Suddenly my Acer X171 seemed to stop working. All we got after Windows login was - No Input Signal' message. When I connected it to an older CRT monitor it works. If I change the resolution on a given user - it seems to work on the ACER - but when I switch users - it goes 'dead'.

Along with using another monitor to change resolutions, try changing Refresh Rate (in advance button), then hooking the LCD back up. LCD's typically like 60Hz Refresh Rate best, but try several.

The power light is flashing green can indicate start/restart of the power supply due to shorts circuits or failing power supply due to bad caps, look for bad caps with bulging top first, see example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

No display. Acer logo flashes on and off

Now try taking that monitor to a different computer. Take it to a friends house or the office. Don't worry it won't harm there computer in any way. If it still doesn't work its the monitor.

Also, you may try lowering the resolution on the display settings. Do this by right clicking on a blank spot on the desktop and selecting display settings. Lower the resolution to 640 x 480 or 800 x 600. The reason for this is the current setting may be too high for the non-working monitor. Different monitors support different settings. They are not all equal, especially if one is older or newer.

No Signal

Not all monitors can display the same resolutions. You may have has the Dell monitor set at something the Acer can not handle. Try rebooting and if you can see the Dell startup screen press F8 as soon as it disappears. This will give you the Windows Startup Options menu, which is text and should display on any monitor. Then select VGA MODE, which is the lowest common denominator for graphics. You should be able to see the Windows display at a much lower resolution (ie, larger fonts and icons) than usual until you can reset your graphics properties to work with the new monitor.

Acer LCD Monitor - Stuck Displaying green

Cant say for sure. The display seems to be working, and the computer signal seems to be the problem. It could be a faulty cable. Check the pins on the cable monitor and see if they are bent, etc.
If the connectors are Ok, it could be the converter or the main board that has the fault. This could be caused by a power surge, or just a mechanical failure.
There is no easy diagnosis for this\ one, without actually checking the parts. I would recommend taking it to a repair place.

Acer LCD Monitor only displays "acer" logo

You are correct, it could be a power surge that has caused it.

Try this..
Unplug the monitor from the wall.
Remove all the video connections at the monitor end.
Wait 10 minutes then plug the monitor back into the wall (do not connect the video leads)

Turn it on and see if it goes past the ACER logo now. If so, replace the video cables and try the computer.
If not, then one of these will apply and a tech will be required..

The internal bios has been corrupted.
The power supply inside the monitor may have issues preventing the video board from starting correctly. This could be as simple as a few failing capacitors.

Number 2 is the most likely cause with an Acer monitor though. Any local tech will be able to correct it fairly cheaply, but phone around for quotes..they can vary a lot.
