• Check whether the external device output signals. (Check this especially when the

 

external device is a notebook computer.)

 

• Check that the cable connected to the external device isn’t defective.

 

• Check that the projector is connected to the external device using the correct

 

terminals.

 

• Check that the connected device is correctly selected as the input source.

 

• When an extension cord is being used, replace it with the supplied cable and check

 

whether images are projected correctly. If images are projected correctly, use an RGB

 

signal amplifier along with the extension cord.
