Overview:

If you're having trouble with a projector that doesn't display any images, follow these steps to diagnose and fix the problem:

Select the appropriate input source:

• Use the projector's remote control or buttons on the device to select the appropriate input source (HDMI, VGA, etc.) compatible with the connected device.
• Verify that the source device is set to output to the projector.
• If necessary, reset the projector to its factory settings, which can usually correct setting issues.

Check for hardware information:

• Inspect the projector lens for obstructions or damage.
• Test different cables and remove damaged cables.
• If you intentionally explore these methods, you can often tell a difference and find a subject that doesn't show a projector image.
