SC Board Isolation Procedure (TC-P42S1)

When the SC board is suspected to be the cause of a 6 or 7 blinks condition, it can be isolated for confirmation.

To isolate the Scan Drive Section (SC, SU, and SD board), remove connectors SC2 (Vsus) and SC20 (P+15V, P+5V, and scan pulses) from the SC board and connector SS33 from the sustain board.

When this is done, the display is completely black (No picture)
