Perhaps try these two things…

• Toggling ‘Off’ and ‘On’ again ‘TV Autoplay’ in the Beam room settings in the App (‘Settings/System/SBeam Room Name]’).
• Also try toggling off HDMI CEC control on any ‘other’ HDMI connected devices linked to the ‘other’ HDMI ports, besides the Beam 

…and see if that might resolve your issue.

Hi Ken,

I got it going again. Hopefully it autoStarts tomorrow morning. 

Thanks for your help.
