Slide 33
1. After receiving the power on command from the power switch on the TV or the remote control:
2. IC8000 outputs the F_STB_ON command (DC1.5V ~ 3.2V).
3. F_STB_ON is applied to pin 6 of connector P6 on the P board to be connected to the power micom
(IC502).
4. IC502 outputs 2 switching signals to:
1
st
Turn on the switching circuit to allow the triggering of the relay RL100. AC flows now through the
relay’s contacts.
2
nd
Turn on the switching circuit to allow F15V and S15V to be output to the A board via connectors
P6/A6.
5. The S15V is applied to the audio amp. ICs (IC4900 and IC4901).
6. The F15V is applied to a DC-DC converter circuit to generate the SUB Voltages.
7. The SUB Voltages are used by the A board for signal processing, the K board for CATS (Contrast
Auto Tracking) operation, the bluetooth module, the C boards, and the panel.
8. The sub voltages are also provided to IC8000.
