Hello, I have to same problem. I returned my monitor to Acer but got it back unrepaired, they could not see the malfunction. But I kept on sending it back, until I got a new model. Now after 2 years I get the same thing with this monitor. But there's no warranty anymore, so I looked into the problem myself. I found out that inside the powercircuit board is connected to the mainboard through a 10pin connector. The 5 pins that are on the lowest row, show a trace of white powder, I suppose occidation. I sprayed a little of contactspray in it. I must say the problem is not gone, but much better. The problem shows not so frequent anymore and lasts not so long. At first the screen switched of for 3 to 5 minutes and came back on. Now the screen is gone for perhaps 1 second and returns. So I'm almost convinced the problem has something to do with the connection of the powercircuitboard inside and the mainboard inside, when the monitor heats up a bad connection occurs due to occidation of the 10 pin connector. If you find a solution that fixes the problem 100% let me know, please. Mario.

Sorry to have to tell you this, but this is common in LCD monitors. The reason that it is going black when it boots is for one of two reasons. You either have a bad power supply that powers your LCD or your LCD's backlight is blown. These can be repaired or you can purchase a new one. But if it goes black 9 times out of 10 is because the backlight is bad. These can be repaired!

SOURCE: Acer AL1716 Power problem?

i have experienced the same problem (power cycles on and off and on and off... nothing but Acer logo and black screen) on 2 Acer model 1706 A version 1706 Ab monitors both built in July 2006. Before the customer reported the 2nd monitor with the same problem, i sent the 1st one into Acer for warranty service (after testing in on 4 machines w/4 different video cards). They shipped it back with a paper saying the monitor was repaired. I returned the monitor to the customer and it exhibited the same symptoms (aka, not repaired). Could there have been a bad batch in July 2006? When I plug a new Acer AL1716 monitor into the same computers, I have no problems at all.

Hi...there,
Well...your backlight inverter are busted.... need replaced a new one or repaired it.

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 http://www.aplusperfect.com/articles/lcd_capacitor_repair more fun with paulbtorrent
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 MONITOR
