How to Restart a Mazda Display Screen When It Goes Black?
4 Answers
Mazda display screen black can be restarted by re-igniting the engine. The following is the relevant introduction about Mazda maintenance: 1. Check the antifreeze: The amount of antifreeze must be appropriate. The maintenance station recommends changing the antifreeze every two years, but mixed antifreeze (especially those with water added in summer) must be replaced annually. Note that products of different brands and models should not be mixed. Next is the engine oil. The lubrication requirements for the engine are higher in winter. If summer engine oil is used, it must be replaced. Engine oil that has been used for a long time, turned black, or has poor adhesion should be replaced to ensure smooth engine start-up. 2. Replace with higher-grade gasoline: If you usually use 90-grade gasoline, you can switch to 93-grade. Because the ambient temperature for car use in winter is lower, higher-grade gasoline has a higher ignition point and slightly stronger ignition capability.
I remember my Mazda screen also went black before. At that time, I tried holding down both the music button and navigation button on the center console for ten seconds, and the screen restarted. If this trick doesn't work, I would turn off the engine, get out of the car, lock the doors, wait for five minutes, and then restart to let the system cool down and reset itself. If that still doesn't help, I'd have to open the hood, locate the battery, disconnect the negative terminal for five minutes, and then reconnect it. However, after disconnecting the battery, the clock needs to be reset, and the seat memory is lost. Usually, it's important to avoid using low-quality chargers in the USB port, as unstable voltage can easily cause the screen to freeze. Also, the system tends to lag after being exposed to the summer sun, so try to park in the shade. If the screen keeps going black, it's necessary to go to the 4S store to check the wiring or update the system.
When encountering a black screen, I first press and hold the volume down button on the left side of the steering wheel and the phone button on the right side for ten seconds, which usually succeeds in restarting it. If that doesn't work, I turn off the engine and step out for a smoke break to let the car completely power down. There's also a hardcore method: open the engine compartment, locate the fuse box, pull out the 7.5A fuse for the entertainment system, wait three minutes, and then plug it back in. Before performing these operations, make sure the dashboard lights up normally—if even the dashboard is black, it might be a blown fuse. It's recommended to clean the screen connector interface with a damp cloth every six months, as oxidation and poor contact can also cause black screens. If you've modified the reverse camera, pay extra attention to potential wiring interference issues.
When the screen is black, press and hold the return key and mute key on the center console without releasing. The screen usually restarts within ten seconds. If it doesn't work, turn off the engine, lock the car, and wait ten minutes before trying again. During this time, do not open the car door to ensure the vehicle is completely powered off. If it still doesn't work, disconnect the negative terminal of the battery for five minutes. Prepare a wrench before operating, as the power windows will become inoperable after disconnecting the power. If the screen appears red or flickers after restarting, it may be a ribbon cable issue. Avoid pressing the screen on bumpy roads while driving, as vibrations can loosen the motherboard connectors. For vehicles over five years old, it's recommended to check the capacitor lifespan, as aging capacitors may not withstand voltage fluctuations, leading to black screens.
