Hello, I have a Sankyo em-60xl super 8 camera. I bought this around the end of August and have used it successfully for 4 short projects. about a week ago when I was shooting something for this last project, I turned it off to take a break and when I turned the camera back on, I couldn't see anything through the view finder. There is an open and close switch on the side which I actually haven't touched that in a while, I tried it and nothing happens. When I start it up everything sounds like it's working just fine, I also changed the batteries to make sure it's not just dying on me too, maybe it's just stuck? Does anyone know what's going on and how to fix it and if it matters? It sounds like it's working and I haven't been able to run some film through it to see if anything turned up because I need to use it very soon and can't really wait. I have a backup camera to use just in case, but I like this one better. I'm new to super 8 and I'm still learning about how the cameras work, thank you for any help.
