How to fix a Mitsubishi WD385U-EST displaying 'No signal'?
- AamolinaAug 26, 2025
If your Mitsubishi Projector displays a 'No signal' message, first ensure that the connected device is powered on and functioning correctly. Check if the external device is outputting signals, especially if it's a notebook computer. Verify that the cable connecting the projector to the external device is not defective and is connected to the correct terminals. Also, confirm that the connected device is correctly selected as the input source. If using an extension cord, try replacing it with the supplied cable to see if that resolves the issue; if it does, consider using an RGB signal amplifier with the extension cord.
