Sony Bravia smart TV - internet connection breaks down

[omnavan]

I have a Sony Bravia smart TV connected by ethernet cable to Virgin Hub3.0.  When TV is unplugged I have >200Mbps download and >20Mbps upload speed - excellent broadband.  Once I switch on TV internet connection breaks down

Hello there

The first two steps in the troubleshooting process is:

• Ensure that your TV has the latest firmware installed
• Factory reset the TV

Unfortunately you havent listed your TV model number so I cannot give you instructions on how to do so.  If you need instructions and/or the above fails to fix the problem, please reply back with your TV model number.  Also are you using wireless or a wired connection?

Cheers

Thank you for prompt reply.  TV model is BRAVIA KDL-40W605B.  I am using wired connection.  Previously I was using wifi connection - the same problem.  TV wifi is switched off.
