4. Digital/Tuner/D-AUDIO P.C.B. System Diagnosis
(1) IC communication in the digital P.C.B. (CPU and Flash/DDR/HDMI, etc.)
<Diagnosis Result Value>
(2) IC Communication of TUNER System
<Diagnosis Result Value>
0 No abnormality was detected in the digital P.C.B..
1 If there is a communication failure between CPU and FLASH/DDR, there is a
high possibility of digital P.C.B. circuit (such as foil cutting) or parts failure.
2 If there is a communication failure between CPU and HDMI-LSI, there is a high
possibility of digital P.C.B. circuit (such as foil cutting) or parts failure.
3 There is a communication failure between CPU and FLASH/DDR, and between
CPU and HDMI-LSI.
Take measures for "1" and "2".
4 There is an abnormality in HDMI-CEC circuit operation (High/Low Output).
There is a high possibility of digital P.C.B. circuit failure (such as foil cutting) or
parts failure.
5 There is a communication failure between CPU and FLASH/DDR, abnormality
in HDMI-CEC circuit operation (High/Low Output).
Take measures for "1" and "4".
6 There is a communication failure between CPU and HDMI-LSI, abnormality in
HDMI-CEC circuit operation (High/Low Output).
Take measures for "2" and "4".
7 There is a communication failure between CPU and FLASH/DDR and between
CPU and HDMI-LSI, abnormality in HDMI-CEC circuit operation (High/Low Out-
put).
Take measures for "3" and "4".
Other The Input Code is not correct. Please check the Diagnosis Code again.
0 No abnormality was detected in communication between the Digital Tuner and
IC.
1 A communication abnormality occurred between the Digital Tuner (OFDM/Digi-
tal Modulation IC) and IC.
There is a high possibility of Digital Tuner (OFDM/Digital Modulation IC) defect,
or a communication failure between ICs.
2 A communication abnormality occurred between the Digital Tuner (LNB/Digital
Modulation IC) and IC.
There is a high possibility of Digital Tuner (LNB/Digital Modulation IC) defect, or
a communication failure between ICs.
3 A communication abnormality occurred between the Digital Tuner (OFDM/Digi-
tal 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 The Input Code is not correct. Please check the Diagnosis Code again.
