My parents have a 60" XBR2. Hasn't been great with reliability. Two fans, one lamp driver replaced a few thousand hours in (lamp replaced under warranty too), and of course one Optical Block.

For those of you not aware, a civil suit was presented against Sony on the XBR2 also, just like the XBR1 fiasco. Only with the XBR2's, the OB's fail later than in the XBR1. They ended up extending the warranty on all of them to Jun 2010 I believe. Many have been through multiple OB's, seems they're just installing reman'd units.

mD, your XBR2 should've come with a replacement lamp.
