Trouble Shooting
- Caution 1 !!
When disconnecting / connecting connectors, you MUST disconnect the AC Power.
And check the direction and position of the connectors before working.
- Caution 2 !!
Whenever you reassemble connectors connecting High Voltage Board and POWER PCB,
remaining voltage still exists in the POWER PCB could cause electric shock and damage
the set.
Therefore always reassemble the connectors several minutes after AC power disconnect.
To be more careful, using a Multimeter you should check to see if Vs is less than 10V
and then connect connectors.
