If it is a 1908pf, it is classed as a 19 inch monitor, not a 17 inch. Notwithstanding, the device is approximately 8 model years old, which makes it a senior citizen for computer monitors. Most likely candidate is the ballast (inverter) for the backlight system going bad, or the florescent backlight bulb itself is failing. These CAN be repaired, but as old as this unit is, you are better served buying a new one. Modern TVs/monitors can only be expected to last a little over five years anymore. The backlighting circuits are their weak points. Manufacturers are not interested in improving this, since they want you to buy a new unit every 4-5 years, rather than every 10 years as was the case in the CRT days. "Planned obsolescence", as we like to call it, is not unique to TVs either. Newer appliances (fridges/ranges/dishwashers) are all being made "better", meaning all kinds of bells and whistles, but engineered to last half as long as their predecessors. Apparently we can't have it both ways.

Hi...there,
It's seems your LCD Monitor backlight inverter it burnt out. Need a new inverter. Have a nice day!

Hi Gaz,
First, verify the monitor is functional.
Monitor STFC (Self Test Feature Check)
Turn off the monitor
Plug the monitor power cord directly into the wall socket to remove any surge protectors or APCs from the troubleshooting equation
Unplug the monitor video cable from the back of the computer
Turn on the monitor
The floating dialog box should appear on screen against a black background.
If the issue appears during the STFC, the monitor is defective. What are the results please?

Hello,
The problem on your monitor is a bad power supply. We you can solder you should be able to repair it. If you check our site at :
www.ccl-la.com/badcaps.htm We have a monitor repair section with dis-assembly guides and repair procedures. I will post a Hanns-g guide tonight. This will show how to open and repair the monitor. We also have a repair parts kit available. If you don't want to do the repair yourself then we can do it for you, just email me if you have questions or wan tus to do the repair for ou.
I hope this helps.

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

The LCd panel may be damaged and will cause this problem.
Another thing is overheating of the GPU.
The LCD signal receiver can be goign on you.
The is also the possibility of a faulty inverter.
Only thing to do is service or replace. Test the unit on another computer, if you don't get the issue there then you know its a problem with the PC.
