====== If one or more projectors do not respond to the Crestron. ======
(These are notes after the troubleshooting call with Lyle Weber from Mechdyne on July 26, 2018 at 10am).

The best solution is:
  * Pulling the power cable on the projects, and waiting 3 minutes before plugging them back in.  We tried unplugging for 30 seconds, but that was not enough.
  * Once you plug it back in, go back to the [[crestron:service_menu|service menu]] and "Connection Status" tab.
  * Click the checkbox next to the desired projector, and then click "Connect" to try to get the Creston to find that unit again.
  * **Note**: It may take about 1 to 2 minutes for the Crestron to show a green box next to the projector (showing that it is communicating with the Crestron).  If you do not see a change, then try exiting that screen and reloading the connection status screen again.  
  * **Note**: The Lamp Hours will not appear on the Display Menu for about 5 to 10 minutes (even after the projector is back in communication with the crestron again).


You can confirm whether the Creston is connected to the projector by:
  * Access the [[crestron:service_menu|Crestron Service Menu]]
  * In the [[crestron:service_menu|Service Menu]], then touch the "Connection Status" tab.
  * There will be a list of projectors and green boxes on the left if they are connected.  If anything is diconnected, then there will be a red box.


Mechdyne & I discovered the solution above after trying these steps (to no avail):
  * Pulling the power cable on the Creston unit on the rack.
  * Using the "Crestron Tools" software for Windows.
  * Pulling the power cable on the projectors.
