If your Sharp Projector isn't displaying a picture or producing sound, and it won't start, here are a few potential reasons: * The projector's power cord might not be properly connected to the wall outlet. * External devices connected to the projector may not be powered on. * The lens shutter could be closed. * The selected input mode might be incorrect. * The AV Mute function may be enabled. * Cables may be incorrectly connected to the projector. * The remote control battery might be dead. * External output may not be set when connecting a notebook computer. * The lamp unit cover might not be correctly installed.
