To support
This morning, I hear a bee sound and saw the LED was off on power supply, and observe the selection switch can't functionand no light on.
When I try to remove the power jag from SB-TB4K, the power supply's LED resume to ON and bee sound has off.
I using meter to check power supply output, it's mesured 24.03v look normal.
I remove all connection on the SB-TB4K and plug back the power, issue come back again.
What was the poblem and sulotion share?
