Narrative:

The grand turk ATC B1-5 radar failed for 17 hours on apr/xx/96. This occurrence started with a power spike that shut down channel a but also somehow locked out the remote monitor at ZMA. This outage caused many delays and could have been about 30 mins if the technicians had found the problem at the center. FAA maintenance has implemented procedures to solve this problem in the future.
