You will need to check what your current software version is on your TV. If you need the newer version download it from your pc/laptop onot a USB memory stick. This USB stick fits into a port on the side of the TV.
You can then start the update. Follow the instructions carefully from the link I gave you. The TV will go off while updating but wait until it comes back on and confirms update successful.

I found after doing the update I had to redo the clock on the TV and retuned the digital channels.
I'm waiting untl tomorrow(after the TV has been switched on standby tonite) to see if the programs have been saved .
I have exactly the same with a SONY Bravia KDL40S5650 since the Digital Switchover on 26th Oct. Have downloaded the latest firmware, but to no avail. Also had 3 year warranty with the TV but SONY seem to be disputing this although t is not 3yr old until late December. Did you have any joy getting your problem resolved? Ta
