The problem is not with your monitor the problem with your cpu which is not providing the signal that's why it goes off

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, 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 problem with this monitor is a leaking capacitor on the power supply board. It is the middle one at the top in a row of three. The value is 10V 1000uf. Common problem for these.
Remove 4 screws from back of display. The case can be popped apart with a small flat putty knife at different points along the two seams. Three latches on each side and two at top and bottom. Push and twist at the latch points. There is a metal cover over the two boards. Power supply board to left. Screws and plugs can be romved. Unsolder Capacitor and replace. Radio Shack probably has them. Maybe a couple bucks. Be sure the power has been off for a while. These also have problems with the button board and corrosion at ribbon cable.

I have the same problem on my Acer AL1711. The monitor was out of warranty so I opened it up and found one of the 1000 mf capacitor almost ready to pop. A 50 cents replacement from allelectronics.com fixed the problem.
Not recommended for anyone without experience soldering electronic components to PCB's.

Here is a link to get the manual:
http://www.acerpanam.com/synapse/data/7117/documents/X193W%20(Qisda)%20user's%20manual.pdf
Starting on page 15 are the directions for the monitor controls. Page 17 indicates a "RESET" feture to Clear the Old-Statuses of "Auto-Configuration". There are quite a number of setting for this monitor.
