The INV_ON/OFF command (high) of the MPU, IC1100 of the A board, passes through the AP
and P boards before entering the LCD panel. On the LCD panel, it triggers the operation of the inverter to
produce the 120V AC that powers the backlight CCFLTs.
To avoid catastrophic failures, when the Panel_VCC_ON pin of the MPU goes “low”, Q7805 turns off.
Consequently, Q7806 turns on to disable the operation of the inverter.
