TOPIC



    I seem to have either no raster, or a dim raster on the screen of my AudioVision 14" monitor, how do I reset it?


DISCUSSION


    Do the following:
    1) Shut down the Macintosh.
    2) Turn the power off on the monitor and CPU.
    3) Disconnect AudioVision 14 Monitor power cable for 30 seconds.
    4) Reconnect AudioVision 14 Monitor power cable.
    5) Switch monitor back on WHILE holding down BRIGHTNESS UP and MICROPHONE
    buttons (these are the 2nd and 5th buttons from left, respectively).

    NOTE: On a Macintosh CPU which turns on the monitor automatically at power
    up, you will instead have to hold down the above buttons while
    powering on the CPU.

    Other situations when the monitor may have to be reset:
    * Sound control panel does not display the 'AudioVision' option in the pull
    down menu.
    * Unable to launch the 'Video' control panel, instead you get the message
    'The Video control panel can't be opened because no video panels are
    installed.'
    * When the '~AudioVision' extension boots with an 'X' through it
    * The Monitors control panel does not display any bit depth selections

    In the four situations listed above, merely powering down the monitor and disconnecting the power cable from the monitor may be sufficient, but the 2-button reset procedure above will definitely work in all cases where the monitor needs resetting. This 2-button reset procedure resets the CPU inside the Sound Module in the AudioVision 14 Monitor.

    In some cases, a sync problem between the monitor and computer may also necessitate resetting the monitor. The microprocessor in the sound module is responsible for processing the sense lines. If the video cable connector that plugs into the main monitor board is seated correctly and has no broken wires at the connector, resetting the monitor should be tried prior to replacing the sound module.
