A real display failure with any amount of traffic is a total goat rope.
Approach controllers don't do nonradar and if forced to do so on

Centers these days don't do real well at non-radar, either, compared to the
"good old days." This is particularly so where they provide non-radar
terminal services, such as at a place like Jackson Hole, Wyoming.
