If you need to ask future questions, I suggest you put something meaningfull in the the Subject. Maybe "Sony TV 16:9 switch" would have been good this time.
If you need to ask a follow up here and/or any future questions, always post the setup code that works basic functions when you ask for info on advanced functions (for a UEI or RS remote such as the 2116). For example, your Sony TV *might* use setup code TV/0000.
Meanwhile, you can find general info on Sony TV commands at
[Link: anycities.com]including the 16:9 command and a related discussion of which models it won't work on (which I didn't really follow since I own neither a Sony TV nor a TV with 16:9 mode).
