      If the LAMP/COVER indicator lights up on your Sony Projector, it could mean the lamp has reached the end of its life and needs replacing. It could also mean the lamp has reached a high temperature; in this case, wait 45 seconds to cool the lamp before turning the power on again.

    Why does my Sony VPL-CX21 Projector show no picture?
    • T
      Thomas CervantesAug 20, 2025
      If your Sony Projector shows no picture, first ensure all cables are properly connected. If you're connecting a computer, and it's DDC2B compatible, turn on the projector after connecting it to the computer, and then start the computer. Also, verify you've selected the correct input source using the INPUT key. Finally, ensure your computer signal is set to output to an external monitor only. You may need to adjust your computer settings or press specific keys to switch the output.
