Toto Soft Close Repair? | Terry Love Plumbing Advice & Remodel DIY & Professional Forum

One of my soft close seats has stopped functioning correctly after maybe... 2 years of use. It sounds like something within the hinge broke and it drops almost as fast as if it were a regular hinge. Are these repairable or do they need to be replaced? I tried searching online and only found other seat failures with no resolution. 2 years is way too short a lifespan IMO.
