I just got off the phone with Sony, and of course I'm having to wait 72 hours for someone to call back. The man I talked to assured me I'd be taken care of this time, and that there was a good chance they'd replace my unit with a comparable unit, since they don't make the XBR1s anymore. So it sounds like I'll probably end up with an XBR2.

Still, how is anyone sure that the problems have been addressed with the XBR2s? Discoloration didn't happen for me for at least six months. Or do the XBR2s also serve as crystal balls?
