CED VideoDisc and Player Discussion

Musicality · Joined: 07 Dec 2011 Posts: 4

Well i just got my sgt-100 videodisc player from an ebay auction i won. I tried loading a disc into it, but it seemed to be stopped by something in the way inside the machine. Upon further investigation a large cylindrical object is in the way? it goes from the top to the bottom. I'm not sure what this is, or why is it there, if it is supposed to move or not. but definitely the cause for the disc not going in the whole way. I applied pressure and nothing, the videos i've seen show the disc sliding in with ease, but I have applied pressure and still nothing. Any help would be greatly appreciated.

Right thing to do, and did you take the cover off yet. That will give you the best view. It comes off with 3 phillips screws on the back and 8 hex head screws on the bottom around the sides and front.

Then sit the player back upright and lift the lid off carefully. It will come off. Then you can put the player into load position without it being plugged in and see exactly what is blocking the caddy, and get a photo or several photos of it.

Well, if you're unsure about removing the cover and/or you cannot get a photo of it, you may find the problem and solution here:

Look under the topic = Broken Pivot On Left Receiver Pad Assembly

It still will require a removal of the cover to repair. This will help you to see if this is the problem.

I suspect the cylindrical object is the center spindle, and it will normally drop out of the way when you place the lever into load position. If not, then your problem might be a misaligned load lever or cam.

These are pictures of my player,
The first is looking into the slit that you load the caddies into, the grey thing in the middle is the cyndrilical object that i suspect is the culprit, i can see the caddy hitting it as i insert it.
The second is the top of my player with the big circle as the aformentioned culprit.
The third is showing that the player is registering the caddy is in, but that's all the farther it'll go.
The fourth is underneath the caddy as it in inserted into the player.

For some reason the images are not working for me. Here is a link you can click and see the pictures really quickly:

I haven't worked on enough of these players to know what the problem is though.

That white cylindrical object definitley looks like something that shouldn't be there. In fact, I don't recognize it as a part from the player, but the picture's a little unclear.

Maybe BlindFury can recognize it with as many players he's had apart. Send him an email using his email button.

The only way to really tell what it is clearly is to unloosen the circuit panel board on top, and swing it out of the way in order to get a good look at what's underneath. But I'm pretty sure it's safe to say that object is in a spot where it doesn't belong, if it even belongs to the player.

Since it's an ebay purchase, maybe you can get your money back?

Didn't the picture through the slot look like the turntable not in place? If it isn't that, i'd have to go with Rick on that it doesn't belong. The pic from the top looks like the disc caddy is hitting the edge of the turntable as well. By the way, WELCOME TO CED MAGIC!!!!

Is the big circle object, the one shown in the top view, the turntable? If so how does it work? sorry for my ignorance, i've never seen a videodisc player before this. Also the big circle object is what the caddy is hitting on it's way in. I'll attempt to move the circuit board and post more pictures for clarification.

The turntable is the gray circular part that's nearly 12" across with the spindle in the center.

When removing the circuit panel, make sure the player is unplugged!

Then you remove the small hex screws that hold it in place on both the right and the left. Leave the wires alone, except you might have to loosen a wire tie-down.

Then you can easily tilt the board left side upward and over to the right 180 degrees, leaving the right side where the wiring connects in basically the same spot. You will need to place a coffee mug with napkin on top or such to the right of the player to rest the now upside down board upon.

Then you can takle photos of the underneath and try to make sure you have plenty of light.

edit*** uh oh I think I can see your problem and this Is what I think it is.

In this picture here http://www.flickr.com/photos/72071231@N06/6508194403/in/photostream/
What I did not notice before is that what you see is the bottom part of the turntable. Its what the belt grips to, to spin the turntable and on the reverse is where the magnetic strip is for the drive poles to help spin the turntable. So what you are seeing in that pic is the turntable belt and the lower part/lip if the turntable.

In this pic http://www.flickr.com/photos/72071231@N06/6508193291/in/photostream/
I can see the disc hitting the lower part of turntable and not above the top lip/platter of the turntable how it should be.

Now this is the pic that sold it for me, I just didn't notice it the first look I had. http://www.flickr.com/photos/72071231@N06/6508187831/in/photostream/
If you look at the load/function lever, it is all the way down and so should your turntable. It looks like your turntable is stuck in the off position and your turntable wont lower. Here is a test, When you move the on off load/function lever does your turntable move at all? Does the player power on and off?

Now I cant be sure unless I saw video or had the player in my hands even then I still don't know if this is your problem, but I think something is wrong with your

1. turntable lift slider cam located underneath the player
2. something is broke or loose on your load/function lever
3. misaligned function lever cams http://www.cedmagic.com/tech-info/repair-solutions.html#misaligned-function-lever-cams

Could be none, one, or all 3 of those problems. Hope this helps a little! Good luck, check it out and come back and let us know if it helped or if we can help more!

Good catch on that last photo. You're right, the turntable is up as if in off position and the lever is in load position.

That white part is something under the turntable that has broken and is blocking the turntable from lowering, or needs to be in the proper place for the turntable to lower.

My opinion is send this player back for refund if you are not comfortable with going further on the repair. Unless you paid so little for it that return shipping costs would be silly to pay, or you want to keep it as a project to learn on, or you can get a partial refund without shipping it back.

Now that I think about it further, I realize that the lift lever device that raises and lowers the turntable does have a whitish-colored part to it that is resposible to hold the turntable while lifted into place for OFF postition.

I'm willing to bet that is the part that we see at an odd angle. It should not be at an angle and should not be that visible. Sounds to me like a player that suffered a nasty fall. Send it back and get your money, and move on to getting a good player, I'd say.

It's one of the four photos he posted. I think it's the second one.

Turns out the try that the disc is inserted into was just a little physically stuck, probably from shipping. I messed with it and walked away then heard a thunk...problem solved i guess. Thanks for all of your support and sorry for the long gap in response.

Great to read these posts. My SGT101 had a problem with a cam gear when I got it. I was a greenhorn to the CED format and didn't know what I was doing. With hours of research from the CED Magic page and just tinkering with the machine for hours on end, after a couple of weeks I got it working properly again. John over at CEDatum helped me out with a few questions I had as well. I wish I would have joined this site right away as it would have been done it no time. But it was good experience and I really know a lot about these machines now. How to adjust platter height, adjust the cam gears, platter removal, how to lubricate the turntable, change the belts, how the stylus arm works, and lots more. Glad to hear this was a sucess story and Welcome to the Group!
