The only solution I've been able to find for this is to turn off the computer for a minute or two and reboot, while rebooting, it is important to keep the mouse moving so the arrow on the screen moves. This should provide a temporary fix, I'm unsure about a permanent one.

Tyris Model: F179
Purchased an AsIs non-Working Tyris F179 from Goodwill for $15. Opened the case, found no swollen capacitors. Tested the capacitors on the power board and found C203 680uf 16v and C202 680uf 16v only partly working. Could not find a pair of 680uf caps and since they were in paralell on the same traces I removed both of them and substituted with a single 1500uf 16v capacitor. Next, the video board does have a Novatek chip much like the Novatek chip in the Samsung 710n but look closely at the 5 and 6 legs, they are not being used in the Tyris design so the 5/6 50ohm resistor fix is not needed here. Did find C107 , C16, C50 weak, all 47uf 16v, so i replaced them. Reassembled and now have a great picture again.
i'm not an expert at anything...x'cept maybe dumpster diving. God Bless

SOURCE: power supply on 17" acer monitor
franh, Typical of a lcd/fpd monitor! There is nothing you or hundreds of others can do to repair it all by yourself. I have repaired 3 monitors and helped tutor 2 others on fixya with their monitors. All had same exact symptom as your monitor. I need you to do a simple test for me. With failed Acer monitor near to your Fully Booted PC with a known good desktop being displayed on back-up monitor, quickly swap out the monitor cables from the back of the PC. Keep touching the CTRL key on you keyboarb every 30-50 seconds to keep the PC from sending out sleep mode command to monitor while doing the reconnect of acer to your PC monitor output port. Make sure the Acer also is connected to a live wall outlet/power strip. Turn on the Acer and note what happens. If screen shows a sharp clear image for a second, then goes black, do the following. Get a bright flashlight and shine it on the screen from a distance of 1 or 2 inches and tell me if you can see the desktop display. get back to me with your observations. I'm louie12fix on fixya or lmistyrel@ aol.com.

Bad transistors, caps, cold solder joints. Basic LCD monitor and TV troubleshooting guide: Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you.
If you are going to DIY and already try the monitor with another PC, 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 DELL monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.
