Check power supply section for bad caps first.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, failed 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 ACER monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

LCD Screen blank

Hello,

The picture board on your monitor is bad, since the power led or button is on, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

Monitor Acer Al 1914, no signal

Check your connections to the PC. Make sure that they are nice and secure. If there is a resolution problem setting it should display the boot process and then go blank after starting the operating system.

Screen Goes Blank

Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.

Acer AL1914 black screen, green light

it sounds like a deleted driver? try getting the driver for the monitor, did you loose the Operating system at some point, if so try a system restore to a date when the computer was working properlly prior to the malfunction. It sounds like it restored you to a time before the driver for that monitor was installed.

Acer 20" LCD AL2017 does not give a picture @ all.

You can look on eBay for BACKLIGHT FLUORESCENT BULB for your model.

They're around $20.00.

Blank Screen..Will not power off

The flash light test only works with lcd monitor as they have back lights. Double check the connections again, also, if you can borrow a monitor try it on your pc, it may be your graphics driver needs to be uninstalled and re-installed, but you will need a monitor to see.
