The amptron monitor will flick on for a split-second (long enough for me to momentarily see the desktop) with the center power (green light) lit...for a split-second. then its off for a few (3-5) seconds. Then it begins again. Split-second flash (power light and monitor) then nothing...wt hey?

Are you getting any video on the screen? I would make sure the power cord in the back of the monitor is securely seated. Make sure the video cable from the monitor to your desktop is screwed in tight as well.
Hope that helps

Since your green light comes on momentarily, you may have hope. Look in your manual or on Dell website to how to reset your BIOS chip to the default. You do this with the power off, unplugged. There is a 3 pin jumper which should now be in the normal mode. Moving the jumper to the clear mode for 30 sec. should bring the Bios to default. Should the monitor stay on, you will have to set the time and date and maybe a couple other tweeks. Good luck.

The power supply (AC adapter) is bad. It has enough power to light the red LED, but not enough to power the TV.http://shop.ebay.com/?_from=R40&_trksid=m38&_nkw=12+volt+5+amp+power+supply&_sacat=See-All-Categories

If you mean the on light goes dim, then I've had the same problem - unplug both computer and monitor - hold power button for monitor for 15-30 seconds...then power it back on and then power on the computer. Seems from other sites there is a power issue with the monitor - this worked for me.

The inverter is faulty.If your Monitor is powered by a mains'kettle' type lead,then it MAY be repairable,provided you can find someone to do it.If you have an external power supply,then the chances are you have a separate inverter,and it is doubtful whetther you can find the fault or a replacement circuit board....which is why we have become a throw away nation !!

did you changed frequency of that monitor? if it is out of factory setting that could be the problem, try to connect it again as secondary and set Hz to default, if that does n't work try same settings on both monitors? i have connected two monitors i had same problems , my secondary monitor was clone for tv if you are using secondary monitor for clone to ty (with s-video or whateever) if tv is old it must be 60HZ 800x600...

"Most" newer monitors will let you know if the are no longer receiving a signal. Sounds like the backlight is burnt out. Try getting a bright (LED works best) flashlight and shining it at the screen at all angles to see if you can see any of what you were doing. If the backlight is on the fritz, either return it on warranty or buy a new one.

You can email [email protected] and provide your telephone number... he will call you to assist.

Lower your resolution on your computer. Usually when that happens the resolution is set higher than what the monitor can support. Lower the resolution and try again.
