I removed the AF assembly for cleaning and inspection. The assembly has two lenses. One tied to the lamp the other the photocell. I first removed the photocell for cleaning. Between the photo cell and the AF lens, there is an infrared filter. This thin mylar filter was black. it should pass visible light, so there is the red flag. I put the filter against a fluorescent lamp and not a ray of visible light came through. I decided to put it back together without the filter and wallah! AF works!!! The question is should I source a new filter? At the lamp setting I use, there is not much heat at the negative. I have measure it a t 84 degrees. Also I wonder what made the filter go opaque. I'm thinking this is the reason so many have non op AF systems.

Sounds good I’ll see if I can source a new lamp and remove the AF assembly to inspect closer. I’ll keep you posted.

Hi Joe, I have replaced the C102 and C103 caps in question with these 106BPA050M Illinois Capacitor / CDE | Mouser they are bipolar but not sure about their specs for this application. They were less than $1 each. Yes Manual focus works well. The AF lamp is ever so slightly loose. Seems like the glue is a bit soft and yellowed. It's illuminated so I'm assuming it's still ok. I think I will remove it and clean the old glue off and re install. What type of glue shall I use? The unit arrived extremely clean inside however I have thoughtfully cleaned everything more including the two AF sensors. I'm not sure were the AF lamp lens is though. Maybe I have to remove the lamp to see it? I did locate the variable resistor for the AF sensitivity. I believe it's the P103, there is a regular resistor R103 as well. The P103 is accessible through the bottom cover. I have played with that and am using it now to prevent the lens from being pushed out the front. After I replaced the caps I tried to re adjust it. With all the covers off I put a glass slide in place and adjusted the P103 just untill the lens creep stopped. After that I manually focused the slide then reached in and pushed it a bit forward. This activated the AF motor but it would not stop. When trying to push the slide the other way the AF system would not activate. So it seems like one half of the system is not working. Thanks for your help, it's greatly appreciated!

Thanks!! Here is a copy. https://steveruddyphotography.com/images/Forum_mages/Rollei-P66s_Rep.book.PDF Here is the web page were I found the service manual. Anleitungen | Rollei Diaprojektor Rolleivision

No need to snip the wires. You can either tape the sensors with black electrical tape or do as I did and turn the sensor adjuster. It’s accessible via a hole in the bottom of the projector cover. This is to fine tune the AF, but since mine can’t be fine tuned, I just have it turned to the point of non movement. I have the service manual that explains the circuit but haven’t been able to identify all the components. I’m not used to working with circuit boards so it’s going to take some time to trace the AF circuit. I was hoping to see what others had to do to fix it. I have seen numerous posts saying the lens will not stop during AF and gets pushed out but no one mentions how to fix it. Mine is doing the same. For the heck of it I replaced all the capacitors. I only know how to check resistors and checked several while changing the caps. I’ll check the few remaining and try and trace the circuit.

Yes, hoping someone in 2019 still has the knowledge to help me fix the AF system. I got excited when I saw I had a reply. :-(

I need the solution!!!

I have the same problem. I see this is an old post but hopefully I can get help. The link above is now dead. I have replaced the capacitors on the board but that wasn't the issue.

<p>OK I just watched the video. It looks like your saying that LR's monitor gamut warning feature is accurate. I wonder why they haven't made PS the same? After all I did pick my monitors profile for proofing in PS. Anyway when I did the Grainger Rainbow test in LR it passed all colors except a minuscule amount in the white area. Since you all say this chart is old and not useful I found a different one. What do you all think about these results? It's showing a lot of clipping in the color bar, see link below. I did calibrate my monitor using the monitors native color space which is supposed to be 99% of the Adobe RGB.<br> http://www.coralreefecosystems.com/forum_images/MonitorColorspace.JPG</p> <p> </p>

Thanks Guys, I'll check out your video now Andrew. You didn't mention if the video explains how to test the color space of your monitor. If not how can I do it? Thanks

<p>I just purchased a newly released Eizo CS2730 and wanted to test how much of the adobe RGB 1998 color space it can handle and I'm seeing a lot of clipping. I calibrated the monitor using Color Navigator and picked native gamut during the calibration which is supposed to be 98% of the Adobe RGB color space. Here is a photo of the image in PS with the Adobe RGB colorspace applied and proofed with my monitors profile. Why am I seeing out of gamut warnings?<br /> <img src="http://www.coralreefecosystems.com/forum_images/rainbowGamut.JPG" alt="" width="1510" height="698" /></p> <p>http://www.coralreefecosystems.com/forum_images/rainbowGamut.JPG</p>
