Check 10: Is the audio circuit OK?
<Outline> The serial 3 lines digital DACCLK, output from DVD-LSI (IC1501), are converted to analog audio
signal at Audio-DAC (IC1801) and are output from the HOST I/F (CN1901).
Simultaneously, the analog MUTE signal is also output from DVD-LSI (IC1501) via the HOST I/F.
The digital audio signal (IECOUT), output from DVD-LSI (IC1501).
<Check method> Playback DVD-REF-A1 TITLE 2 CHAPTER 1 (48 k/16 bit 1 kHz 0 dB),
and check with DGND being the reference.
In case of NG, check the applicable line, periphery of major components as described in the above drawing,
soldering of the peripheral components and defective components.
NO.
