Hello! I’ve had my Polaroid for a couple years now. Every once in a while, a photo that I took would come out completely black. The longer I’ve had it, the more frequent this issue becomes. It’s gotten to the point where I only get one picture out of ever 10-15 I try to take. The rest of them are all black. The flash is working, I’ve tried out all the settings , I’ve taken far away and close up pictures, I’ve changed film packs … any other suggestions ?
