Note: in some instances restarting the panel may resolve the problem

Screen

Problem Solution
The electric screen will not come down
  • Check the control panel is on
  • Where appropriate, ensure the [Source] or [Screen Down] button has been selected
  • Check if it is a manual screen which needs to be pulled down
  • Check if it is an electric screen controlled by a switch on the wall

Projector

Problem Solution
The projector does not work
  • Check the control panel is on and has warmed up (you may need to wait a minute)
  • Check the projector has a green light indicating it is powered
  • Check you have selected the correct source
A lamp or filter warning message has appeared on screen
  • The message should disappear shortly, if it does not contact the IS Service Desk

PC/laptop

Problem Solution
The PC does not work
  • Check the light on the pc indicates it is powered
The PC displays an LDAP error when trying to log in
  • A re-boot of the PC may clear the problem
The PC/laptop image is not projected
  • Check the correct source is selected
  • If trying to display the PC, ensure that there is not a laptop already connected to the system
  • If trying to display laptop, check the laptop is set to display a dual image. The command for this varies between models but is generally one of the function keys.
No sound from the PC
  • Check the sound on the control panel has not been set to 'Mute' or low, e.g. '0'
  • Check the audio icon has not been muted

The Wolfvision unit has gone to sleep:

  • The Wolfvision units automatically turn on/off as the arm is raised/lowered.

  • Check the correct source is selected
    • In some rooms the 'INT/EXT' button is used to switch between a laptop and the visualiser
  • Check if the lens cap has been removed
  • Check the power green light is illuminated?
    • Turn on the panel power
  • Ensure the correct lamp illumination is selected, e.g. cycle through the settings to check
  • Check there is a cable connected to the 'output' located at the back of the visualiser
The image is out of focus
  • If available, use the [AF] button to autofocus
  • If available, use the [+] and [-] buttons to focus

The DVD/Bluray does not work
  • Check the panel is powered on and the correct source is selected
  • Check the 'Unit Powered' is on
There is no sound from the DVD

Lighting

Problem Solution
The lighting levels will not adjust
  • Select the lighting button on the control panel before trying to adjust the levels
