Re: mosfet mdf13n50

Check and compare the data sheets, a quick look says the 13nm60n handles a couple amps less current but otherwise should work. You should also check the gate drive circuit, resistors etc. and it is also possible the drive ic's output could be damaged, post pictures or at least model of tv, power supply board number etc.
Usually if the fets are shorted there could be source resistors (if used) open also
They should work to test the power supply but its best to use the same or better fets for best operation
