Hi, there were three units of which I remember that effect. One of them could be repaired by replacing the interconnection between the upper and lower half with a suitable piece from another unit.
The percentage of units with that effect was small, given the many HP-71B units which went over my desk, but the general problem stays.
Interesting that in all cases it was one of the later units with changed interconnection
