Swapping out the panel is fairly easy in most (all?) Thinkpads and they're pretty cheap to source especially if you don't mind buying used. A bit of Googling on the Thinkpad model number will reveal which manufacturer's panels are good and which are bad (often the same IBM/Lenovo part number is used irrespective of the supplier) for that model. Or sometimes another panel with the same dimensions and spec that matches the gpu/connector can be used (often Dell and Lenovo are using interchangeable panels in similar model ranges, used to be the case with Apple too but nowadays they seem to do exclusive deals with manufacturers and don't let anybody else play). Not a solution that everyone can be bothered with but I've vastly improved some cheap 2nd hand Thinpads with a nice new screen.
