Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, falied inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what goes wrong: http://s807.photobucket.com/home/budm/allalbums

Try to do this: Just before the Windows start up screen (after the bios loading) press F8 and log in at safe mode settings. If at this mode you can see your screen change the resolution settings at a lower set. Save and reboot normally. Now try step by step to increase your resolution. In case of a blank screen appears at a new setting, don't do anything; after some seconds the monitor will come back to the previous settings. Save and go on.

In case of a problem or clarification, don't hesitate to post.

Screen blank


Sounds like its simply going into power save mode. Does your screen come back on when you move the mouse or press a key on the keyboard? Is the computer still on? Check your power options in control panel.

Computer monitor goes blank after initial start-up reaches the desktop


Try setting your graphics card output to something simpler like a basic 640x480 resolution 64k colours and see if it still does it... it maybe that you have the resolution/colour depth to high for the monitor to properly handle

if it is stable at the lower setting slowly increase untill you reach a point that you and your monitor are both happy

Monitor goes blank after 5-10 minutes


You may have a compatibility issue with your monitor. You computer may not be putting out enough power to support your monitor. Check your users manual on your monitor for output requirements. If the monitor's manual has a number to call, call the manufacturer to see if there are any compatibility problems between your computer and your monitor and calling the people who built your computer as well. Get as many scenarios as you can to find a solution. Hoped this helped.

Acer AL1711 17" LCD Monitor goes blank without warning


The need to reboot your computer to get your monitor working places the blame totally in the computer. You have a virus, or the computer is overheating and shutting down for thermal reasons.
