This is a fault observation. The blue disc has a dark crack running across its face. The photograph does not show what caused it, whether the board still works, or what might replace the part, so the sheet records none of those.
Callouts
- A dark crack runs across the face of the blue disc.
- Two red wires rise from the board on either side of it.
- White adhesive holds nearby parts in place.
- A large black cylindrical capacitor sits in the foreground.
- A grey cable loops around the board.
