If you’re interested, RIP Felix did a pretty good video on YouTube about the YLOD failures. TL:DW is most early models have defective GPUs, plus the ones that survived now have aging capacitors, but there’s tools now to find the exact cause from the system controller (SYSCON). A GPU swap is pretty involved though, so needs a skilled technician to pull it off. Still, if you have one of those early backwards compatible models, having it repaired isn’t that bad of an idea nowadays since those consoles are only getting rarer.
