SUB-Voltages Output From the PA Board

When FSTB14V is applied to the PA board through PA10, immediately a set of voltages is

developed, lasting only approximately 15 seconds after AC has been applied to the TV.

These voltages are: SUB9V, SUB5V, and SUB3.3V.

The SUB9V and the SUB5V are used by the DG board and the DT board. The H board also

uses the SUB9V and the SUB5V, in addition to the SUB3.3V.

Unlike the previous models, the BT30V is developed in the H board instead of the PA

board. The SUB9V is applied to a DC-DC converter that generates the BT30V on the H

board. The BT30V is provided to the DT board through connectors DG1 and DG22 on the

DG board.
