I think this happened to me as well. I had something pop my FEP film, and I replaced it, and tried a couple prints, but really didn’t like the whole resin experience, so I sold my printer.

When the buyer got it home, he told me the screen was cracked. We weren’t sure whether it happened in transit or not, and I’d given him a pretty great price on the thing with a washing machine and a ton of resin, so he decided he didn’t want any money back.

After learning more about resin printers since then, I now it this was my fault and I feel bad about it. Either way, I’ve definitely learned to check the major components before buying or selling something.
