SC Board Input Signals
Figure 63
Figure 63 is an illustration of the SC-Board connection to the remaining boards of the panel. The SC-board is the interface between the D2-Board, SU and the SD Boards. When troubleshooting, connect a fixed video source to any of the input terminals and observe the input signals at connector SS20 and SS21. See the next two pages for waveform samples.
