Please read below and look at the pictures of failed ACER before DIY repair.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, 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 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.

Monitor won't go on blue power lite won't change to orange. don't know if its video card or monitor


This is easy to test - disconnect the monitor from the pc and start it alone. If it doesn't start and show the no source warning then it's the monitor, it has an internal fault. It will be cheaper to buy a new one than to try to fix it.

Hi...there,
It's seems you got a defective DVI card. Try using a VGA cable instead. Have nice day!

Monitor keeps blank even the power lLED is on green


If it's working fine in DOS, it can only be your display drivers for your operating system. What happes when you start in SAFE MODE? When you PC starts, keep pressing the F8 key, go to Safe Mode. If it works, bring the Resolution down to 800 X 600 and load the new display card drivers. Restart, should be fine.

Monitor black


refixed all cables connecting to monitor. then start,

if you are sure that the monitor is ok, then these are only things to test

check memory and fixed it very well, then start, if the same problem,
check Video card and fixed it very well, then start, if same problem,

examine processor and motherboard. by doing this, you should remove the memory and start the system. if produces long beep means memory and processors are good.

there is no other thing to examine on this matter.

It sounds like either an internal wire is loose, or possibly in the connector to your video cable. Make sure the connections for your video cable are tight both at the computer and at the monitor. If they are, try a different cable (cables are much cheaper than monitors, always start with the easy solutions first). If the problem is internal to the monitor, then it is up to you to decide whether to try to diagnose/fix it yourself, or buy a new monitor. The cost to pay someone else to fix it is likely more than the value of the monitor.
