What is the reason for the middle screen of the Audi A6 not lighting up?

Audi A6 middle screen not lighting up reasons: Possibly low voltage: If it happens occasionally, it's normal because when starting the car, the electricity is momentarily used for the ignition. If the voltage is too low, it may cause the screen not to light up. Possibly abnormal power supply: If it happens multiple times, you should check whether the power supply to the display screen is normal. If the power supply is abnormal, the power module needs to be replaced. Possibly a problem with the cable: You can check whether the cable connection is good. If there is a problem with the cable, it needs to be replaced. If the cable is normal, then the display screen may be damaged.
My Audi A6 also experienced a black screen issue with the center display before. At first, I thought it was a system crash, but restarting it several times didn't help. Later, I checked the fuses myself and found that the 15-amp fuse corresponding to the screen had blown. Replacing it with a new fuse fixed the problem. However, this incident reminded me that aging wiring can indeed cause issues, especially in cars like Audi with numerous electronic devices. If the fuse is fine, then you might need to consider whether the display itself is faulty or if there's poor contact in the wiring harness behind it. The last time I went to the repair shop, the technician mentioned that some models could also experience black screens due to a crash in the main unit's software. Now, I regularly check the electrical circuits because if the screen fails, even the reversing camera becomes unusable, which is quite dangerous.
I'm quite familiar with this issue. When the Audi center console screen doesn't light up, it's most likely a power supply or software problem. First, try forcing a system reboot by long-pressing the volume button - sometimes the system freezes like this. If that doesn't work, lift the carpet under the passenger seat to access the fuse box, then check the fuse labeled MMI or INFOTAINMENT. If it's blown, just replace it with a new one. If it's intact, you might need to inspect the circuit. A senior mechanic once told me during a repair that Audi's screen connectors tend to loosen, and prolonged driving on bumpy roads can cause poor contact. Be careful when handling the connectors yourself. If you can't fix it, it's better to visit a professional shop - they have diagnostic computers to read fault codes and identify the cause.
