Symptoms
- Record spins but no sound plays
- Sound is extremely quiet even at full volume
- Only faint crackling with no music
- One channel/speaker is silent
Likely causes
- CommonMissing or bypassed phono preampTurntables output a very weak signal that needs a phono preamp (built-in or external) to be audible through regular speakers.
- CommonReceiver or speaker input set to 'line' instead of 'phono'Using the wrong input type causes a very quiet or distorted signal.
- PossibleWorn or dirty stylus/cartridgeA damaged or dirty needle can barely track the grooves, producing weak or no sound.
- PossibleLoose RCA cable or ground wire connectionTurntables have a separate ground wire that, if disconnected, can cause hum or silence.
- Less commonDamaged cartridge or tonearm wiringInternal wire damage in the tonearm can cut off the audio signal entirely.
What to do
- Confirm whether your turntable has a built-in preamp (often a switch labeled 'phono/line') and set it to match your speaker or receiver input.
- If plugging into a receiver, make sure you're using a dedicated 'phono' input, or add an external phono preamp if there isn't one.
- Check that the RCA cables are fully seated at both the turntable and receiver/speakers.
- Make sure the turntable's ground wire is connected to the ground terminal on the receiver or preamp to avoid hum.
- Inspect the stylus for visible dust, damage, or wear, and clean it gently with a soft stylus brush.
- Try a different record to rule out a specific worn or damaged record.
- Test with headphones or a different amplifier/speaker to isolate whether the issue is the turntable or the playback system.

When to call a pro
If sound stays absent or extremely weak after confirming preamp settings and a clean stylus, a technician can check the cartridge and tonearm wiring.
