HDMI notifications

[Tallis]

I purchased a SONY BRAVIA 8 65" K65XR80PU and SONY BRAVIA THEATRE BAR 8 in early September. On the whole I'm very satisfied however, there is one annoying niggle that I hope you may be able to offer some advice and perhaps a solution.

The Sony Theatre Bar is connected via the specified eARC HDMI port and a Sony Blu-ray Player and also an EE TV Box Pro are connected to the television via HDMI ports 2 and 4 respectively and the Set Up process completed for each.

Although these devices are correctly identified on the appropriate HDMI input and function correctly when turned on I continue to get a 'BRAVIA notifications' that reads –

"Device connected to HDMI 2 (or 4)
Select [Set up] before starting set up on the device"

I have done this numerous times, including after a 'Power Reset', and although the 'notifications' may disappear for a short time they soon reappear.

I have performed a 'Factory data reset', purchased new 'high speed' HDMI cables and also completed the latest software update and although fine for a couple of days the 'notifications' have started again.

I would obviously appreciate any suggestions and a permanent solution to this problem.
