EN 16 5. LGE PDP 2K6 Service Modes, Error Codes, and Fault Finding Line Open or Short with the Same Distance This is an MCM of Control board defect. The MCM cannot be replaced separately. So replace the Control board. MCM (Multi Chip Module) Disconnected MCM of CTRL board defect. MCM can not be replaced separately. So replace the CTRL board. G_16390_064.eps 180806 Figure 5-15 Evenly repeated lines 5.1.4 Bar Defect (Horizontal) Most horizontal defects can be repaired.
