As in yours doesn't function anymore? I remember seeing a YLOD-victim PS3 getting somewhat revived in Diffato years ago, which had a 50-50 success/fail iirc just to make it work on 1080p. While trying to revive it, I remember that unit being able to run with 480p to begin with though. In any case, it was 'ok' anyway (even with YLOD) as long as it didn't display 1080 nor 720, so you can prolly backup your data before finally moving on. You can try and contact him (if you know him, since RR goes there anyway). I can't remember if he stopped fixing YLODs though. I'm having a blurry memory of him saying something about YLOD'd PS3s being a PITA, or anything between those lines.
If course, that's just one case of YLOD, or probably just a premature version.
