11. Trouble Shooting Before starting Trouble Shooting O Trouble diagnosing and repairing of set mean find out which PCBs or blocks are not working and replace them with new PCBs. Repairing the broken PCBs are not necessary. Keep the broken PCBs and return them to service center or R&D center. O This Trouble Shooting list only contains representative and simple PCB trouble diagnosis and Module Exchange method. Therefore, if you find sets that are difficult to diagnose or to repair, contact R&D center.
Trouble Shooting Caution 1 !! When disconnecting / connecting connectors, you MUST turn “OFF” the AC power and check the direction and position of the connectors before working. O Caution 2 !! Whenever you reassemble connectors connecting High Voltage Board and POWER PCB (CN805, CN806), 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 is off.
