When I woke up this morning, my monitor was black. I have an EN-7220. First, I tried jiggling the monitor cable (hooked up to my video card), to see if there was no signal coming from my PC. Every once in a while, the screen would come back on, but only for a few seconds, before shutting back off. I then began to realize that the image would appear, if I turned the monitor off and turned it back on. The image would appear then, but only for a moment. This is obviously on the side of the monitor, but I can't tell what the problem is, or what happened. Your help would be greatly appreciated.. It's not my monitor, it's a friend's, and I need to return it soon.

Make sure she installed the envision driver. I jus saw it's a discontinued product. Also this product has a maximum resolution of 1280 x 1024.

If installed check her resolution. Right mouse click on desktop>properties>screen. Try alternate resolutions and see what happens but don't set it higher then 1280 x 1024 if possible.

my suggestion is try to contact an expert technician of your monitor maybe it has loose contact inside.or before contacting anyone else try to boot your pc in safemood, if it runs smoothly then your monitor cannot support the screen resolution of your pc.

This is a problem with either the power supply or or logic circuit. It could also be caused by a failure in the back light circuits. One of these problems has caused the power supply to go into protection mode and will not turn on due to bad voltages sensed in the feedback circuits. Return to dealer for service. Hope this helps you .

SOURCE: the monitor turns on and connects to my computer then turn off but the power stays on. any ideas?

Make sure the external VGA port on your laptop is enabled. Not all laptops automatically detect a monitor connected and turn on the port. There will be a function key somewhere on the keyboard to control the port. Location varies by manufacturer and model. The usual sequence when you press the key is: laptop display on and external VGA off, laptop off and VGA on, both on.
