Re: Acer 22 inch monitor shuts off with indicator still...
The computer may be programmed to do a monitor shut off after lets say 20 minutes. This is a power saving feature of the operating system. Open Power Options under Control Panel.. select the drop down combo box that says "Turn off monitor" : set it to NEVER.

if no any power led indicator at the front panel after of shut down, the cause could be power supply failure. you will need to remove the back cover to gain access of the internal part of the monitor. look for a blown fuse or burnt parts at the power supply board. if you have an idea about electronic parts just replaced defective parts with the same rating and value. hope this can help good luck just let me know if you need further assistance.
One missing color could just as well be caused by the graphics card (or chip) or, if using a multi-pin interface connector, it could simply be a pin that isn't contacting anymore.
The problem is, that red drive is missing.
Remove the end(s) of the video connection cable and reinsert several times to 'wipe' the contacts.
If the problem is constant and you have the opportunity, swap your Acer with another monitor or try yours with a different computer.
You need to roughly locate which electronics is at fault and that is the easiest way.
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
Post back what you see insdie so we can guide you furhter.
Look at the capacitors in the power supply. Replace them if they look bulged on wither side or leaking. Most likely it is the inverter (the flat object with copper coils about 2 inches long, 1 inch wide). Check the resistance with a multimeter to be sure its around 1000k on both pair ends. They supply the CCFL tubes with voltage. If one onthem is bad they are designed to shut off within 1-2 seconds. Note the inverter numbers and order the part from www.lcdparts.com. You won't get them anywhere as the parent company MoniServe makes the power supply board for Acer.
Yes, you do. You need an stereo audio cable. It will have a connector like found on portable headphones on each end.There should be a recepticle for it on your monitor, usually marked light green. This cable would then connect to your computer's audio output. Although, I don't think your monitor has speakers.
