The best collection of Sony IR commands was put together by Rob Humphries at [Link: hifi-remote.com]

If you got the discrete power commands that were posted in the Discrete section to work, then you know whether it reponds to AV1 and AV2 commands and you can figure out all the rest of the commands. There is a section that explains how to use MakeHex to create pronto hex form the commands listed.

Most of the Sony input commands are pretty common across the board AND if you are using AV1 then there are a lot of ccf files that should have the discrete input commands.
