Many of the current crop of TV's can have the firmware updated directly from the device within the settings option and may even prompt you when there is a new one available. However if its not updating, you want to do it manually or have an older TV, below are some resources and pointers which should be helpful and will ensure you update the product correctly.
Its worth noting that updating the firmware *if* done incorrectly can cause issues with the TV, so whilst updating is a worthwhile exercise as updates improve performance and fix bugs, please follow the instructions listed on your products support page carefully when carrying out the process.
- Find your product here - http://www.sony.co.uk/support/en
- Checkout the video here http://www.youtube.com/watch?feature=player_detailpage&v=x62nkI6lzvo#t=136s Note that this video refers to an update from earlier in the year and so whilst exact file sizes may be different (check against the currently available firmware from your products page), the actual process for updating devices is the same.
Do post below if you have any further questions and someone will be able to assist.
