Brand new BT Youview box connected ok to Plusnet broadband - Switch all on and 'Waking up' screen opens, stays for about a minute then TV screen goes blue. HDMI1 is correct port and properly set.
No remote controls or box top controls operate except to switch off.
It's a Toshiba TV and worked before with the older BT box until a loose connection required me to replace it. Any ideas?
I suggest that you post on the Plusnet user forum, as this is the BT Broadband forum, and the issue may be broadband related.
Your YouView box will get the Plusnet branding once the ISP configuration is updated. I assume its a retail YouView box, so it may take a while for it to download the latest update over your broadband.
