Status: offline 		Sorry to hear about the problem. It looks like the FET's (motor controller) overheated and melted. This is typically caused by excessive long term load or a bind; it's extrememly rare to have this happen under normal conditions.

While it's no consolation, the new 7955's have an overload protection circuit that would prevent such a failure. You do need the new HFP-20 programmer to activate this feature though.

Send it the servo and we will most likely replace it under warranty.

Sorry again.

Mike.
