The circuits normally found in the D board on previous models, are now built into the A board. This circuit provides the voltages necessary to drive all the circuits in the TV. This circuit is designed to perform all the functions necessary to process any input signal.
It communicates with other components on the TV via the bus line. It also provides protection by monitoring the supply voltages for abnormalities. This circuit provides the control drive pulses to the drive circuit boards to drive the panel. The STB5V is applied to a 3. The power command from the power switch on the S board or the remote control receiver on the K board is provided to the Main CPU on the A board thru connector A1. Panasonic has been using single scan addressing in our standard definition SD Plasma TVs for a while now.
Both the DG board and the H board are no longer used. The circuits found in these boards are now part. Also a red light from the Optical jack on the back of the TV can be observed. Approximately 15 seconds later, the click sound from the relays can be heard again and the red LED inside the Optical jack turns off.
This condition is normal and by paying attention to this sequence of events, we can confirm the operation of several circuits inside the TV. AC is applied to the power supply board P through connector P9. The 3. The STB3. The function of the 2. The 5V is also provided to the SS board. To avoid catastrophic failures, they are monitored by an SOS Detect circuit for over-voltage and overcurrent conditions.
