Question about Computer Monitors

Monitor goes black and won't come back

I have an acer monitor @ work. At least once a day the monitor itself will go black, but the power light on the monitor stays on (blue). I turn off the monitor, wait, and turn it back on. I get the acer logo and then it goes back to black. It doesn't respond to the computer (which still has power) and the monitor won't work again until I manually reboot my computer. It does not respond to the mouse or keyboard.

Will not stay on


Check the power cord where it goes into the monitor and make sure it is tight. When it turns off, if the power light is still on check that you are not getting message "No Imput"; it may be the serial connection on the back of the monitor or the back of your pc. Usually if this is the case the power light will be yellow, not green or will blink. Acer and Planar brand monitors are known for issues ranging from this problem to going completely black even when power light is green. If its under warranty, return it if trouble shooting doesn't work.

Dell E178FPf LCD monitor goes to standby and won`t come on again


Check your Power options in Windows.

right click on the desktop. select properties, Gop to the screen saver tab, click on the power button at the bottom right and check to see if its set to turn off or standby the monitor, turn this off.

Keep the screen saver on and set it for like ten minutes.

Also, on the monitor itself, it may have a sleep or power save option set as the default. check all the monitor settings on the actual moniotr itself.

Monitor goes black


Sorry to have to tell you this, but this is common in LCD monitors. The reason that it is going black when it boots is for one of two reasons. You either have a bad power supply that powers your LCD or your LCD's backlight is blown. These can be repaired or you can purchase a new one. But if it goes black 9 times out of 10 is because the backlight is bad. These can be repaired!
