Can you please double check the model number of your TV?
I cannot find any info on the model number - KDL32NX503U
Sony link to this model:
As I said, I have easily connected my TV to the internet - this didn't require the TV's IP address - and can stream content without difficulty. However when trying to send from my PC to TV using the Sony plugin on my PC (see below) I get a 'Content Error' message on my TV screen. It's clearly receiving something because the TV picture goes off. It's step 3 of the setup below I can't get to, It doesn't show 'internet video/device information' when I press the 'settings' button.
