4. Digital P.C.B./Tuner/Main P.C.B. System Diagnosis
(1) IC communication on the digital P.C.B. (CPU and Flash/DDR/HDMI, etc.)
< Diagnosis Result >
(2) IC Communication of TUNER System
< Diagnosis Result >
0 No trouble found on the digital P.C.B.
1 Communication error between CPU and FLASH/DDR.
There is a high possibility of parts failure on the digital P.C.B.
2 Communication error between CPU and HDMI-LSI,
There is a high possibility of parts failure on the digital P.C.B.
3 Communication error between CPU and FLASH/DDR, and between CPU and HDMI-LSI.
Take measures of above "1" or "2".
4 HDMI-CEC circuit is not worked properly.
There is a high possibility of parts failure on the digital P.C.B.
5 Communication error between CPU and FLASH/DDR, and HDMI-CEC circuit is not worked
properly.
Take measures of above "1" and "4".
6 Communication error between CPU and HDMI-LSI, and HDMI-CEC circuit is not worked
properly.
Take measures of above "2" and "4".
7 Communication error between CPU and FLASH/DDR, between CPU and HDMI-LSI and HDMI-
CEC circuit is not worked properly.
Take measures of above "3" and "4".
Other Try to run self diagnosis again.
0 No communication error between digital tuner and IC.
1 Communication error between digital tuner (OFDM/digital modulation IC) and IC.
There is a high possibility of digital tuner (OFDM/digital modulation IC) defect, or communication
failure between ICs.
2 Communication error between the digital tuner (LNB/digital modulation IC) and IC.
There is a high possibility of digital tuner (LNB/Digital Modulation IC) defect, or communication
failure between ICs.
3 Communication error between digital tuner (OFDM/digital modulation IC) and IC,
Digital Tuner (LNB/Digital Tuner Modulation IC) and IC.
There is a high possibility of Digital Tuner (OFDM/Digital Modulation IC) defect,
Digital Tuner (LNB/Digital Modulation IC) defect, or a communication failure between ICs.
Other Try to run self diagnosis again.
