[6] AUDIO SYSTEM
Flowchart of Failure Analysis for The Audio System
=> AU1 Has the sound been emitted from the speakers? Yes No Is sound muting set? No Is the volume set to 0? No Is a headphone inserted? No Is a SPDIF signal input to IC7602 (DP TX)? (pin 6) No Is a SPDIF signal output from IC5801 (MSP)? (pin 126) No Yes Check around the IC7602 (DP TX) and the communication with the microcomputer, and replace the System Cable. Repair the failure points, then check again. Yes Check the IC5801 (MSP) and peripheral circuit and clock output of X5801. Repair the failure points, then check again. Yes Pull out headphone, then check again. Yes Raise the volume, then check again. Yes Cancel muting, then check again.
