Reasons for the Land Rover display screen not lighting up are as follows: Navigation module issue: If other systems like audio and air conditioning are functioning normally, but the screen goes black when entering the navigation interface, it may be due to problems with the navigation module or its wiring. Display screen malfunction: If the central display screen is completely black, it could be due to power supply, grounding, or the display screen itself malfunctioning. Aging power signal cable: It might also be caused by an aging power signal cable. Solutions for the Land Rover central control screen going black are as follows: Restart the central control screen: Simply restarting the central control screen may resolve the issue. Visit a 4S store for upgrade or repair: If the problem occurs frequently, it is advisable to visit a 4S store for an upgrade or repair.
Last time I encountered this issue, it was just a blown fuse located in the fuse box behind the glove compartment on the passenger side. Replacing it costs just over ten yuan. If you've recently installed something like a dash cam, you should check the wiring - any exposed wires causing a short circuit will make the display go black immediately. It could also be the infotainment system acting up; try turning off the engine, locking the car, waiting ten minutes, and restarting. In cold weather, unstable battery voltage can cause black screens too - borrow a voltmeter to check; if the battery reads below 12 volts, it's time for a replacement. If the screen is completely dead with no backlight at all, the hardware is likely damaged and the entire module needs replacing. Don't attempt to dismantle the center console yourself - Land Rover wiring harnesses are particularly complex and easy to connect incorrectly.
