If your Mitsubishi Projector displays 'NO SIGNAL', try these steps: First, ensure the connected device is powered on and functioning correctly. Verify the external device is outputting signals and that the connecting cable isn't defective. Confirm 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 see if that resolves the issue; if it does, use an RGB signal amplifier with the extension cord.
