One "critical success factor" in repairing IT gear is to focus in on a somewhat limited range of devices. This is one of the things that allows the Apple volunteers to crank out volumes of Macs. If they were trying to repair a broad swath of brands and models, it would be much harder to collect a set of machines with interchangeable parts, and we'd end up with a huge pile of semi-fixed computers.

So! Let's take that approach to another body of IT technology, and that's Dell LCD displays. Some of these models have fallen subject to model-specific component failures. Replace those commonly bad items, and you get a good LCD with minimal effort. (And kept that LCD out of the trash.)
