If replacing the battery does not solve the issue, the issue likely lies within the internal electronics. Over years of everyday use, the microswitches (the physical buttons soldered onto the circuit board) can break out from the board due to recurring clicking pressure.

Tools Needed for Internal Repair:

• Precision soldering iron
• Solder wire and flux
• Amplifying glass or jewelry expert's loupe
• Replacement microswitches (if a switch is totally broken)
• Isopropyl alcohol and cotton bud for cleansing
