MCM (Multi Chip Module) In this case, replace the panel. 1 electrode open 1 line open Line open or short This phenomenon is MCM of the Film and rear panel electrode problem. Trouble shooting. MCM can not be replaced separately. So replace the ctrl b/d. This is due to COF IC inside short or adherence part of Ctrl b/d defect. Vertical defect (line) 1 line open or short with same distance. 4.
