Many of the Sony rear projection TVs use a lot of the same codes, so if you can't find a set for your specific TV, try another Sony RP. You can find lots of configuration files for the 60" XBR, for example in the files section here on RC, and I found one that seemed to have just about every conceivable discrete code for my Sony TV.

Alternatively, use the Nevo database to try some other Sony TV remote sets. Personally, I find the Nevo database pretty generic and often lacking the more specific commands I want, so I end up looking elsewhere anyway.
