Hi all, I have tried 2 different lamps on the moviedeck 455, but to no avail. One was an ELB and the other an ENZ 50 W 30 V. None worked. I noticed that there is no light switch on the projector. Would there be an internal switch that I am missing, or is it simply supposed to turn on when I engage the threading knob? Any help is welcome.

The lamp is lit on the Moviedeck whenever the motor is operating. This puts quite a dsplay on screen if you allow the machine to rewind back through the projection path!
It sounds like you have some kind of power supply problem: hopefully something simple like a dirty contact or a loose connection.
BTW: Are you confident in those lamps?

Yes, both lamps are brand new. That is why I'm so surprised they don't work, because the projector is in excellent condition.

OK,
The odds of two new lamps being duds are pretty small.
Your basic choices are too much lamp voltage (are the filaments of the lamps intact after you tried them in the machine?) or little/none. I'm guessing you will find there is too little.
Note: Try not to touch the lamp's envelope. If you do, swab it with alchol before you light it again.
If you are handy with a voltmeter this is the time to crack 'er open and poke around to see if/where the volts stop.
If you aren't, this is the time to figure out who of your friends is handy with a voltmeter (-anybody who knows every Star Trek episode by title and production date is a good candidate...) and get their help.
