It is always on in a PD dispatch area connected to UPS (with no errors on it). screen went blank during fire dispatch put a new monitor in place using a different power source and it worked fine.
Put the al2017 on the same new power source and it worked fine....
Put the new monitor hooked up to the power cord the al2017 was on and it worked.
Put the al2017 back in place using the original power source and it worked....for a minute then went black (no leds) and would not work even on the new power cord in a different power source.
Pannel seems hot. Walked it back to my office...few minutes later so it had a chance to cool down and now is working fine in my office.... I am leaving it plugged in an always on to replicate but may have to return it to acer...any other thoughts?

Re: Had a Acer al2017
If your picture was okay when it was running and the screen was not pinkish then the power board inside the monitor is in need of an overhaul. Your unplugging it and plugging it back in just did a temporary reset by discharging the capaciotrs for a bit. It more than likely needs new capacitors installed. I have done a few of these and do a lot of inverter power board repairs through ebay id bammbammfran Fran firstname.lastname@example.org

Acer produces a number of LCD computer monitors. Acer's monitors range from 17 inches to 27 inches. Some monitors offer wide-screen viewing, embedded speakers, high-definition visuals, and various display connection ports. Acer computer monitor problems include common issues such as dead pixels, error messages, and blank screens caused by incorrect connections. Some reviewers have also detected image problems with DVD playback on some models.
"Input Not Supported" Error Message Acer computer monitors such as the G24 may issue an "Input Not Supported" error message when users set the display resolution too high. The G24's maximum display resolution is 1920x1200 with a 60Hz refresh rate. Maximum resolutions vary according to the specific monitor model and according to the capabilities of the computer's video card. b> "Input Out of Range" b> Some Acer computer monitors may report an "Input Out of Range" error message due to incorrectly set monitor refresh rates. Much like the display resolution, each monitor also has specific monitor refresh rates with which it is compatible. Blank Screen or "No Signal" Error b> Like other monitors, Acer computer monitors feature color-coded power indicator lights. If the power indicator light shows green, the contrast or brightness levels may be set too low and should be adjusted via the OnScreen Display. If this does not rid the monitor of a black screen, the monitor may be experiencing hardware failure. The "No Signal" or "Check Cable message" may indicate a problem with the monitor's cable connection with the video card. This error may also appear on a blank screen backdrop if the monitor is plugged into the incorrect port on the computer or if the computer is frozen and needs to be rebooted. Faulty power cords or outlets may cause the screen to be black and to show no power indicator color. b> Image Issues b> Some review sites such as CNET have reported problems with streaking and ghosting during DVD playback on some Acer computer monitors such as the AL1931. (A "ghost" is an identical offset image as the primary or desired image.) Unstable or unclear image issues may be caused by incorrectly programmed VGA timings or incorrectly installed monitor drivers. b> Dead Pixels b> Dead pixels and sub-pixels can cause a variety of display enjoyment problems. Acer will only accept returns on LCD computer monitors that have "more than four (4) defective pixels per million pixels." Further, the central area of the monitor may have no more than one defective pixel. Acer does not differentiate in warranty terms between pixels and sub-pixels. Hope this helps.
I had a similar problem, but I got a picture before it broke up and went off. The screen was backlit, but no video (screen was receiving some power).
The LCD needs a very stable voltage to work, this is provided through the LCD connector ribbon. In my case the ribbon was damaged and replaced it.
I have had no problem since.
I discovered this through trial and error; I first changed my transformer power supply and then the video inverter card.

I repair monitors
Based on other models , it sounds like you are having a powerboard-inverter issue.
It just so happens that I hjust got one in that's doing that, I should
know in a day or two (maybe sooner) what the whole story on this model
Good timing !!??
I just repaired one.... will likely require that you replace 3 X 220 uf 25 volt capactiros and 2 X 1000 uf 25 volt capacitors. can't miss them the tops are swelled up. but the monitor appears to work now... not bad for 5 bucks worth of parts.
