Kodak Carousel 4400 Slide Projector - Answered Questions & Fixed issues

If the new noise is constant, check the cooling fan for debris of some sort stuck in it. Do not use the projector if the fan is not working as it might overheat and ruin your slides.

The KODAK Carousel 760H was manufactured approximately between 1971 & 1981.
The problem you are describing is most likely a broken cycle solenoid "link". This "link" connects the cycle solenoid and the slide change mechanism. Repair parts are still available, but this is a repair best left to a factory-trained technician. Contact an Authorized Repair Dealer.

Sounds to me like one of the return springs has either stretched out or fallen off. There is no easy way to diagnose this.... takes hands on from an experienced tech. The Slide Lift Lever has to come up high enough to put the slide back into the tray, plus give enough clearance for the tray to rotate. I sure hope this helps. Jim

The continuous cycle condition is caused by out-of-position cycle contacts. See the attached illustration for the correct position of the cycle contacts.

Your problem is most likely related to cycle contact adjustment. See the attached illustration for the parts involved and the SPECIFIC POSITION of the contact parts:

The 140 tray with older slides and an older projector is a gamble with slide jams every time!! Slides have a natural curve that gets bigger over time. In addition, as slides age, the corners will begin to de-laminate (aka: "dog-eared" slide). Because the slide slot in a 140-tray is SO NARROW, the least little deformation of the slide from normal will cause the slides not to drop. My recommendation, given the age of the projector, trays and slides, is to get rid of those 140 trays and stick with 80-slide trays. Good Luck !! Jim

No. The slide tray should rotate when the forward or reverse buttons are pushed. Slides are not required for correct actuation of the tray. Before attempting any adjustment, try a few different trays (it may be a tray issue!). A 140-slide tray will be much tougher to get correct movement from than with a 80-slide tray on an older slide projector.... The 140 tray pushes the interface specification between a tray & a projector to the max.

The cycle solenoid adjust is a pretty straight-forward adjustment. Check out the attached image.

Hardrocko is correct with his analysis. I have attached an image from one of my Service Manuals that may assist you when performing the repair. Good Luck !! Jim

Please let me know what your specific Kodak Slide Projector question is, and I will try to pinpoint an answer for you.

For a model 4000 Carousel, there was no remote. You can lightly depress the "Select" bar by the handle, and that should cycle the projector in Forward. There is no cycling in reverse built into the model 4000, so you must hold down the select button and rotate the tray to the slide number you wish.

You can find FHS bulbs online (Amazon, Ebay or Bulbman are great places to start). If you have a "Batteries+ Bulbs" store in your area, they usually have them in stock. Good Luck !!

If the projected image is getting dim,check the following: 1. 120 volts at the wall outlet. 2. Check that the lamp is completely seated in the lamp house / socket. 3. Cloudy appearance of the inside of the lamp. This indicates there is a air leak in the glass casing around the lamp filament. 4. The lamp socket contacts have a build-up of material on them caused by arcing between the socket contacts and the lamp pins NOTE: Any of these items will also drastically reduce lamp life! Good Luck!! Jim

Try turning your projector on without a slide tray. Cycle it 2 or 3 cycles in reverse. Place the tray back on the projector and cycle forward. By cycling it a few times in reverse, it re-sets the cycling mechanism.

Your projector most likely has a broken Link, which connects the cycle solenoid plunger to the cycle lever. The buzzing you hear is the cycle plunger in the cycle solenoid. This is a quite difficult repair for a trained tech. Parts are available at: www.micro-tools.com I suggest you contact an authortzed repair dealer to make the repairs.

There is usually a sliding tab on the side of the projector (behind the handle) that toggles between "manual" and "automatic" advance. (Some models will have a couple of pre-set advance settings between "manual" and "automatic." These usually advance the slides every three to ten seconds.) Push the tab to the manual setting--this will allow you to use the buttons towards the front of the machine to advance your slides.If moving the tab doesn't work it may be broken or jammed.

1. Does the SELECT button work? If so, hold it & remove the tray (if one is present). Skip to step 3.
2. If the SELECT button doesn't work, remove the slide tray (if one is on the projector) using the emergency tray release in the center hub of the projector. 3. 3. Turn the projector on & try to cycle a few times in reverse. This is how you clear a slide change mechanism jam in the projector.
4. If that didn't work, then either you have a broken cycle circuit wire (usually an orange wire within the projector) or the release wire is trapped under the cycle pad. Refer to the following diagram for the correct "at-rest" position of these 2 contacts. (If you don't feel comfortable doing this, then contact a factory-trained repair dealer).
Good Luck !!

Yes, use a shorter projection lens. You didn't say what focal length your projection lens is, but Kodak and many of their OEM vendors made very short focal length lenses.

Sounds like what your projector needs is a cycle contact adjustment.
Remove the slide tray & lamp module. Unplug the projector. Turn the projector upside down to remove the bottom cover (6 - T-15 TORX screws). Pry the bottom cover off from the handle side (Be careful!! The power cord is physically secured to the bottom cover!). I have attached an illustration for reference. Near the center of the projector you will find a contact as shown in the illustration. That contact needs to be in the position shown on the pad. You will have to slightly bend the "J"-shaped wire carefully(!!). Then plug the projector in, turn it on & cycle it a few times. The 2 contacts should look like the illustration when at rest. If they don't look like that, unplug the projector, "tweak" the contact wire a little bit more, plug the projector in & try again. This adjustment can take a factory-trained repair tech several bends to get it right (without breaking off the wire!!). Repeat until you are successful!

Yes!! The projector is equipped with a "dark shutter", which means light is only allowed to exit the projector when a slide is in the gate. That eliminates the "white screen strain" on your eyes when no slide is present. Happy New Year!
