The AL1711 screen comes on and stays on for 3 seconds. The screen gives a 100% picture when working. Might work properly after X-number of ON/OFF swithing. Have moved the screen to an other computer, same result so it must be thr screen.

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. You can contact me to send the information at [email protected]
this could happen when there is a missmatch in the operating frequency (refresh rate) between both VGA card and screen, try to reset your screen settings to default, and set the refresh rate on your vga card settings to 60 HZ
The most likely cause is blown capacitors on the power supply/inverter board. Go to our web site at: www.ccl-la.com/badcaps.htm we have pictures of what the capacitors look like when the blow out. We also have some dis-assembly guides that may help you. Just open the back of he monitor and look at the board, replace all the blown capacitors that look like the ones in the pictures and you should be back going. The values hat you will need are going to be marked on the sides of the bad caps. Be sure to use a low ESR and high temp replacement or you will have to do this again in a month or two. We carry the proper caps in stock if you want us to supply you with them. The caps at Radio Shack will not do. When you replace the bad ones be sure to install the new ones with the polarity stripe on the side going the same direction as the old ones come out. If you have any additional questions just let me know.

Hi. I have no experience with an AL1711 but this sounds very much like the power supply problem that affects the AL1715.
If you understand electronics then you need to check the power supply for faulty components (there were two faulty capacitors in my AL1715). Replacements should cost about 10p each and however much time it takes.
Unfortunately if you're not into electronics then there's really not much you can do.
If you do take the back off then please post whether you can see any faulty components.
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).

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.
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.
