Discoloration Issues - Hit the source search button on the projector remote (or change the input to a different source and then back to the one you are using), the purple screen/discoloration could go away when the image resets.
All Issues...
- Tighten the cords on the back of the Elmo and on the wall connection.
- Check the small switch on the side of the Elmo to ensure it is on the projector settings.
If needed, please create a HelpDesk ticket for the building TA to troubleshoot further for you. Note if the issue is also happening when using the Apple TV.
Building Techs ONLY:
If the above does not resolve the issue, try the following...
- A new VGA Cord
- A different Elmo
- Connect the Elmo directly in to the projector to see if the issue still occurs
- Create/Transfer Helpdesk ticket to the AV Queue with the steps you have taken and the results if the issue is not resolved.
