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

This model AL2017 20" Acer monitor is known for having a bad power inverter board. The capacitors go bad, which causes the backlight to completely stop working or flicker intermittently. If you feel like you are electronically and mechanically inclined the board is easily replaced. Search ebay for AL2017 Power Board -- its about 15 bucks plus shipping.
I CAN FIX THIS or rather you can there are a total of 5 capacitors in the screen Power Board, that upon inspection the ends are bulging therefore they are bad. So do this: go to Radio Shack or similar store that sells capacitors and buy (3) 220 Microfarad capacitors Radio Shack Part Number 272-1029 and (2) 1000 Microfarad capacitors PN 272-1032. now on your board you will see the bulging capacitors just remove them and replace them with the new ones. PAY CLOSE ATTENTION to the polarity, there is a negative stripe on the side of the capacitor. Make sure it goes back in the way the old one came out. Now the radio shack capacitors are 35vdc and the stock capacitors are 25vdc and the new capacitors are bigger in diameter but the difference is ok as long as the Microfarads are the same. I preformed this and my monitor works Outstandingly well with NO problems yea I’m a happy camper.
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.
