Display Symptom Charts
Display
LED on the display bezel does not light up
Note: The LED does not light up when the power is on; however, the LED should pulse when the computer
is in Sleep mode.
1. Put the computer into Sleep mode. Does the LED pulse now? If yes, there is nothing wrong with the
LED. If no, replace the display bezel (922-5297). The LED is attached to the display bezel and cannot
be ordered separately.
Display Tilt
Screen tilts to the left or the right even after a manual adjustment.
Note: It is normal for the screen on an iMac (Flat Panel) to have a small amount of horizontal play.
However, the screen should be able to be adjusted so that it will stay in a level horizontal position.
1. Remove ten screws connecting the back cover to the flat panel LCD display (refer to the Take Apart
chapter, display topic).
2. Disconnect the panel cables to gain access to the three screws on the metal cable retainer (shown in
the middle of the picture below). Remove the screws and lift the cable retainer off the panel shield.
