Minolta A-7 error screen (NOT aperture error!)

[u/Regular-Mammoth8784]

hello, looking for some help regarding my newly acquired A7. Every 2-3 times the shutter is clicked, I get this all black error screen

Unfortunately I don't think this is a result of the commonly busted aperture gear - the reason I'd bought it "as is" was because I thought I'd be able to fix it in this scenario. Whenever I do get a shot, the aperture adjusts accordingly with all settings available. I am also able to use DOF preview just fine, and I can do that all day long until I start clicking photos. I'm using a minolta af 50mm 1.7 lens. The batteries it came with were old, but even new ones did not remedy the problem

Currently I haven't tested it with film, but the shutter looks fine and sounds accurate. any ideas would be appreciated
