I would call futuba and ask how much it cost to repair it. It might be cheaper that route than buying new one.

I have ran into same problem on a couple other Futaba
servos. Never did figure out how to get access to wire side of board. I ended up sending them in to hobby services.


Stupid people have no idea how stupid they are!!!

Dunno about the 9256, but I disassembled a really dead S9202 one time. Needless to say, it wasn't going back together ever again.

Futaba tends to glue to motor housing to the case. That means that even if you do manage to pull the circuit board, you end up pulling the motor apart. Even though it might be possible to get it back together, I couldn't figure out how to keep the brushes spread enough to get the motor end back on without buggering up the brushes in the process. On the other side, the POT is held to the case by two plastic "fingers". With the gears removed, you can reach these plastic grips through the two openings near where the POT end is sticking out. Even with the POT loosened, I still couldn't figure out how you could ever get the motor situation resolved unless you de-solder the motor from the board as you remove the board.

Best to send it in for service. Otherwise you'll just wreak it.
