Yep, I have, and have the codes. Same exact codes as every other Sony from the past decade or so:

Sony12, Device 1, OBC 46 ON, 47 OFF

Codes for KD-49X83909C, which uses the same Sony remote, hence the same codes:

Your "B" is a 2014 versus my "C" which is a 2015. Same TV, same codes, very minor design changes.

Login required to download from above link. Use Remote Master to read file and IR Scrutinizer to convert codes to whatever format your universal remote needs.

Since you've already tried these codes, something must have gone wrong in your programming procedure.
