Step 11

Do not touch ANY part of the logic board previously covered by the black film until the capacitor has been completely discharged. This camera has a 330V, 100 µF capacitor which can cause painful electric shock.
Using the spudger (or any non-metal prying tool), gently remove the black film.

NEVER touch both both capacitor terminals with just one of the wires. This will create a potentially dangerous large spark. This will also cause serious damage to the camera.
Keep the wires connected to the capacitor terminals for 2 minutes to completely discharge the capacitor.
The camera should be completely safe to handle now.
