Set the bus control data to the preset value.
Connect #54 to an external power supply (PS).
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 (R
Use unicolor to adjust the difference in the #13 picture period DC level to 0.7 V when the power supply is set to
