Suggestions: Check the Scan pulse waveform at TPSC1 of the SC-Board. (Use TPSS1 of the SS- board to trigger the oscilloscope.) Proceed to check the power sources at connector SS11, SS12 and SS33.

Verify that the clock and serial data lines from the D- board are present at connector SS33.

Note: It is easier to measure input levels at connector C33 of the C3- Board instead of connector SS33.
