Hp LJ III service 50 code

Hello
I received a 50 service code on my hp lj III, i replaced the fuser, and still i got the code. everything i have read points to the AC power module, but i get voltage to the dc power supply, plus there is the +24 volts at the test pin (the connector next to the test button). I need to know if i am supposed to get 120 volts at the connectors that come off the ac power module, that connects to the fuser.

thanks
Guy
There is supposed to be 120V present coming out of the ac power module. It's a switched voltage, so it isn't always present, but pulses on and off to maintain temperature. The DC power supply has nothing to do with 50 errors.
