When this guide applies

Exact Thorens TD 1500. Matching correctly mounted cartridge and counterweight; actual cartridge force and scale units must be confirmed independently. Only normal external user controls; no mains modification, chassis opening, reset or firmware installation.

Connection scope: Turntable / phono audio. Symptom: The record skips or the tonearm will not track.

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

Are exact cartridge force and scale units documented?

The deck is off/stopped and stable, mounted cartridge/weight are confirmed, its actual prescribed force and corresponding scale units are understood and you accept careful normal external adjustment. Never interpret the manual’s mistranslated “pounds” as an actual pounds-force instruction.

Look for: Choose only a detail you can confirm.
