Power Supply Outline for 42"and 50" Models

Figure 4
The PF board of the older Plasma Television models is now incorporated into the P
board of the GPH8DU chassis.
The function of the line filter is to block incoming noise from the AC outlet to the unit and
outgoing noise from the unit to the AC outlet. The basic operation of the new P board is
the same as that of the older Plasma Display Televisions.
The Standby circuit supplies STB5V and 5V for FAN SOS. The main circuit supplies
Vsus voltage for sustain and scan operations, Vda voltage for data drive (C boards),
15V for sustain, scan, and fan operations, and 12V for audio power. The F_STB14V is
used on the PA board to generate other operating voltages.
