I hope this screenshot image of a photograph taken of the rear cover of a Sony TV, along with the few words of text, will be sufficiant for you to procede.
What additional information were you trying to discover through the use of your email to Sony?
If the only answer to your email was that they want you to go to a service center along with your 230 pound Sony TV, then it appears that they do not want you rooting around inside this TV.
If you purchase an official Sony repair Service manual, I do NOT believe that you will be provided with any instructions that will assist you to mechanically extract the loadspeaker. Most of the document for the XBR800 series is devoted to the electronic circuits and the Service Menu. I imagine that a similar document designed for the XBR400 series will be just as restrictive in providing practical information.
There are some mechanical tasks that electronic technicians are expected to know how to do instinctively. That is why everything is not spelled out in a Sony service manual. People who decide to open up the back of their TV are expected to have a minimum experience in electronic or electric appliance repair. That being said, if you had blown a driver in a hi-fi loadspeaker cabinet, no one would expect you to be a licenced professional in order to do your own repair, perhaps at most a woodworker. Occasionally one has to de-solder a wire, but often there are connectors for the speaker drivers.
Your TV may have a sub-woofer in addition to the two stereo speakers. You may have to consider the possibility that your loadspeaker is not defective but that your internal audio amplifier is burnt out instead. Try swapping loadspeakers in order to determine this.
I leave it to you to decide what to do next.
