I can't get the light to come on.

Sounds like and auto-timer for playing a cassette of slides automatically?

You can do what you describe with Kodak projectors and Kodak trays !! Jim

Try searching at www.bulbman.com or at a "Batteries plus Bulbs" franchise. Look on the lamp for a 3-letter code. This ANSI code is unique to the lamp and is a great aid in lamp identification.

I would recommend Kodak Ektapro 7010, 7020, 9010 or 9020. Great, dependable international machine! Jim

I can't comment on the projector, but I can tell you that paper-mounted slide will warp, due to the affects of temperature and humidity. Warped mounts will mess up the auto-focus in any projector.
Good Luck !! Jim

I have a VIVITAR 5000 AF slide projector.

Occasionally, the slide gets stuck while operating the mechanical hand to change the slide. Most of the time it works when I push the slide carrier by hand. Very very infrequently, the projector actually throws out the slide.
I have ascertained that teh Kodak slides which are mounted on paper frames are much too thin for the mechanical hand pushing teh slide in and out. The solution is to remount teh slides on palstic frames or some how add to the thickness of the slide. I have not tried it yet , though.

Any more ideas?

Check with: www.bulbman.com They have an amazing assortment of lamps for all vintages & brands of projectors!!

First, check to see if the lamp lights at all (spill light coming out of the projector near the fan). If it does, then the problem could be just the "dark shutter" not opening. If the lamp does not light, it could be a couple of things: it could be the lamp thermal fuse has opened or it could be a bad lamp socket.
Sounds like you need to seek out a factory-trained repair dealer for this one, to narrow down the possibilities!

this switch is generic to other models so ask the agent for a spare

My slide has the remote but remote is not working the projector i have is v5000Af
