1. Test and confirm that the board under test is in the off state, and the electrolytic capacitors on the mainboard have been fully discharged. It is strictly forbidden to test when the mainboard is powered on.

2. Confirm the optocoupler PIN1 (the pin with a small dot on the test board also has a corresponding mark 1 pin)

If the light in the optocoupler test board keeps flashing, it means that the optocoupler is good (the brightness of the light may be different from that of the optocoupler). As long as it flashes, it means the optocoupler is good)
