Kvo Praim wants answers to this question
is this a 2018 post? hijacked, sure.
V193HQV (street value good $26 , $0 bad)
why not start your own post, jacker.? with your facts?
and your details, of that the monitor does good bad or ugly
all facts you see matter, in all cases.
does the power button LED (on/off) power lamp go out?
or change color, (if change color that is sleep mode, due to PC issues)
does the monitor button marked, menu , work?>
when it turns itself (seemingly )off? if you push menu
and the acer logo pops and menu next that is not a dead monitor.
the monitor also shows errors for any lost of signal from the PC.
all monitors made do that, if not dead. (menu tests)
10 year old monitor today 2008 built.(as old as)
Some Old monitors have and internal sleep timer, that turns its self off. ( I RTM read your manual for you, and does not have this feature)
I can only assume the unstated failing PC, you tested the failing monitor on known good PC first, right, and I will respond in that way a bad Monitor.(fails on 2 good PCs)
bad monitor or configured wrong, is the cause.
Bad news: (always)
this old monitor has CCFL back lamps
your "W" model is wide screen but is not LED backlamped back in 2008, not until 2010
did LED happen.
so if the power lamp stay on, and screen is dark
use a flashlight pointed it the screen (dark room helps)
see data on the screen? or while pushing menu button over and over. that is bad CCLF. lamp tubes inside,
ive posted this set of facts here 100s of times.
this monitor has no sleep timer clock like I mentioned above.
ACM (Adaptive Contrast Management) (turn this off)
and use the menu to pick RESET, so it goes back to factory settings new. are you only 2 choices besides brightness and contrast, if screen is only dim.
Now the SAID rules of CCFL lamps.
intermittent as H3LL (your case) sure.
and white looks yellow....
most are dead now, this old, upgrade to LED monitors.
