Back in the day, most analog TV's and audio equipment I would find on the curb could be brought back to life, at least for awhile, by going in and changing out the soldered in fuse. Obviously sometimes the fuse blew because of internal problems, but often was caused only by AC surges from the outside. But yes, many times the transformer was blown and went back to the curb, labelled with the problems I found for the next curb shopper.
