Step 2: Inspecting the Circuit Board
When the plastic shell is split open, gently slide out the internal printed circuit board (PCB). Utilize a magnifying glass or a smart device camera zoomed in to inspect the board. Try to find:
- Micro-fractures in the solder joints, particularly around the IC chip and the internal battery holder.
- Loose elements that wobble when gently nudged.
Step 3: Resoldering Faulty Connections
- Heat up a fine-tip soldering iron.
