What are the reasons for the Corolla's center console screen not lighting up?

The reasons for the Corolla's center console screen not lighting up are as follows: Poor line contact: The center console screen may not light up largely due to poor line contact. It is necessary to promptly check whether there is a loose connection in the lines. If this is the cause, it will naturally lead to a black screen on the center console. In this case, simply reconnect the loose part properly. Aging of power signal lines: Of course, it may also be due to aging of the power signal lines. You can try replacing them with new ones. If the black screen issue is resolved, it indicates that there is indeed a problem with the power signal lines. Failure of the power supply module: There is also the possibility that prolonged use of the screen has caused a failure in the power supply module, resulting not only in lag but also in a black screen phenomenon.
I've been driving a Corolla for almost ten years and have encountered the issue of the center console screen not lighting up several times. Generally, there are a few main reasons: the most common is a blown fuse, which can be found in the fuse box under the steering wheel or in the engine compartment—just replace it; loose or aging wiring connectors are also frequent culprits—like the time my plug wasn't inserted tightly, and it worked after re-plugging; the screen itself might be faulty, such as a backlight panel failure or touchscreen malfunction, which are more likely with prolonged aging; insufficient vehicle battery power or unstable voltage can also cause this, especially in cold weather; occasionally, the system may freeze, and turning the car off and on again can restore it. I think it's best to first check the fuses and connections yourself—it doesn't cost much, but ensuring safe driving is crucial, as losing the navigation and rearview camera when the screen is off can be very dangerous. Actually, it's similar to headlight issues—both are electrical problems, and regular maintenance can help prevent them.
As a car enthusiast who often tinkers with infotainment systems, I've found that there are quite a few reasons why a Corolla's screen might not light up. For instance, a blown fuse is a basic issue—try replacing it. A short circuit or damaged wiring could also cut off the power supply. If the control motherboard malfunctions or the software freezes, the screen may go black. Overheating due to high temperatures or excessive dust buildup can affect heat dissipation, and an aging battery might cause unstable power delivery. Personally, I'd open it up to check the connections—if nothing's loose, I'd attempt a hard reset by holding the screen's power button for 10 seconds to see if it responds. If the problem persists, using an OBD tool to check error codes can help pinpoint issues with the wiring or control modules. I'd advise against attempting repairs blindly to avoid damaging the circuits; consulting a professional technician is the most hassle-free solution. Nowadays, smart screens are more delicate, so minimizing the installation of third-party software can help reduce bugs.
I drive a Corolla to work every day, and the screen suddenly not lighting up is very annoying. The main reasons could be a blown fuse—check the relevant fuse in the fuse box under the seat; a malfunction in the screen itself or loose wiring; weak car battery voltage unable to keep up; or the system freezing and needing a reboot. I suggest turning off the engine first, waiting a few minutes, then restarting. If that doesn't work, check the fuse and replace it yourself. If the issue persists, you should visit a repair shop to avoid driving hazards—no backup camera when the screen is off is quite dangerous. Simple troubleshooting can solve most problems.
