Yes there is foam that deteriorates around the prism. It isn't necessary to replace this foam. But that stuff makes one heck of a mess of the prism. The task of getting to the prism isn't that hard, the tricky part is getting all that foam out of there which I used a small flat head, a q-tip, small paint brush, toothpick, and acetone. You'll want to do your best to remove it without getting it on the focusing screen and try not to get anymore on the prism itself. But acetone will take it off the prism... The focusing screen can be trickier as it is very sensitive. Once you clean all that foam out put the prism back BEING CAREFUL NOT TO OVER TIGHTEN THE SCREWS! that will chip your prism. Also use a soft paint brush to wipe the dust from the focusing screen and make sure you wipe all finger prints from the prism. If you don't do all of this thoroughly you will just hate yourself later lol Pictures to follow.<div></div>

I've been working on a Pentax K1000 for a while, the internals are all standard but I've added the improved pieces that were used as the manufacturing continued. Anyway I all of a sudden had issues with the film advance lever jamming and the mirror not coming down etc... After I'd already corrected all the issues this camera had internally. So it was frustrating to say the least. But I eventually came to the conclusion that the arm that shows you advanced the film was the culprit. I take it all apart and find it is bent and chewed up, and so forth. Interesting that this little piece that's just a convenience was the cause of all these problems!<div></div>

It's not the lens I'm sure of that, it's either the viewfinder or focusing screen which I'd only describe the yellowing as looking like glass in a heavy smokers house. However they are not smokers and never have been. His dad bought it in the 80's so it's got sentimental value. He's been using it for years like that with no problems but when I look through it I'm amazed he can even get his pictures in focus. I imagine that it wouldn't be too difficult to fix but as I don't have the camera in hand I can't really get a look at it

My cousin is into photography as well and has a Minolta maxxum HT si I noticed it's very yellow through the viewfinder. This camera was bought new by his dad in the 80's. Is this the focusing screen being stained? And can it be fixed?

I'm fairly confident I can fix it myself I would just like to know if there is any idea of what the problem is, it definitely makes things easier. I've repaired other cameras but not an x-700 as of yet. The others I have repaired are all mechanical so this is sort of the next level

I have 2 x-700 cameras which I bought separately. The first one was unused and works beautifully with nothing needed. The 2nd which i bought for the lenses that came with it, is having some issues which I'd like to see about fixing. I replaced the light seals and mirror cushion (that is a pain in the butt let me tell you) but going back to when I first got it I put a battery in it and it wouldn't turn on. I took the battery back out placed it back in changing nothing and it turned on just fine. Had the same problem today but think it is an isue with the battery cover as I switch it with one frim my x-370 and it works fine. Next question is to do with the on off switch, it's not as "crisp" as my first one and when you set it to the setting which beeps it doesn't beep unless you point the camera at a downward angle. Would this be caused by a wire which came off? Or what would cause this? I'd like to find out before I start taking things apart.

Continued... you can see a bit of the foam on the screen which is the culprit.<div></div>

It would seem the parts camera I purchased has the same problem, as I mentioned before easy fix. Here's some image showing through the viewfinder, the foam on the prism and the focusing screen. DON'T SCRATCH THAT SCREEN<div></div>

A single. I suppose that could be the problem but just assumed it was the camera when one flash that worked even if it had issues stopped working when no settings changed. The camera is currently disassembled and being completely overhauled I have not spotted any issues internally so it may very well be due to the flashes.

Gemini 4700, Vivitar auto thyristor 225, auto flash DX- 700, and I'm not sure what my dad's is

The hot shoe is not firing the flash at all now...
