Question about Acer AL1914B (Black) 19 in. Flat Panel LCD Monitor
Might be a loose connection to your screen and motherboard.
I have the somewhat same issue with my Dell Inspiron 15, It's a touch-screen laptop and whenever you jerk the screen it'll either Freeze in like colored bars, or it will change colors. Both of which are annoying.
If anything, it may be a loose connection.

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. Its really great to see that this is a known issue. I tried the solution of viziks, allthough my monitor still has the name ''plug and play monitor'' . I wanted to try to install new drivers, where can i find those?

SOURCE: RE:monitor goes black
Monitor going black after a few seconds can be causd by a faulty power supply or inverter. Some monitors have both as one unit.
Sometimes it is basic failed capacitors, After that then I would look at transistors.
The average monitor from 17 to 20 and sometimes the 22s have usually 4 bulbs in them. One bad bulb will also cause the inverter to not fire up.
Bad bulbs usually show pinkish tint, or flickering or are dark at center top or bottom of the display.

You'll need to have your power board -inverter redone.
The capacitors are starting to fail and that eventually will stop it all together.
I repair many monitors through ebay with these types of problems.
If you take it apart and send me a picture, I can usually see the problem areas.
