content: The images are too small, only 100x100For what I can tell it's the one on the upper right for the horizontal position of the scope and it's an encoder with pull/push but other than that I can't find a repair manual that has the actual part.

content: Not really it looks like you just resized the low res image so you can't see a thing still, could you take a higher res picture?

content: I would think you have to upload the original image not the thumbnail, Since I'm not there and I don't have any details on how you are taking the pictures and transferring them to your computer and what OS you run I can't help much on the how to do it.

content: If you can see the full resolution image in the computer instead of this low res one, then edit it and resize the image so it's 800 pixels wide while keeping the aspect ratio (reason is because if the image is too big you won't be able to upload it here)You should be able to right click on the image and select edit from the pull down menu.After resizing, Save it and remember where is at.Then under "Attachments and other options", click in Choose files and navigate where the image is, and post.Edit: Whatever you did in this post earlier on shows a full-res image.https://www.eevblog.com/forum/repair/have-a-screen-help/msg507564/#msg507564So do the same thing, maybe resize it to be smaller than 1600x1200. 800x600 will work great.

content: Also I notice that in the other thread you have the full manual, at the end where the schematics are, there should be a part list, that will help.I looked for the manual online with the schematics but I couldn't find it.

content: I looked in parts list and it does not list any switches. In some of the schematics has a few but that is it.The switch has a pot and behind it is a slide switch.

content: Make sure your pot is 10K before you buy it, and use the dimensions to make sure it's a match.Also you might need to modify the shaft because in the blurry picture it seems yours is shorter.
