The screen is blank and won't power on. When I plug in the computer USB cable, the computer shows an error message saying something is wrong with the USB device. Is it a throw-away, or is there somewhere I can send it to be repaired?

Acer produces a number of LCD computer monitors. Acer's monitors range from 17 inches to 27 inches. Some monitors offer wide-screen viewing, embedded speakers, high-definition visuals, and various display connection ports. Acer computer monitor problems include common issues such as dead pixels, error messages, and blank screens caused by incorrect connections. Some reviewers have also detected image problems with DVD playback on some models.
"Input Not Supported" Error Message Acer computer monitors such as the G24 may issue an "Input Not Supported" error message when users set the display resolution too high. The G24's maximum display resolution is 1920x1200 with a 60Hz refresh rate. Maximum resolutions vary according to the specific monitor model and according to the capabilities of the computer's video card. b> "Input Out of Range" b> Some Acer computer monitors may report an "Input Out of Range" error message due to incorrectly set monitor refresh rates. Much like the display resolution, each monitor also has specific monitor refresh rates with which it is compatible. Blank Screen or "No Signal" Error b> Like other monitors, Acer computer monitors feature color-coded power indicator lights. If the power indicator light shows green, the contrast or brightness levels may be set too low and should be adjusted via the OnScreen Display. If this does not rid the monitor of a black screen, the monitor may be experiencing hardware failure. The "No Signal" or "Check Cable message" may indicate a problem with the monitor's cable connection with the video card. This error may also appear on a blank screen backdrop if the monitor is plugged into the incorrect port on the computer or if the computer is frozen and needs to be rebooted. Faulty power cords or outlets may cause the screen to be black and to show no power indicator color. b> Image Issues b> Some review sites such as CNET have reported problems with streaking and ghosting during DVD playback on some Acer computer monitors such as the AL1931. (A "ghost" is an identical offset image as the primary or desired image.) Unstable or unclear image issues may be caused by incorrectly programmed VGA timings or incorrectly installed monitor drivers. b> Dead Pixels b> Dead pixels and sub-pixels can cause a variety of display enjoyment problems. Acer will only accept returns on LCD computer monitors that have "more than four (4) defective pixels per million pixels." Further, the central area of the monitor may have no more than one defective pixel. Acer does not differentiate in warranty terms between pixels and sub-pixels. Hope this helps.
At some point if you can get the computer to stay up for a while, you should go into control panel and check your
POWER settings. The other thing you should try if you haven't already is to shut the computer off and pull out the battery. Then after a minute re-install the battery and see
if that helps.
ps: If I come up with any ideas I will post.
check if you are getting an error message as carriage jam..if you get this message connect the printer directly to the wall outlet and then check for the error message..if it still the same..perform a reset on the machine..that is you need to unplug the power chord from the back of the printer, press and hold OK and CANCEL button together while pressing these two button plug in the Power chord to the back of the printer..after you plug in the power chord do not release those two buttons, keep pressing those two buttons untill the screen is blank..once the screen is blank release the buttons and then turn on the printer..check for the message..if you are still getting any error message then it is a hardware issue..machine should be replaced..
Be sure that the power cable and the video cable are plugged into your monitor, the power cable is plugged into a good outlet, and the video cable is plugged into your computer. It's possible that you simply have a loose cable.
If everything is installed correctly, and if the screen is completely blank (no "cable disconnected" or "test mode" messages), then it sounds like your monitor is simply dead. Since there was a heavy wind storm recently, it was probably hit by a power surge. If you don't already, I recommend that you use a surge protector for all digital equipment.
Unplug the cable from your PC, if the monitor shows a test image, the monitor is fine and the problem is with your graphic card.
If you dont see nothing on-screen after unpluging the cable from the PC, then the monitor in damaged. Send it to repair.
