Shaft Encoder Replacement
There are two possible replacement parts for a broken shaft encoder: a simple shaft
encoder (X50SPR-SE) that must be soldered to the front circuit board, or a complete circuit
board unit (X50SPR-DISP).
To replace a complete circuit board unit because of a broken shaft encoder, see LCD or
OLED Display Replacement on page 110. To replace a broken shaft encoder separately,
follow these steps:
1 Disconnect both power cords and remove the cover as described on page 106.
1 Remove the four electrical connectors located behind the circuit board.

2 Remove the six circuit board mounting screws ( Figure C-14 ).

memory board conductors on the left side.
