Code for Using Tivo Remote for Sony Bravia KDL-52XBR4

I have been unable to find the code to program the Tivo Remote Control for the Sony Bravia KDL-52XBR4 LCD TV.

I have even tried using the 0999 code and using the channel up for what seems like 20 minutes but it never turns the TV off.

Does anyone know the 4 digit code for this TV?

Many thanks,

Tim
