Note: Some projector issues are actually issues with the Lectern Display or HDMI connections. 

If the projector is on (Green LED on the projector) but is displaying undesired content (black screen, wrong image, etc), 

please refer to the Lectern PC Display Issues article, or the Connection to an HDMI via a Laptop article for further help.

Issue 1: Projector Power Not On

Symptoms:

- The projector screen remains blank.

- There is no response from the projector when trying to display content.

- The room's AV system appears to be functioning correctly, but there's no projection.

Troubleshooting Steps:

1. Check Power Connections:

- Check if there's any indication of power on the projector itself (lights, status indicators).

2. Remote Control or Projector Buttons:

- If applicable, try using the projector's remote control or physical buttons to power it on.

- Ensure the projector's remote control is functional and has working batteries.

3. Check for Power Switches:

- Verify if there's a physical power switch on the projector that needs to be turned on.

- Verify there is a power cable plugged into the projector.

4. Inspect Cable Connections:

- Double-check all cable connections on the wall, make sure they are plugged in.

5. Touch Panel Control:

- Confirm that the Extron touch panel is communicating properly with the control processor

(I.e. selecting inputs on the touch panel changes inputs on the switcher in the lectern, volume slider

changes volume in the room).

- If there are network or control communication issues, the projector might not respond to

commands.

Issue 2: Incorrect Video Mute Toggle

Symptoms:

- The projector appears to be powered on, but no video content is displayed.

- The "Video Mute" button's state on the touch panel doesn't match the actual projection

status.

Troubleshooting Steps:

1. Physical Check:

- Visually inspect the projector to confirm whether video content is being displayed.

- Check for any indicator lights on the projector that might indicate its status.

2. Confirm Video Mute Status:

- Press the "Video Mute" button on the touch panel to ensure that it's in the correct state.

- If necessary, press the button again to toggle the video mute status.

3. Check Signal Source:

- Verify that the correct video source is selected on the touch panel (e.g., HDMI, Desktop).

- Make sure the selected source is active and sending a signal.

4. Check Cable Connections:

- Examine the video cables connecting the source to the projector. Ensure they are securely

connected.

5. Control Processor Communication:

- Ensure that the Extron touch panel is properly connected to the control processor and

communicating without errors.
