Roku Streaming Stick starting overheating after installing the latest upgrade
I've been using my Roku Streaming Stick model 3810x for over a year now without any problems. But since installing the latest software upgrade 11.0 - build 4184-50 I've been getting overheating error message
Sometimes it is a coincidence when an issue develops and it coincides with an OS update. Other times, it is not.
Are you using the HDMI extender available for free from Roku (https://my.roku.com/hdmi#!) that will help to give you a little more distance from the heat of your TV. You can also just make these yourself. Just place it between the TV and the Streaming Stick. (These may be currently backordered as other cables so may just have to purchase in-store or online - just a female and male HDMI connector cable.) Looks like these cables.
Some users have also reported using the power adapter directly plugged into wall helps in some situations if you are currently plugged into the TV's power USB port.
