No sound (during the reception of TV(DIGITAL) broadcasting) (1)
Does not the sound go out though the picture has come out when DTV is received?
Is DTV_I2S signal output from pin (F4/DTV_SCK), (F5/DTV_WS)
and (F3/DTV_SDO) of IC8101 (DIGITAL AV DECODER & MAIN
CPU & VIDEO PROCESSER)?
NO Check IC8101 and its peripheral circuits.
YES
Is DIG_I2S signal input to pin (82/DTV_SCK), (83/DTV_WS) and
(84/DTV_SDO) of IC1302 (DSP)?
NO Check the line between IC8101 and IC1302.
YES
Refer to “No sound output in all modes”.
No sound (during the reception of TV(DIGITAL) broadcasting) (2)
Does not the sound go out though the picture has come out when DTV(H.264) is received?
Is H.264_I2S signal output from pin (D26/H.264_I2S_MCLK),
(E24/H.264_I2S_SCLK), (E26/H.264_I2S_LRCLK) and (A25/
H.264_I2S_DATA) of IC5001 (H.264_DECODER)?
NO Check IC5001 and its peripheral circuits.
YES
Is H.264_I2S signal input to pin (13/H.264_I2S_MCLK), (3/
H.264_I2S_SCLK), (6/H.264_I2S_LRCLK) and (10/
H.264_I2S_DATA) of IC1306 (SW.)?
NO Check the line between IC5001 and IC1306.
YES
Is DIG_I2S signal input to pin (82/DTV_SCK), (83/DTV_WS)
and (84/DTV_SDO) of IC1302 (DSP)?
NO Check the line between IC1306 and IC1302.
YES
Refer to “No sound output in all modes”.
No sound from external input devices (1)
Does not the sound of the audio signal input to EXT1/EXT2 go out?
Is there a audio input signal in pins (6/IN1L) and (2/IN1R) of
EXT1 (SC502)?
NO Check the setting of an external input device that connects with
EXT1.
