I have answered this in other threads but to reiterate.... The Gray rectangle "No Signal" I use a Power Strip and Turn off as soon as it cycles back to Normal screen. It is so much easier then to unplug and Plug back in when it does happen. As for the Newer Problem(s) and I too have had mine for only couple of years... Copied from Previous post This is not a Fix to the Problem, If you read some of the other
"fixes" that relate to this you will see that it is a more serious
problem and one that Acer should Do the Honorable Thing and have a
I actually went in side on three of the Same Monitors and one that was
a 21 inch and found the problem is "HEAT"
You can see where a Board actually shows Browning on the Circuitry I am
Going to try to order a new board P/N:AS08B360411.
I will update as soon as work is completed.

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 first thing to check is , the Power, are ya sure it's plugged in OK, are ya sure that socket is working, try something else in that outlet to prove, check the power cord is pushed right in, Check ya on the right Video connector on the PC, make sure all conns are correct. Try the monitor on another base unit, try your base unit on another monitor. If all these are OK then ya Monitor has turned it's toes up sorry.
This Problem is Acer(s) Monitors. Though it is a nuisance one fix That has work for many is the Unplugging after it goes back to Good (viewable) screen. I have hooked mine up to an inexpensive Power strip to make it easier for me and just turn off at time indicated above and Viola Simple is as Simple does :)
The problem may not be the monitor. Acer AL1714 is known for its weak power supply unit. Unplug power supply from monitor. If the green light on monitor comes on but goes out quickly, the power supply is the culprit!
