My Roku stick keeps overheating. I used the free HDMI extender and that didn't stop the problem. I then purchased an HDMI extender that is 3 ft long. I still got the "Overheating message" about 2 hours into viewing. The stick is not located near any other devices or in the sun. Serial number is CT3944608739. Please don't answer with your stock reply of get a free HDMI extender.
