Acer AL1912 Monitor Looping

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.

    I am having the same problem with mine.

    Acer AL1916 - same problem. It usually occurs in 'bursts', cycling on and off every few seconds, several to a dozen times, then it will be O.K. for days. I have been unable to associate it with temperature, time-on, display content, etc.

    Mine is an AL1912 but there are no 3 screws on the button area, only 4 on the back and I can't seem to get the cover off. I'm having the same issues. Help?

    I have exactly the same issue as the rest here. Problem is I have not figured out how to get the monitor open to I can clean the corroded area.

    Same problem, but I specifically associate it with turning the monitor on cold. For example, if I leave the monitor on all night with a signal source going (ie. leaving the computer on also), then there is no problem since the monitor was never turned off. When the monitor is left off, usually overnight, then turning it on in the morning will cause it to loop a few times, but it usually regains stability by the time the boot up process of the computer finishes, so it is more of an annoyance than real problem.



    Whatever the internal degeneration is, it seems to be affected by temperature. The cooler the monitor starts out, the longer the looping event will be. Of course leaving the monitor and computer on will "solve" the problem, but waste a lot of energy too unnecessarily. Given that it is temperature related, I suspect it might be from condesation on some critical contact, but as the monitor circuitry heats up, the condensation burns off allowing normal operation.



    The local temperature charts where I live are typified by a sudden cold snap when winter approaches, and subsequent "winter" temperatures for several months, so the problem was much more delineated for me. Prior to the cold snap, the monitor worked normally, after the cold snap the morning power-ups began looping.

    Same issue, stays on for 30 seconds when bootiong up, then starts intermittently off and on. Jsut a pain, I wish Acer did not make that kind of equipment, as it is expensive.



    Anyone figured out what is causing this, must be a circuit board failure or connection failure.

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!

Thanks fixya! saved me £££££££

disassemble the flat panel remove 3 screws that hold button board on
disconnect the tiny cable from the button board

Monitor comes displays Acer logo and goes black after 3 seconds, with indicator light still green.


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.

Acer AL2216W's green light goes off completely when the computer is turned on. When I turn on the computer and monitor, there is green light on on/off button while an irritating Acer logo is showing up....


You may have failure in the power supply due to bad caps, bad inverter circuits such as shorted transistors, transformers, bad lamps. You need to open it up and make some measurement, see example of failed ACER monitors: http://s807.photobucket.com/home/budm/allalbums

Acer monitor AL1706 Power On problem


You are more likely to have bad capacitors problem in the power supply, inverter circuits. I would look for bad caps first. Look at some of the sample here: http://s807.photobucket.com/home/budm/allalbums

Acer AL1914 black screen, green light


it sounds like a deleted driver? try getting the driver for the monitor, did you loose the Operating system at some point, if so try a system restore to a date when the computer was working properlly prior to the malfunction. It sounds like it restored you to a time before the driver for that monitor was installed.

Acer LCD Monitor only displays "acer" logo


You are correct, it could be a power surge that has caused it.

Try this..
Unplug the monitor from the wall.
Remove all the video connections at the monitor end.
Wait 10 minutes then plug the monitor back into the wall (do not connect the video leads)

Turn it on and see if it goes past the ACER logo now. If so, replace the video cables and try the computer.
If not, then one of these will apply and a tech will be required..
  1. The internal bios has been corrupted.
  2. The power supply inside the monitor may have issues preventing the video board from starting correctly. This could be as simple as a few failing capacitors.
Number 2 is the most likely cause with an Acer monitor though. Any local tech will be able to correct it fairly cheaply, but phone around for quotes..they can vary a lot.

Acer AL1716 Power problem?


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.
