Hi
I have a KD-55X8505B, and am currently trying to control it over IP. A guy called Dave Arnold, who is behind Touch Control is helping me, as my JavaScript is very minimal. I found online quite a lot on this subject and can send you a few helpful links, all the commands are available, but getting these TV's to accept them is when the fun starts. There are headers to send as well as the data, and you have to " Pair" the TV to you controller/software. I currently have got as far as adding my paired device to the TV, but have not got it to accept any commands as yet, but I think it is just my poor scripting. I am using Simple REST Client in google chrome to send the commands to it for testing purposes and I have managed to create a button in Touch Control that pairs it. I'm on my iPad at moment if you want me to send you the info I have, let me know and I'll fire up the laptop so I can copy paste it all.
Chris.
