F+15V/Sub-Voltages Distribution - Panasonic TC-P54Z1 Technical Manual

F+15V/SUB-Voltages Distribution

The F+15V from the power supply is connected to pins 23, 25, and 27 of connector A6 on
the A board
The F+15V from the P board is the source that supplies the DC-DC converter circuit
(IC25600, IC25601, IC25300, and IC25312). This circuit outputs SUB5V, SUB3.3V, SUB1.8V, SUB1.2V,
GC6-3.3V, GC6-1.8V, GC6-1.2V respectively.
These voltages are normally used in the DA board. Only the SUB5V and the SUB3.3V are used outside
the DA board.
The SUB5 is used is used by the HDMI board (GH) and the KA board.
The SUB3.3V is used by the HDMI board (GH) and the SD Card Slot board (SG)
A 10 blinks code from the power LED indicates abnormalities in any of these voltages including the
F+15V.
