6. Measure the brightness for the center box again – say Y2 fl
7. Pass the UUT if the Y2/Y1 brightness ratio is at least 1.4 times.
8. Turn off the bright window mode.
Note1: The “Vert Blnk DC” scroll bar should be at 0x8C and the “Delta DC Level” scroll
bar should be at 0x03.
Note2: If the bright window mode did not work, check that the length of the video cable
is not too long to cause any double image or power ON/OFF the DC power brick and try
again.
Degauss Check
1. Equipment: Hand degausser.
2. Condition:
(a) Timing format can be any of Cab_1 to Cab_7.
(b) Pattern is “Red Page” – select [Quantum Data>801 Patterns>Red Page].
3. Magnetize the UUT using the hand degausser by press/ release shortly to magnetize
the UUT at about 10cm away in the center of the screen. Screen should have some R,
G, B color patches.
4. Click on the “Degauss” button. The UUT internal degauss should be activated and the
screen should be just red without any color patches.
5. If the color patches remain then the degauss function is not working.
Turning OFF the UUT
When the UUT passes all the adjustments, click on the button “UUT OFF” and the UUT
will just shutdown. Important note: Must click on the button “UUT OFF” to power
OFF the UUT after adjustment. Failure to click “UUT OFF” will result in higher power
consumption in sleep mode and abnormal power ON operation (i.e. degauss activated
before powering ON the Mac) when connected to a Mac CPU.
