There are a few reasons this might happen. 1) Check if the transport lock is in the locked position. Unlock the unit if it is locked.
2) An error occurred. Try restarting the computer, unplug the scanner, wait 10 seconds and reconnect the scanner. (This fixes issues where the software isn't running/fully loaded or the connection isn't solid).

Try a new USB cable and a different port. If you have a USB hub in the middle, try a direct connection. (Bi-directional communication is needed and this may show as an error if it is lost.)

3) Try unplugging the scanner from power and plugging it back in.

4) Try unplugging the optional accessories. If they fail, the unit may indicate a failure.

5) The lamp may need to be replaced.

6) Something else may have failed. Consider if it is worth having the unit serviced.

I hope one of these ideas helps.

No power output or display.green standby light flashes.


Sounds like either a blown mainpower fuse or the thermal fuse for the power transformer. If the protect circuit was kicking in, the display would light up, but then turn off with a red blinking light. the green light with no display means the transformer is not getting power.

Power Problem with 2Wire 2701HG-B


Sounds like a startup self test. All wireless devices go through a power on self test. Does it connect? You can connect to it and go online? I rarely turn mine off, only in a electrical storm.

Is the projector receiving a source signal? if not it will power itself down after whatever time you have it set to do so when no signal is present.

Powers on for only a few seconds


if the power light blinks and the status light is off, check the lamp door. if the power light blinks and the status light is steady red or blinking green, you have a power supply/ballast issue. you may have to send it in for repair. try www.avsolutionsny.com.
