What to do if Mitsubishi Electric Projector says no signal?
- TTeresa RobertsAug 2, 2025
If your Mitsubishi Electric Projector displays “NO SIGNAL”, ensure the connected device is powered on and functioning correctly. Verify that the external device is outputting signals and that the cable connecting it to the projector isn’t defective. Confirm that the projector is connected to the external device using the correct terminals and that the connected device is correctly selected as the input source. If you're using an extension cord, replace it with the supplied cable to check for proper image projection. If the image is then projected correctly, use an RGB signal amplifier along with the extension cord.
