Narrative:
At approximately XA00 local, aug/xx/97, the radar scope at the seall position in the islip sector at the new york TRACON was reported to be unusable by the controller working the position, due to the radar display 'spasming' and distorting. The airways facilities technicians arrived in the sector promptly, and began running diagnostic checks of the radar scope. The airways facilities technicians found a printed circuit board which had gone bad. They went to their stock room and got a replacement printed circuit board, which they had recently received from the repair contractor, and was still in the sealed container. When they installed this 'new' printed circuit board, they discovered that the original problem with the printed circuit board was still there! Whatever repairs the contractor made did not fix the problem that the new york TRACON airways facilities technicians had originally idented. The airways facilities technicians were forced to cannibalize from another radar scope in order to return this one to operational service.
