g SW POWER SUPPLY Primary side electrical shock
The primary side of SW POWER SUPPLY remains voltage long time, and the primary solder side can be seen.
So if you touch the primary solder side, it is possible to receive an electrical shock.
There is the red area below where we tend to receive an electrical shock.
Be sure to discharge the voltage of primary side to avoid receiving the electrical shock.
Electrical shock area of A-side.
Electrical shock area of B-side.
When discharging the above point, use the following discharge jig as needed.
While the charging voltage is left of both C4 and C5, either of checking LEDs turns on.
And if both of LED turns off, we can avoid receiving the electrical shock!!

No
polarity
The circuit of "discharge JIG" is shown below.
! Resister is all 10 k (3W)
! Both of LED is LTL17KRH5D
When there is no above type LED, take measures the following method.
Step 1: After the power is turned off, wait 2 minutes.
Step 2: Connect the Register Jig and leave the unit as it is, for 10 seconds.
