I bought a Xiaomi mi box S prefix. After turning it on, it works for about an hour or a little more, but then it turns off. At the same time, the Internet works, the video plays normally.
If the set-top box works for a while and then turns off, then the problem may be a heavy load on the memory. You can reset the set-top box to factory settings or free up space on the set-top box by transferring it to another drive. Similarly, the cooling of the set-top box does not cope with its tasks. Therefore, overheating occurs and the prefix is \u200b\u200bturned off. The first thing to do is to clean the TV box from the inside. For 100% certainty, I advise you to buy a small cooler and install it next to the console.
