I replaced the 470uf 25v capicitors and this fixed the problem. I had 2 monitors exactly same with the same problem and it fixed both of them.

There's a capacitor that's been overheating in the power distrubuting board. The light flashing means it tries to power on but the current is too unstable / wrong because of this one capacitor. I had the same problem myself with this exact screen.. It's a 470μ 25v capacitor.

Why is the power light on my Acer monitor flashing?


See this.. http://www.techsupportforum.com/forums/f25/acer-monitor-is-blank-and-power-light-flashing-green-318760.html
Also, here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

AL 1706 troubleshouting monitor wont turn on green


If your monitor shows a yellow light and it won't turn green, the problem most likely lies with the computer. If your computer is not sending a signal to the monitor, then you have a computer problem. One way to test this is to turn the monitor off and the computer off, too.
Turn the monitor on and if it is working, it should display a message telling you that there is no signal. If you see that message, you can assume the monitor is working. If you do see it, now turn on the computer and see if the message changes.
If you turn the monitor on and you get no message, you can assume the problem lies with the monitor itself.
If you have access to another monitor, hook that one up to test the computer output.

You can now either get the monitor fixed or the computer fixed, depending on which one is bad.

Acer LCD AL 1706 A monitor will not come on


The problem can be bad capacitors in the power supply, look for bad caps with bulging tops or seal, see example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further. To have it repiared by the repair shop will not be practical, est $60~70 repair bill.

Acer AL1715 power issues


I have an ACER AL 1706 monitor that would not power up completely. After pushing the power button, only the yellow light would stay on indication a power up fault. After careful inspection of the power boards caps, there was visible swelling of the 47mF and 22mF radial caps on the top part of the caps where the tiny cannisters 4 edges are folded down flat. I replaced these caps( 6 on my board) because there is reaaly no way to actually test them and bought new ones from Radio Shack. Now my Acer monitor came back to life with no other problems. I recommened using replacement caps with same microfarad values, but if the voltage rating is not exact, it is o.k. to get the next higher voltage rated caps available and should work fine.

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.
