Hi, I have had an AL1711 acer monitor for a couple of years now, and it never made any problems, until two weeks ago. Whenever I turned it on, the picture would be there for two seconds and then go out, although the monitor would stay on( the light is green). I would then need to turn it on 10 more times till it would have a constant picture, which would last till I turned it off again. Yesterday, when I turned it on, it started displaying weird lines and malfunctioning, as well as only showing for two seconds and dissapearing again. I've checked everything and it works, as I am writing now on a CRT monitor and nothing is wrong. What is wrong, and can I fix it?

Re: What is wrong with my AL1711
I have had one of these acer al1711 fail - goes blank after 10 minutes. When warm goes out after 2 or 3 seconds . I have another OK unit and swapped the two logic boards around. 1 board is the video driver other is power invertor. This did NOT fix the problem.
The issue is with the LCD itself or the Lightsource. I cannot make out an unlit image anywhere!
I may try to see if I can swap the lightsources around!
This is possibly an inverter. When the monitor goes out, examine the LCD to see if you can see a faint image of the video being displayed. IF so, replace inverter. If not, possibly a bad LCD or video circuitry.

A white screen indicates the power supply board is not putting out the correct voltages to properly power the monitor, just the back light. This type of issue is caused by a failure of the filter capacitors on the power board. You can rebuild your power supply board and bring the monitor back to life by just replacing the the bad capacitors. The problem is that model the Acer AL1711 could come with 1 of 4 different power supply boards install depending and the date manufacturer and supply on hand. If you want to repair the monitor if you could open the unit and get either the model number of the power supply board or send a picture of the board to me I will be glad to help you repair the unit and get it back up and running.

I just had this problem at work and what I did was I powered up the computer and went into the menu. I went to the 2nd to last button and selected the reset. It's working perfectly now. I do not know if it will last but it's easy and free.
This monitor has "back lights" that are essentially like flourescent lights. These are high voltage lights and can easily fail. since you are getting some light initially, I would suspect a defective part that heats up a bit right away and then fails. I would try to replace the entire backlight board. This is the small board on the side (usually).
My Acer AL1711 packed up last week, I bought a new Acer and noticed they have a 3 year warranty. Give Acer a call on 0870 853 1000, and they`ll do a warranty repair with free pick up and return - great service! Not sure if you need proof of purchase or not, luckily I had mine.
