Yes we had one of those soft toilet seat lids that self close, the problem was it moved. Thought the issue was with the nut and plastic bolt underneath but it wasn’t. Looking on the internet I saw the pins the cover locked into . these pins have a metal plate when removed expose a tightening screw. Could I get that plate off??? what a game that was, it should have just lifted off but either the cork wash underneath had stuck to it or what I don’t know.
In the end had to resort to using 2 screwdrivers either side and jemmy it off. That then reveales the troublesome screw in a elongated slot which was loose. So on back with the toilet seat lid to line up the fixing pin clean out the gum type stuff that stops cap removal and reasembled. Total cost £0.
this video showed me how if you need to do the same
