What to do if my Mitsubishi WD570U shows no signal?
- Mmatthew33Aug 19, 2025
If your Mitsubishi Projector displays no signal, first turn on the power of the connected device or check if there is something wrong with it, especially if it's a notebook computer. Verify that the external device outputs signals and that the cable connected to it isn't defective. Ensure 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 using an extension cord, replace it with the supplied cable to check if images are projected correctly; if so, use an RGB signal amplifier with the extension cord.
