Monitor went black and now stays black after

I have had the same problem as others seem to have had with the dell flat panel. After leaving the screen on for some time, the monitor brightens for a moment, then goes black, while the green light stays on. When I reboot, it works again for some time, or if I remove the cable for a few minutes and plug it back in (with monitor turned off) it will come back on...only to repeat the black screen. I have changed the power features, screen resolution, downloaded updated drivers from dell, and viewed dells troubleshooting advice on the monitor cd that came with the computer. Nothing directly advises on this problem, but I have read here and in other online message boards the exact same problem. Anyone able to fix this?

my suggestion to you is that you try connecting to an external monitor and see whether it works or not then we can proceed basing on your feedback....please,let us know the outcome

Sounds like the monitor is cycling power.
Try plugging the monitor into a different power socket. Try not to use the same power bar as your computer

motherboard and graphics adapter may need replacement

check the cable who comes from the cpu

The amber light is the error light on a Dell. It can mean a few things. 1. RAM has went bad, not properly seated. 2. Video card has went bad or come unseated. 3. Power supply is not working properly; or 4. Motherboard has went bad. Hope this helps & please remember to rate my answer.

Hi! Trish,

It's seems your Acer monitor backlight inverter are burnt out. Need to replaced a new inverter. Since is a company monitor asked your boss to get you a new one.;) Hehehe...

contact the tech support 18006249896

I perhaps can. I would think inverter or ccfl's.

It sounds like there's a problem in the power supply or inverter section and it's just teetering on the edge of failure. The disruption of the signal is apparently just enough to kick it over the cliff until it's reset. Sooner or later, it'll need some help, like connections, capacitors, output transistors, capacitors, transformers. Those are the most common failures in these. I think you'll see it get worse
