Hi!
The reason why the button of your monitor flickers is because the 12 volts output supply for your inverter board is not stable..
If you have the skills and the right tools for this, Here's what you need to do
1. If your monitor comes with a power supply adapter, open it..check and replace blown capacitor with same value..
2. If your monitor is using a cable power cord..open the back cover of your lcd..on the power supply section.. check and replace blown capacitor.
3. Check and resolder the terminals for fixing possible loose connections.
4. On the inverter board section...check and resolder the terminals for fixing possible loose connections, the high voltage inverter usually loose connections when overheat.
5. Other things to check if step 1 to 4 did not resolve your problem. Check and replace burnt high voltage transformer.. Check and replace busted backlight inverter..

Hope this fix your problems..

thanks.. much appreciated if you rate this help.

Screen Went Black


If you want to fix it, then you will need to buy some tools and basic knowledge of electronics, common problem with this monitor is the failed transistors and fuse in the inverter circuits, see pictures here as a guide: http://s807.photobucket.com/home/budm/allalbums
I would give the monitor to someone that is learning electronics to practice troubleshooting.

Monitor went black


Same with mine a couple days ago. I've been told the contacts have oxidized and need to be cleaned. It was going to cost about $80 to fix and no guarantee how long it would last so I just bought a new monitor.

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.
