Dark MCU Screen Repair 2012-2016 Model S

If your Tesla Model S MCU screen takes a long time to load or does not work at all, this is an indicator that the memory of your onboard computer is full. So, you need to change the flash chip on the Media Control Unit (MCU). The onboard computer contains a flash memory chip (eMMC) that can only be written a limited number of times, before data gets corrupted. You can either wait for failure, or proactively replace and upgrade this flash chip with a more industrial, high-endurance version flash chip, with 4 times the memory.
