If you must replace a capacitor, insert new parts carefully to avoid a short circuit caused by the near 

pin. 

 

Do not get the board wet. Water and moisture can cause a short circuit that causes malfunctions. 

 

To avoid damage, be sure to use lead-free solder. 

 

When soldering, work quickly to avoid overheating the circuit board. 

 

Keep the soldering iron tip clean and well tinned when replacing parts. 

 

After repair, perform a close inspection of the circuit board to confirm it is in good condition. 

 

After repair, perform a function test to confirm the power supply is working properly.
