank


It appears that the display resolution set in your display properties is out of the range that the LCD can display.

Try this.

Boot to the ENABLE VGA MODE by pressing F8 to get the Windows Boot Menu. If you can get to the desktop, then go to display properties, and see if you can change the resolution to higher settings and maintain video. (If the video blanks out, then it should revert to the previous setting in 15 seconds)

Green light blinking screen blank


Hi Suzee,

Is the green flashing on the tower or the monitor?

If it is flashing on the monitor, then it might be tht the monitor is not gettign signal from the tower.
To check, disconnect the monitor from the tower and check the monitor. If you get a msg on the screen like no input signal or check video cable, then 99% monitor is fine.

Check for the power supply light at the back of the tower.

Disconnect everything from the computer and then press and hold the power button on the comp for about 30 seconds.

Then connect the cables and check if it is working.

ViewSonic Monitor has trouble to wake up after been shut down?


Ok sounds to me like a power supply problem.. this a a fairly common symptom. I suggest that as a temporary fix you set the monitor to NOT turn the power off to the monitor in sleep mode if possible, in your power settings for the monitor.

Monitor flashes image for split second then goes blank but green LED flashes as well


while the monitor is still powered on, but with the LED flashing, unplug the monitor from the PC. press the power button, and the monitor should go off, now plug the pc back into the monitor. Turn the monitor back on and it should work.

Occasionally this will not work for me, but if I repeat it it normally works

Hope this helps - my problem is intermitant so it may be different to what u guys have

Blank Screen..Will not power off


Have you checked your video source to ensure that this isn't a problem with your PC or whatever you're displaying on it? Try using a different display and see what happens. Try putting this LCD on a different PC and see what happens. If indeed it is this screen then it could be something as simple as a loose cable. Start simple and work from there.

Blank Screen..Will not power off


The flash light test only works with lcd monitor as they have back lights. Double check the connections again, also, if you can borrow a monitor try it on your pc, it may be your graphics driver needs to be uninstalled and re-installed, but you will need a monitor to see.
