Try looking at the LCD screen at a sharp angle to see if ghost-like video can be seen during the 'off' time of the flicker.  If video is still present even though not that visible, then either the backlight or its power supply are failing. The color problem could also be caused by a backlight lamp that is not ionizing completely.

Sounds as though you have a backlight issue. How old is the monitor?
The keyhole with the lock sign is for a security lock to lock the monitor to a desk so it cannot be stolen.

ACER AL1706 powering up, green power light flashes once a second, faint 'flicker' on screen, eventually starts up with the Acer logo, and runs normally.


You may have dying power supply due to bad DC filter caps.
Please see failed ACER and other monitors to see if you will want to DIY repair.

Monitor flickers and goes blank after 5 seconds and keep repeating this very often.


Hello,

If you turn the monitor off then about 1020 sec turn it back on and have a picture for five sec again it sound like the power supply in the monitor. but if that did not solve the problem, the picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault and will need to be replace.

I advice you replace the picture board on the screen of your monitor to solve the problem of the blank screen.

Take care.

Acer AL1716 monitor flickers


i Have the same problem, this screen is used on the spare computer we have in a loft conversion and the room does get rather cold, Warming the screen up with a fan heater for a couple of minutes gets rid of the problem. When the fault occurs the buttons on the front to adjust the picture quality don't work they just turn off the monitor.
