Playback Issues - Audio/Video & Power

[Rime123]

Recently upgraded from a  Roku Streaming Stick + (3810, 3811 series)  to the Roku Streambar and had it about 2 weeks now and its crashing every 2 days or so.

Seems to be completely random, watching some content and then black screen followed by the roku startup logo as it restarts.

When checking the streambar it does seem slightly warm but not excessively hot.

Any thoughts on how to resolve would be great otherwise I may just have to return it.
