I turn on the monitor and the acer logo comes up and a moment later the bottom green power light goes off and the monitor resets itself and starts up to the logo again and i can not turn it off by hitting the power button i have to unplug it to get it to turn off. If i plug it into a machine it will display what it should and then resets again and again.
Hey Vine or Jinksko: I'm having the same problem. I got the cover off and the circuit board snapped out, but I don't see how to remove the ribbon cable from the board without breaking it. It's a white plastic connector - what do you do to disconnect it? Thanks!
I also had this problem, after googling for Aceral1912 troubleshooting,
found this site and followed the advice above about removing the button
circuit board, low and behold I found a spider had taken residence
inside the monitor, and the remains of the flies he had been feasting
on were shorting out the circuit board!
the problem is always corrosion on the circuit board that has the buttons disassemble the flat panel remove 3 screws that hold button board on disconnect the tiny cable from the button board use a tooth pick and clean inbetween the solder connections where the ribbin cable plugs into button board

Sounds like the monitor is dying, if it starts to die more and more often you will likely have to replace your monitor before it goes completely out. There are not many ways for a user to repair a monitor, unless the problem is with the computer, which you could test by connecting a different monitor to the computer for a while (if available). Hope this helps!
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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. http://en.wikipedia.org/wiki/Capacitor_plague http://www.badcaps.net
Most likely caused by defective capacitors in the power supply. This is quite a common problem. If you have some electronics skills, you may be able to change them yourself - look for bloated, otherwise deformed or leaking capacitors, typically in the 470u - 1000u / 25V range. Replace them with 105°C rated low ESR types of the same value and voltage rating. If you don't know what I am talking about, bring it in for repair (if it's still worth it...).
With the screen connected to the pc (which is running and putting out a signal) hold a bright light to the front of the lcd - a led flashlight works well. Do you see an image? If so then circuitry driving the inverter backlights may be at fault. I had this happen with a Dell Flat Screen, and found one of a pair of transistors which drives the backlight had developed a short.
An unusual problem for a flat screen monitor.
I suggest you connect the monitor to another PC to see if the problem persists since it could also be caused by the video card (or circuit, if on board).
Check your cables making sure they are solidly connected and wiggle them to see if you can cause the problem to come or go away; this would crudely check the shielding of them.
This kind of aberration could easily happen with a conventional CRT monitor if power supply filtering was failing but as mentioned, uncommon in a monitor that is essentially digital.
Not all monitors can display the same resolutions. You may have has the Dell monitor set at something the Acer can not handle. Try rebooting and if you can see the Dell startup screen press F8 as soon as it disappears. This will give you the Windows Startup Options menu, which is text and should display on any monitor. Then select VGA MODE, which is the lowest common denominator for graphics. You should be able to see the Windows display at a much lower resolution (ie, larger fonts and icons) than usual until you can reset your graphics properties to work with the new monitor.
i have experienced the same problem (power cycles on and off and on and off... nothing but Acer logo and black screen) on 2 Acer model 1706 A version 1706 Ab monitors both built in July 2006. Before the customer reported the 2nd monitor with the same problem, i sent the 1st one into Acer for warranty service (after testing in on 4 machines w/4 different video cards). They shipped it back with a paper saying the monitor was repaired. I returned the monitor to the customer and it exhibited the same symptoms (aka, not repaired). Could there have been a bad batch in July 2006? When I plug a new Acer AL1716 monitor into the same computers, I have no problems at all.
