Why my Sharp XG-MB70X has no picture and no sound?
- M
  Martha MillerAug 17, 2025
  If your Sharp Projector isn't starting, has no picture, or no sound, there are several potential causes. First, ensure the projector's power cord is securely plugged into the wall outlet and that any connected external devices are powered on. Also, verify that you've selected the correct input mode and that the AV MUTE function is off. Check the cable connections at the rear of the projector and replace the remote control batteries. If you're using a notebook computer, confirm that the external output is properly set. Finally, make sure the lamp unit cover is correctly installed.
