Symptom: A bright white horizontal stripe appears across the screen. The width of the stripe is 1/4 of the screen height.
Cure: If stripe is in the upper half of the screen, swap the cables in connectors Y11 and Y13 of the Y- Drive A module. If
the problem is in the lower half of the screen, swap the same connectors on Y-Drive B. If after swapping the cables, the
stripe moves to the new screen position, replace the Ydrive. If the stripe stays in the same position, replace the
corresponding scan module. Don't forget to put the cables back in the original positions.
