Test D: Poor Quality/Distorted/No Sound From One Or More Speakers (Not All Speakers) - THX(R)

PINPOINT TEST D: POOR QUALITY/DISTORTED/NO SOUND FROM ONE OR MORE SPEAKERS (NOT ALL SPEAKERS) - THX(R)

Normal Operation
The audio control module (ACM) directs the audio signals to the audio digital signal processing (DSP) module, which processes the audio signals and sends them to the speakers. Each speaker has a signal and return circuit.

NOTE: The rear tweeters are wired in series with each other. A concern in circuits RME30 (VT/BN), VME30 (GN/BN) or VME47 (BN/VT), or a concern in either speaker, may cause poor/distorted/no sound in both speakers.







This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Speaker
- Subwoofer
- DSP module
- ACM
