3M™ Pocket Projector MPro120

A computer is connected to the projector but the projector will not display the computer’s image.

•Unplug the VGA-Audio cable from the projector and a white image with the 3M logo will display.

The projector is making a noise.

•The projector has a small fan for cooling the LED light source. The fan turns on and off automatically based on the projector’s internal temperature. The fan will turn on more often in warm environments or at high altitudes.

•The speakers make noise when the volume setting is 4 and nothing is connected to the projector audio inputs. This is typical. Reduce the projector’s volume setting to 0.

•The speakers make noise when the component AV cable is not correctly connected to the video device. There are two red connectors on the component AV cable. One is for the right audio channel and the other is for the Pr component video signal. If these connectors are switched, the projected image will appear green and an abnormal noise will come from the right speaker.
