I used to be local teen that would fix everyones Playstation 3's, when they got the red light of death. I used to do the heat gun trick to get them back up, but decided to also try an oven at one point (it worked). I wonder if this was the same phenomenon...
My understanding is that the ps3 and 360 had similar (but not entirely identical) issues, but the common "repair" on the ps3 was to change some unique (NEC tokin) capacitors around the CPU/GPU... only problem was that, like the hotbox "repair" it would fail again within a month if it worked at all.
