When the plastic shell is split open, carefully move out the internal printed circuit board (PCB). Use a magnifying glass or a mobile phone cam focused to examine the board. Search for:
Micro-fractures in the solder joints, especially around the IC chip and the internal battery holder.Loose elements that wobble when gently pushed.Step 3: Resoldering Faulty ConnectionsHeat up a fine-tip soldering iron.Apply a small amount of fresh electronic solder flux to the suspect joints.Thoroughly reflow the solder on the weak connections.
