Question about Acer AL1715 17 inch LCD Monitor

2 Answers

My AL1716 monitor does not power up on start-up. The green power light flashes, but no action otherwise. However, if left alone for a while it eventually comes to life. Is this a power supply failure, i.e. bad capacitors. Also, the problem manifested itself following a household move. I thought I'd packed it quite well, but it has not worked corrected since being relocated. Do I have an excuse for a new monitor?

The flashing green light with no display is a good sign that the backlight power supply is failing. Since it comes back on after a while, seems to me to indicate that it's a part that is out of tolerance and as the power supply tries to recover, starts to work. Probally it a capacitor that is going bad. Don't think the move would cause a problem. You could fix it by replacing the capacitors for less than $20. There is seller on ebay that just sells replacement capacitors for LCD monitors if you want to fix yourself, otherwise spring for a new one.

More likely to have bad caps, look for caps with domed tops, replace them in a set.See my pictures here: http://s807.photobucket.com/albums/yy352/budm/ACER%20AL1715b/

Hi, My Acer AL1716 monitor has stopped working and the light on it just keeps flashing. I have put a new power cable on it but still the same problem. I have plugged it into another PC and it still is not...


More likely to have capacitors failure in the power supply section, that will be the first place to check, see example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside when you open it up so we can guide you further.

AOC color monitor model 5En...during power on all led lights blinks then stops blinking without display action. all led lights on no more action observed.


actually if u repair an aoc monitor alone without getting connected to cpu once u switch on the monitor all led's will lit on ( green light ) it will remain on situation until u connect the vga connector to cpu that's the time led's will lit off and only the power led will remain in green condition.some aoc 5en once u power on power led is in green condition and if not connected to cpu it will be in orange condition.hope u get some idea but i am not sure if it will work with ur monitor. but as long as LEDs lit on i think no problem with ur monitor.

Acer AL1716 A Monitor does not start


Hello,

The problem on your monitor is a bad power supply. Because of heat buildup in LCD monitors parts called capacitors overheat and blow out. You can go to our web site at:
www.ccl-la.com/badcaps.htm and see what to look for. If you open your monitor and see blown capacitors that look like the pictures on our site then replace the bad ones and you should be back going. Email me if you have additional questions or if you need to get the capacitors, we carry them in stock.

I hope this helps, if so please rate my solution.

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.
