I have an Acer LCD AL1914. It is 14 years old and has CCFL back lamps and fails on 2 PCs, and the cable is not bad. I am told another CCFL 2003 monitor bites the dust, is it?
Try connecting the wires properly. try changing the VGA cable. i had the same problem my screen goes black some times and pink i changed the VGA cable it was absolutely fine!!!
What is VGA cable
VGA Cables Adapters Converters and Devices C2G
visit a computer mechanic for further trobleshooting
actually this is more easy.
that old monitor has bad CCLF back lamps.
all do this old. (age matters here)
if the monitor fails on 2 PCs the monitor and sure the cable are bad.
1 test and no more silly guessing .
no manual at acer.com now.
but shows 2003 year stamps. oops PRE LED era.
but the main PSU board for it clearly shows CCLF power jacks
the older monitors have (pre 2010) had a monitor sleep timer inside, we turn that off first, setting monitor to defaults in the oSD also turns this silly old sleep timer back on, yah silly.
I found a manual in the dark web
shows no sleep timer INSIDE it. GOOODDDDDDD
The trick is use a flashlight.
buy one use one.
point it at the black screen in a dim room
see data how, bingo, CCLF ***** has arrived
as all are now every one, no parked in attic for 5-10 years.

the magic of a $2 flashlight test is here

it's now 16 years old. (a good run be happy)
2003 to 2019
so buy one 2010 or newer and CCLF are gone and LED runs forever mostly.
back lamps topic.
ALL CCFL 2009 and older monitors are dead now. if used 8 yours a day for 5 year the CCFL tubes (trash lamps) die.
they go dim
or dead.
go yellow
blink.
or work one day not next or 1 hour and not next. all do that now.
we put them out to the trash,
or spend 2 times cost of this.
$46 gets you one that is good.

SOURCE: ACER AL1914 LCD Monitor goes black but green light stays on
The monitor is doing a self test a finding an error.
The lcd has three parts, the screen plate(windows)/the logic(vga)/the
inverter(power plug). Parts that go are the backlight ccfl's, behind
the plate, and parts of the inverter, ie capacitors, all three take a
bit of power from the inverter. The self test check that all the lights
are ok and the inverter is ok, else it switchs off, ie if 3/4 light
work it will switch off(my own case), hence the on chech error then
off, However sometime there are stages of on/off ie on/ but no screen
display, if that is the case the following may be of help...if you put
bright light at an angle close to lcd can you see a windows shadow,
text icons etc, ie still logic power passing,then .... (from a.n.
other) after two weeks searching I finally find doctor living stone

the takening the case bit off is like opening your wallet a second time
after buying a new LCD, but you must! smallest two screw driver's flat
headed, practice using two pennies stuck together()with your fingers
after, one little () move and inch and {} again, with the case , it
does not break, just need to lever open
[once open you realize they somehow put that old briefcase clip
inside!] also note the bright light test to do first to see if can see
a windows screen , and that capacitors are one for a number of things
that a make a inverter work! there a transistors as well, given that
however, to replace all the capacitors on my inverter, was 11
capacitors, cost me $11 (uk ebay) and already had the iron and solder.
So only cost me me $11 to try and see but no luck , still fun and I
still can see the screen for 2 sec' at a time plus I have a spare set
of caps now in the event that the new one do go burst! you have to
laugh really, what next , a new on/off button, as you work though the
whole inverter mmmMMMMmmmMMMMmmmMMMMTim
Berners-leeMMMMMmmmmMMMMMmmmmcome back all is not
wellMMMMMMMMMMnnnnnnweek later land sight
mmmmmMMMMMMMMMmmmmgggggggg(from
another a.n other)Generally, if the screen went out quickly, it was the
inverter. If it went out over a slow period of time (flickering etc..)
I would bet it is the lamp.replaceing the lamp should be pretty
challenging. as that requires complete breakdown of your LCD,
extraction of your dead lamp, and soldering in your new lamp... but I
would like to say that I it did this after realizing it's 2 x kitchen
strips inside [========] with wires that can connect back to the
inverter with out any desoldering(ie kit assembly/dis) with the outter
case remove (glass plate safe away) I could reconnect and see that 3/4
were working (i!i hardcard ) cause the inverter to switch off after a
secound ! order bult and replace and going
to cheap and see if I can get away with fitting a 15" in my 19' as it a
1/3 of the price ! the market as drop out there, hope the inverter does
not miss the length, or the screen out
put.http://www.lcdparts.net/howto/troubleshooting/LaptopCCFL1.aspx OR

Exact same problem on my AL1914.
I have the same problem. Turning the monitor off and on over and over it will finally stay on. worked a few times after rebooting now won;t come back on at all. Just will flash for a second showing the desktop. I was told it could be the video card. I will try changing the card this weekend. I have a viewsonic monitor though.
