Scope and coverage
Choose your exact model to see current coverage. The library currently contains 2700 guides for 327 exact reviewed models. Other reviewed models remain searchable and receive an honest “no matching guide” result when no procedure applies.
The checks use manufacturer or platform documentation. Separately labelled owner reports help us choose useful checks and explain real-world uncertainties; they do not prove a cause or a cure. These procedures are not our physical tests, even where a linked review is hands-on. If a required menu, version or condition is unknown, follow the unknown branch.
Manufacturer-documented
add Sound Delay only when the audio arrives early. Exact VSX-935 has working HDMI audio that visibly arrives before the picture. If sound already arrives late or the direction is unknown, stop rather than adding more delay.

check Fixed PCM when a non-PCM source is silent. Exact VSX-935, correct known HDMI source selected, source positively confirmed to send a supported non-PCM format, and receiver volume low. This is not a protection fault.

check surround silence caused by a Stereo listening mode. Exact VSX-935 has a correctly installed known surround layout, front speakers work, and the receiver currently shows Stereo. This is not a speaker wiring or calibration procedure.

compare the configured network mode with the actual connection. Exact VSX-935 and the owner’s intended wired or Wi-Fi connection are known. No router security changes, credential submission to Audio Fix or factory reset are required.

pair a phone to the receiver rather than enabling its transmitter. Exact VSX-935 will receive phone/computer Bluetooth music. The intention is not to send receiver audio to wireless headphones. Pause other playback and keep levels low.

respond safely to volume reduction after extended hot operation. The exact VSX-935’s volume falls after prolonged operation and heat is suspected. This guide does not prescribe a higher gain setting or claim every volume drop is thermal.

restore a display turned down by DIMMER. Exact VSX-935 is powered and otherwise operates, but the front display is dim or off. No firmware update or protection warning is active.

Read the guide →Audio Fix follows structured steps with sources attached to each claim. Forum experiences are labelled User-reported and kept separate from the evidence supporting an instruction. Unknown details remain unknown. Finishing the steps is separate from reporting that a problem is solved. A changed or withdrawn guide cannot silently resume an old procedure.
