Troubleshooting AppleVision Recovery Utility for Malfunction During Startup or
AppleVision Recovery Utility for
Malfunction During Startup or Recalibration
Important: Disregard the rest of this section if you are using
Apple Display software 1.5.3 or later. With version 1.5.3 or
later, the AppleVision Recovery Utility is built in. To operate the
built-in recovery function, ensure the monitor’s video and ADB
cables are connected to the computer. Start up the computer and
hold down the keys command-option-a-v until you hear a system
alert or the screen image is restored. Apple Display software will
detect a “no video” condition at startup and will correct the
condition when the extension loads. If the screen is blank after
startup or recalibration, use the AppleVision Recovery Utility as
follows.
Symptom Sets
A small percentage of AppleVision 1710 and AppleVision 1710AV
monitors malfunction either during startup or immediately after
color recalibration.
When this malfunction occurs, the monitor can display two
different sets of symptoms:
Symptom Set 1
• No raster (black screen).
• Power indicator light is on.
• Rustling or crackling sound emitted when the monitor is turned
on or off. Note: This sound indicates high voltage is present. If
high voltage is not present, the Recovery Utility will not solve
the problem. In that case, refer to the symptom “No raster
(screen is black); power indicator light on” in this chapter.
Symptom Set 2
• Screen is one predominant color (magenta, green, red, blue,
etc.).
• Instead of being black, the left and right edges of the screen
might exhibit some luminance.
If your monitor displays either set of symptoms, use the
AppleVision Recovery Utility to correct the problem.
