Question about Dell M991 19" CRT Monitor

1 Answer

Dell Monitor My Dell Monitor seems to have quite working. There is a light on the front of the monitor that is usually green when all is working correctly but now it stays orange the entire time. I am wondering if it is time to buy a new monitor or if this is something I can fix. The monitor is about 4 years old and is on pretty much all the time

Either the cable is not connected to the proper port or the display-source is not configured properly.Here's what you can try.
  • Ensure that you have connected the VGA/DVI cable in the correct port. If you have an extended graphics card in your computer, use a DVI cable(Digital input) else the VGA would be the only option available.
  • If the cable seems to be plugged at the right place, press the first button from the left on the front panel of your monitor (Button 1 shown in the front view:, once. This toggles the digital mode to analog mode of your monitor, and vice versa.
  • If the first two steps do not work, its not an issue with the monitor. It could be a failing cable or a defective video card, or the system itself is not completing the POST.

Monitor problems

It seems that you are trying to use a graphic mode that your monitor doesn't support.

Restart windows in safe mode, go to Control Panel. Click on Display. Select settings and change to a resolution that is supported by your monitor (I don't know your model, but 1024x768 is a safe bet).

Restart the computer.

It should be working by now.

Good luck!

I am sorry about this but the correct repair for this issue is replacement of 4 transistors on the main power board inside the monitor I just completed a repair on a dell 17 inch monitor it now works flawlessly. the process can be found on the internet and it is very delicate work. if you can all their service center you used then by all means call them,
you have a nice day now.

The orange light means that the moitor is not seeing any signal. Make sure that the cable is in the correct position on the PC. If that is correct, try it on another PC to determine whether or not the monitor was damaged internally during moving or the PC is not sending out a video signal.

If all your lights are on on the front on the 2000FP then the logic board is bad and the eeprom at49bv8192at will need to be replaced and reprogrammed. Check out for Instruction videos on the 2000fp as well as parts
