Activating projector how do I activate the slides manually? I dont have a remote for this 4000 model.

According to the manual listed below you can :
(1) Enter the OSD menu.
(2) To execute "Reset" function.
This resets all the user settings to default.

Press "Play" to change the "Administrator Password".
The factory default of "Administrator Password" is "1234".

Ektagraphic III A did not have remote focus. Someone has probably substituted a remote from a higher functioning model on this projector. The forward / reverse functions on the supplied remote will continue to function correctly, but the focus buttons will not.
Good Luck !! Jim

You didn't specify a model. That will change the detail-level solution... The most generic answer I can give you is that the slide advance mechanism is supposed to make one revolution and then be captured until it gets another signal (like from the FWD/REV buttons) to activate. The most likely cause of continuous cycle is that the wire that CAPTURES the slide advance mechanism is either broken off, burned off or out of adjustment. With more detail I can be more specific. Good Luck!! Jim

Given the fact that your projector is at least 45 years old, the #1 problem in projectors of this vintage is brittle plastic parts. There is a plastic link between the cycle solenoid plunger and the cycle lever. This part breaks - - - a lot!! If you replace it, you should be good. You can order the LINK from: www.micro-tools.com

Here's what the User's Manual says:

Using the Remote Control

To advance PowerPoint slides with the projector's remote, you

must connect the USB cable on the projector's computer cable to

the computer. See page 8 for more information.

Point the remote control at the projection screen or at the front or

rear of the projector (not at the computer). The range for optimum

operation is about 30 feet. If you point the remote at the

projection screen, the distance to the screen and back to the projector

must be less than or equal to 30 feet. For best results, point

the remote directly at the projector.

If you are displaying presentations in Microsoft® PowerPoint®,

you can use the remote's Previous and Next buttons to navigate

through your presentation while in Slide Show mode.

I had a similar problem and was able to get the full view by giving the change button a quick touch for a partial activation. It seems as though the cycle does not complete before the motor is turned off at what should be the end of the cycle. I took it apart to find the problem but did not discover the correction. So the little "flick" on the change button finished moving the slide into position and the "blocker panel"(inside the projector)) out of the way so the whole slide could be seen.

You didn't specify the model, but chances are that the cycling problem is caused by a broken "link". The "link" connects the cycle solenoid plunger to the slide change mechanism. The "link" is made of plastic, and gets brittle & cracks over time, rendering slide change non-functional. Parts are still available (www.micro-tools.com), but this is an involved repair requiring disassembly & a service manual - - best left to a factory-trained repair dealer.

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