Hi joesox,

Nomad_6R has shared some hardware troubleshooting tips that can be useful if your servo appears to be burnt or unresponsive. Here's a quick summary of the advice and a few additional tips:

• Smell Check: If you notice a burnt odor, it might indicate that the servo has failed.
• Cable Connection: Double-check that all cables are correctly connected.
• Open the Chest: As mentioned, there are four screws on the back side that secure the cover (or "chest"). Removing these may allow you to inspect the internal wiring and connections.
• Testing Ports: Swap the servo by connecting it to another EZ-B servo port that you know works properly. This will help confirm if the issue is with the servo or the original port.
