Answers :

Look at the capacitors in the power supply. Replace them if they look bulged on wither side or leaking. Most likely it is the inverter (the flat object with copper coils about 2 inches long, 1 inch wide). Check the resistance with a multimeter to be sure its around 1000k on both pair ends. They supply the CCFL tubes with voltage. If one onthem is bad they are designed to shut off within 1-2 seconds. Note the inverter numbers and order the part from www.lcdparts.com. You won't get them anywhere as the parent company MoniServe makes the power supply board for Acer.

ACER Al1916W goes blank in 3 seconds. It shows ACER splash screen for a sec., the desk top for .5 sec, then goes black. There is a very high pitch squeel each time there is any display.
