Getting an error on TAF to check opto 55 the third opto in the bookcase and opto 85 the thing "up" opto. During the Thing test the "up" opto is always closed even when it shouldn't be. Also every other switch in this Row is out. It is row 5 on the matrix. There are no visible breaks in their common wire. Could it be an MPU issue? Could a bad opto cause all the other switches in the row to fail?
