Follow these checks in Audio Fix →

When this guide applies

Only listed exact models with one known external RCA plug partly withdrawn at its already confirmed correct jack. Deck already unplugged, amplifier off, protected arm resting, undamaged accessible cable. No cartridge leads, internal wiring, mains action or mini-XLR connection.

Connection scope: Turntable / phono audio. Symptom: Sound plays from only one side.

This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.

If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.

Checks and possible outcomes

Start at scope. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.

scope

Confirm the exact setup

Is one external RCA plug visibly partly withdrawn at its known correct phono-route jack, with the listed turntable already unplugged, amplifier off, protected arm resting and the undamaged cable safely accessible?

Look for: Choose only a detail you can confirm.

Trace the loose plug’s exact channel

Read the actual L/R jack labels and trace the existing cable so its original correct destination is certain. Do not infer from an unfamiliar colour or touch cartridge leads.

Look for: Perform this one check and observe the actual response.

Seat only that loose signal plug

Seat the known loose RCA signal plug fully in its already confirmed matching jack without force. Stop if the cable or jack is damaged or cannot be reached safely.

Look for: Perform this one check and observe the actual response.

Possible result

Confirm the unknown detail before proceeding

Stop rather than infer an installed cartridge, partner, source level, cable capability, software version or control state.

insufficient data

Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.

    Possible result

    Keep the actual observation for support

    Record the exact model, source, connection, control state and response. These checks do not diagnose a failed component or prescribe a reset, update, internal repair or mains change.

    next support

    Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.

      Possible result

      Keep the observed result

      This is the outcome observed in this setup, not a guaranteed cure, Audio Review physical test or measurement.
