TC-L37DT30 Voltage Distribution Explanation
The TV SUB On command of IC8000 triggered the P-Board into supplying +16V to the A
board.
The +16V source, also known as the P15V, is supplied to numerous DC/DC converters to
produce SUB and MAIN voltages.
On the other hand, the DC/DC_EN command from IC5000 triggers several DC/DC
converters to produce SUB5V, USB5V, SUB3.3V, SUB1.5V and SUB1.2V for
the operation of the A-Board, KA-Board, and S-board. Some of these voltages are monitored
by IC5000 and IC8000 for their presence. If one of the monitored voltages is missing, a
shutdown is triggered and a blink code generated.
The 3D_LED_ON command of IC8000 turns on the LED_DRV5V DC/DC converter
to power the 3D IR Transmitter used to synchronize the 3D glasses.
A SUB9V source is also created by a DC/DC converter located inside IC5000. This voltage
is applied to the AV Switch IC.
Provided by IC8000, the panel VCC-ON command turns on the Panel 12V DC/DC converter
to produce 12V for the operation of the T-CON circuit.
