Hi Arthur,

Thanks for the update.

I have since called support and discovered that after completing a firmware update and a number of resets and power cycle downs etc it turned out that the issue was the HDMI board had gone (for whatever reason).

So to anyone else that has had this issue without resets fixing the issue then contact support and they arranged an engineer to come and fix.

TV now works perfectly well, and the support and getting the repair arranged was very good.

Cheers

Ed
