Yellow Light of Death Repair
It took some doing, but this fix seems to have worked. Granted, I've only just turned the system back on and started an update, but that's a heck of a lot better than the yellow light I was getting before. I used the kit, and while peeling off the plastic-y paper backing from the thermal pads was a nuisance, everything I needed was included, and I didn't have any trouble following the instructions in this guide through to get the ol' PS3 up and running again. Thanks, ifixit!
