1)
Set the bus control data to the preset value.
2)
Connect #54 to an external power supply (PS).
3)
Turn the Y mute off (0), set the unicolor to the center (100000), set the brightness to the center (1000000), set
RGB cutoff to the center (10000000), and observe #13 (ROUT).
4)
Use unicolor to adjust the difference in the #13 picture period DC level to 0.7 V when the power supply is set to
V54 and V54+0.7 V.
5)
Applying V54+0.7 V to #54 as shown in the diagram below, calculateV1 of #13, then calculateV2 of #13 when
SW56 is on.
6)
Connect a 2-k resistor between #56 and C56 (1 F) and calculate V3 of #13.
7)
Calculate GDTC and GDTR from the following formula.
GDTC = ((V2 [V] V1 [V]) + 0.7 [V]) ÷ 0.7 [V]
GDTR = ((V3 [V] V1 [V]) + 0.7 [V]) ÷ 0.7 [V]
Note 1: When testing, see the picture sharpness test circuit diagram. First turn ACB mode off (bus control).
Note 2: Ensure the composite signal is always input to pin 38 (SYNC IN).
