I changed the power supply, changed the HDMI cable - it did not help. I installed a WiFi repeater (the Internet is quite fast) - it did not help. Opened the body of the device. The ventilation holes are filled with plastic (the Chinese let us down). Cleaned them up, didn't help. I installed additional heatsinks for memory, replaced the thermal pad on the CPU, attached an external fan from the processor of the old computer to the case and made high legs - it didn’t help (although the temperature in the operating mode was reduced from 73 to 52 degrees) . The shaitan-box both hung and freezes . Looks like either the firmware is a curve or, more likely, the memory chips are buggy . However, given the price, it's easier to pick up and buy another TV box than to fight further with this monster . .
