I called Hisense and was told it is an issue with the Roku software. I called Roku and was given the run around basically. I've had this TV for over a year with no issues until yesterday when it started sending the message. I pulled the back cover to see if the heatsink compound had dissipated. I found 2 heatsinks that are soldered to the board and cannot be removed to apply new compound. They just smear a dab of compound on and it dissipates over time and needs to be reapplied. I see this as a cheap way to make get people to buy another tv. All computer makers make a way to reapply thermal compound to the chips. When this set dies, I will not buy another so called smart tv. I am a PC technician and I have reapplied it to both CPUs and graphics chips. INMOP this is the result of a software update gone wrong and ROKU needs to take a look at it to fix this issue with Roku TVs.
As a PC tech, have you thought of placing a cooling fan inside the TV in order to dissipate the heat. I know you shouldn't have to, but sometimes need to take matters into your own hands.
I was able to add some thermal paste to my Premiere+ (processor was under a can) and did lower temps a bit. I never received the overheating message though - more of an experiment brought up while addressing a user issue a while back.
Others have actually modified their Streaming Sticks to contain heat sinks that poke through the enclosure. (kind of like an air intake scoop on a vehicle's turbocharger). Again, shouldn't have to, but anything that can help dissipate heat is going to benefit any electrical device.
For most people, easier and recommended just to send poor performing devices back for a replacement. For others that have access to these little parts and don't mind tinkering a bit, there is this second option.
