Board).
2. When pressing the Power button on the remote control or on the main body, PS_ON (Pin 5 of CN1002 of Main Board)
changes from High to Low.

is supplied to the DC-DC SMPS.
4. If the VS_ON signal from the Logic Board changes from Low to High, the Main SMPS supplies VS power to the X and Y Drive
Board through the DC-DC SMPS, and the screen displays a picture on it.
