Hi! I have a Bell & Howell Director Series Filmosonic super 8 camera. When I bought it it was broken but I sent it to a place to have it fixed and it was working just fine. The other day I was filming at an event and everything was working just fine until I got about halfway through the cartridge. Suddenly it just wouldn't run. I could still see the light when I pressed the test button, but other than that it wouldn't work. I thought it might have just overheated or something, so I took out the batteries, let it sit for a while, and tried it again. Still nothing. I haven't had the opportunity to test it with new batteries yet (It takes six AAs, they were all brand new when I put them in before I started filming), so I don't know if that's the problem.
Here's a picture of the camera, just for reference
