Warning: Never remove the cover from the monitor as you may come in contact with hazardous voltage levels capable of causing serious injury or death.
Symptom:
If there is no image on the screen, but the monitor's power indicator light DOES come on, follow the steps listed below in order. You may not need to perform all steps listed.
Procedure:
1. Make sure any energy saver program on the computer is disabled if possible.
2. Make sure the ADB and monitor video cables are connected securely to the computer and the thumbscrews on the video cable are tight, also ensure the keyboard cable is connected through the base of the AppleVision display.
3. Make sure the contrast and brightness user controls are set correctly. The contrast and brightness user controls are on the front of your monitor, just to the left of the power button.
Note: If the display is connected to a Macintosh, before performing the next step you must first shut down the computer and monitor. Disconnect the monitor's ADB cable from the computer then plug the keyboard directly into the computer.
4. After the computer is finished powering up, press the user control button second from the left (it has an arrow pointing to the right above it) and second from the right (it has a '-' sign above it) alternately 5-7 times. This will alleviate the possibility that the microprocessor inside the monitor has a corrupt color mode causing the image to appear black.
5. If you are using a Macintosh, make sure your computer is using AppleVision Software version 1.7.1 or later. To find the most recent version of this software, please consult the Apple Software Updates Library available at
http://www.apple.com/swupdates.
6. With the most recent version of AppleVision software installed, restart the Macintosh and hold down the Command-Option-A-V keys simultaneously while the computer is booting up. Continue holding these keys down until you hear an alert sound or the image is restored on the display. This will reset the microprocessor inside the display and should restore the image.
7. If the display still does not present you with an image, it may need hardware service by an Apple Authorized Service Provider.
