My acer laptop display goes black when the power cord is connected

SOURCE: Laptop monitor goes black

it sounds like your display's backlight is going bad. Depending how handy you are, you may be able to replace just the LCD, they might have new or used LCDs on E-Bay.

SOURCE: My Acer 22" AL2223W monitor display goes Black

try hooking it up to another computer to ensure
it is not the graphics card that makes trouble...

if still the same prob, check the net if there are
known overheating problems for that model,
i personally recommend to see a technician, as repairing a monitor could make things worse...

up to u, good luck then

Look for caps with leaking/bulging top or have high ESR (Equivalent Series Resistance, need cap meter with ESR testing).
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, 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 SAMSUNG 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.

• Nothing is more annoying than a monitor that refuses to turn on. Make sure your Acer monitor is plugged in to a functioning outlet. If it's plugged into a power strip, try replacing it with a new one or moving the plug to a different outlet. Ensure that both ends of the power cable are plugged in firmly and securely, and that the connection to the monitor is not loose.
  

• Your Acer LCD monitor will usually accept DVI and VGA inputs. If you have an older computer, a VGA cable should work fine. If it doesn't have a VGA port, you'll need to obtain an inexpensive DVI to VGA adapter at your local computer store. A DVI cable, however, is compatible with most modern computers and offers superior picture quality over VGA. Make sure you're using the cable that's compatible with your system, and that you have the proper conversion adapter, if necessary.
