| But if the repair moves that torch resistor away, like mounted to the side frame with a couple feet of wire, it can't burn up the board anymore.
It has always been possible to repair boards at component level, but today the expertise is about gone except for the engineers and technicians who made the first one work. As a rule in consumer products, the cost for one hour (with overhead) for a good technician is more than the new price of the board (assembled way off shore). Trouble is that has put the good technician out of work so he's flipping burgers.
I have done that to $1000 telephone exchange boards, but the vendor wouldn't trust the repaired boards, even if they did work. Your board has more damage to the board locally, but there may not be any other component failures, and the it could be that every IC has been fried from the wires crossed by the charred board. Repairs go much better when there's a correct schematic and a description of what each connection to the board is supposed to do.
