Sony Bravia KD-55XF8796 cyan (blue) LED light remains on and TV dead

[StuartS]

After setting TV to accept wifi using home router and watching you tube - after switch off and next day attempted switch on - cyan (blue) LED light came on (not flashing) . TV is dead and unresponsive.  Repeated forced factory reset attempts without success. Sony troubleshooting indicates that Cyan light should represent screen mirroring ? TV still dead - with no other solution in Sony troubleshooting - help

@stuarts It might be on the demo mode or something, have you tried forced factory reset? take a look here: https://www.sony.co.uk/electronics/support/articles/00274122?link-header

Thank you for the response - unfortunately the forced Factory reset
suggestion does not create a response in the TV. It is still dead with a
cyan (blue) LED light on. We have tried this a number of times without
success. Also we have tried to change the remote controller from activating
the TV by wifi to infra-red also without success. We are assuming that
there is a failure of a component within the TV, and will seek to find a
Sony TV repair person within the local area.

@stuarts If there are any connected devices to the TV disconnect all of them. If the issue remains, you can use this link to locate the nearest service centre to you and arrange inspection for the TV: https://locator.sony/en_GB/servicecenters/?zoom=5&latitude=54.29088&longitude=-2.37305
