Check 3 : Is the audio circuit operating normally?
Reproduce DVD-REF-A1 Title 2 Chapter (48k/16-bit 1 kHz/0dB).
Checks are to be conducted using GNDAU1 (sensing pins) as a reference.
If the locations, listed under "verification location 2", can be verified, there is no need to conduct verifications for
the locations listed under "verification location 1."
If the result is not satisfactory, check to see if there are any problems with resin flux cored solder and other
defects in the applicable line, vicinity of major parts stated in the above diagram (Circuit Diagram ) and
peripheral components.
