Images aren’t projected on the screen.	• If the projector was turned off before the lamp cooled down completely, the fan may start rotating. In this
	case, after cooling about 90 seconds, the lamp will turn on automatically.
	• Check that the cable connected to the external device isn’t broken.
	• When an extension cord is being used, replace it with the supplied cable and check whether images are pro-
	jected correctly. If images are projected correctly, use an RGB signal amplifier along with the extension cord.
	• This condition may occur when an inlet or an outlet is blocked.
	(If this is the case, the STATUS indicator lights red.)
	J Remove the object which blocks the inlet or outlet, and then perform the following operations.

	in this case.
	• Turn on the power of the connected device, or check whether there is something wrong with the connected
	device.
	• Check whether the external device outputs signals. (Check this especially when the external device is a note-
	book computer.)
No images (Blue back)	• 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 pro-
