Step 2: Inspecting the Circuit Board
Once the plastic shell is split open, gently move out the internal printed circuit board (PCB). Utilize a magnifying glass or a smartphone electronic camera focused to examine the board. Try to find:
- Micro-fractures in the solder joints, especially around the IC chip and the internal battery holder.
- Loose elements that wobble when gently nudged.
Action 3: Resoldering Faulty Connections
- Warm up a fine-tip soldering iron.
- Use a tiny amount of fresh electronic solder flux to the suspect joints.
