1. Repair Instruction
For repairing this issue, we need to change Main Board after checking resistor value.
1) Measurement and replacement of main board is applied to the use of long-term inventory and to all boards to be
received
from the field in the future
2) If issue is happened, Change from issue Main Board to improved Main Board after checking the resister value because it
has
no Part Number changing.
(Improved Main Board information : The Board that is produced after '19.3.27 / '19.3.29 / '19.4.8)
The Board after '19.3.27 : CJ98, CJ88, CJ87
The Board after '19.3.29 : CJ45, CJ44, CJ65, CK57, CK56, CK43, CK99
