Why no image appears on Mitsubishi Electric XD490U Projector?
- PPeter PattersonJul 29, 2025
If no image appears on the screen, here are a few things to check: * Ensure that AV mute is off by pressing the MUTE button. * Verify the lens cap is removed. * Allow up to 1 minute for the lamp to light up. * If the lamp doesn't light, wait a few minutes and try again. * If the projector was turned off before cooling, wait for the fan to stop, then press the POWER button. * Make sure SCART INPUT in the FEATURE menu is set to OFF. * Check that the intake vent is clean and the lamp cover is closed. * Confirm that the cables connected to external devices are not broken. * If using an extension cable, try the supplied cable. If images display correctly with it, add an RGB signal amplifier to the extension cable.
