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.

check missing preamp-to-power links in an integrated setup. Exact C 3050 is intended to operate as an integrated amplifier with its own source and volume controls. An external processor/preamplifier is not intentionally inserted. All units are off before inspecting or changing signal connections.
Read the guide →Manufacturer-documented
enable TV power linking with the dedicated HDMI hold. Exact C 3050 is already correctly connected to a CEC-capable TV over eARC. The owner wants linked TV/amplifier power, accepts that behaviour and knows the current CEC Power state is disabled.

explain an inactive BluOS/MDC control without its module. Exact C 3050, not the LE or another NAD amplifier, and the installed option configuration is known externally. Do not remove a cover or install hardware as part of this check.

pair a phone using the C 3050’s own Bluetooth route. Exact C 3050, its supplied Bluetooth antenna already fitted, and an intended phone/computer are available. This is not the C 389/C 399 Sink/Source menu sequence.
Read the guide →Manufacturer-documented
select the already wired A or B speaker pair. Exact C 3050 has a positively identified, correctly wired speaker pair on A or B. No headphone plug is inserted. The owner can lower volume before deliberately enabling speakers.
Read the guide →Manufacturer-documented
check a shifted balance when one channel is quiet. Exact C 389 or C 399, both channels were previously working, the source is a known stereo track, and current balance is visibly shifted. This does not cover a protection warning or damaged speaker.
Read the guide →Manufacturer-documented
Check normal standby after an idle interval. Exact C 389 or C 399 entered standby after about 20 minutes with no user interaction and no active source signal. There is no protection warning, abnormal heat, update or power failure.
Read the guide →Manufacturer-documented
explain a missing chassis Bluetooth Mode with MDC2 installed. Exact C 389 or C 399 and the optional MDC2 BluOS-D module is positively identified from the external configuration or purchase record. Do not remove the cover to identify a module.
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.
