In just a few cases resistors are specified to act as fuses. Usually in the power supply area. Some are obvious - wirewounds with a soldered contact thatwill melt and spring apart. Others are not, just specially rated parts that will go open circuit peacefully. In modern kit these will be marked on the schematic along with warnings in the service data to replace only with the same type.
Convergence circuits are unlikely to need fusible resistors.
