Hmm. If you're positive the screws are tight then this definitely sounds like the “clutch" inside the top lid assembly is worn out and most likely not worth fixing (if user replaceable at all, I forget). It's a decent size job if it is do-able so it may or may not be worth the time and effort. Basically depends on your level of expertise and cost of parts vs age of machine. It might be worth just using as is until you can find another machine. Good luck either way.
