Check the caps in the power supply first.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed ACER monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

The monitor powers up then shuts off then a second later it starts up again and keeps repeating


More likely to have dying power supply due to bad caps just like the rest of failed ACER monitors as shown in my albums here:

Failed TV, Monitors, capacitors, and lamps pictures: http://s807.photobucket.com/home/budm/allalbums


Please read my guide and read about bad caps.

Processing auto configuration


Check your settings in "Power Options Properties".
Control panel/ power options/ advanced/ under power buttons make sure you have "shut down" when you press the power button on your computer.
I hope I am understanding your problem correctly. If not pls. explain what you mean by and when processing auto config. keeps flashing. Is there a black screen or a windows interface?

Acer 22 inch monitor shuts off with indicator still green


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.
