Hello.
I have a Philips Android TV model 40PFH550/881.
When ever I try to cast to it from my S8+ or from crhome with w10, the TV restarts.
The current Softward Version is: QM152E.0.7.70.0
I can stream the desktop, youtube etc without a problem.
The issue is when I am choosing cast "Source"
I can't find any information about this specific issue.
Can't comment on your specific issue, but the HBOGO Android TV app has had various issues over its lifespan with different Android TVs/boxes, so I'm not surprised
