What causes the central control screen of the eighth-generation Accord to not light up?

The reasons for the black screen issue on the central control screen of the eighth-generation Accord are as follows: Poor line contact: You can first restart the screen by turning the ignition on again. If the problem persists, it is likely due to poor line contact, and it is necessary to promptly check if there is any loose connection in the wiring. In this case, simply reconnecting the loose part properly should resolve the issue. Aging signal cable: Of course, if the power signal cable has aged, you can try replacing it with a new one. If the black screen issue is resolved, it confirms that the power signal cable was indeed the problem. Power supply module failure: If the above two scenarios have been checked and the central control screen still remains black, it is likely due to prolonged usage of the screen, causing a failure in the power supply module. Of course, this could also be due to a design flaw in the circuit. However, issues like module abnormalities and design flaws require inspection, repair, or direct replacement at a repair shop.
It's really annoying that the central control screen of my eighth-generation Accord suddenly went black. I've encountered this issue several times, and the most common cause is a blown fuse. The Accord's fuse box is located under the steering wheel on the driver's side. Open it and look for the fuse labeled 'central control' or 'audio,' then pull it out to check if the metal wire inside is broken. Replacing it with a new one usually solves the problem, and you can buy a new fuse for just a few dollars at an auto parts store. If the fuse is intact, the screen itself might be aging, especially the LCD backlight in older models, which is prone to failure. If you're handy, you can disassemble it to check for loose or corroded connections. Sometimes tapping around the screen can temporarily restore the display. Additionally, a weak car battery with unstable output can also affect the screen. Use a multimeter to measure the voltage; if it's below 12 volts, the battery is likely failing. Another common issue is improper wiring after installing an aftermarket navigation system. Try restarting the car or disconnecting the negative terminal of the battery for a few minutes and then reconnecting it. For prevention, regularly clean the contacts to protect against moisture.
I've driven an eighth-generation Accord for many years, and the central control screen not lighting up is often due to electrical circuit issues. First, check if the fuse is blown and replace it by locating the corresponding position in the fuse box. Aging wires or short circuits are the main causes, especially during the rainy season when high humidity leads to corrosion, resulting in power interruption. Relay failure may cause unstable power supply; use a multimeter to test if there's voltage at the central control interface. If the battery output is low after starting the vehicle, the screen may flicker or not light up—test the battery to see if it needs replacement. Additionally, a faulty control module can also cause this issue; check if the software has a reset button. If you're not familiar with electrical circuits, don't force it—seek professional diagnosis for safety. Also, pay attention to improperly wired aftermarket equipment.
My Accord's center console screen occasionally doesn't light up. My first thought would be whether I accidentally pressed a button, as some buttons can turn off the screen. Try pressing the volume up button or holding the power button for a few seconds to restart. Freezing of the infotainment system is common; try parking, turning off the engine, and waiting five minutes before trying again. If the brightness in the screen settings is turned down too low, it might be invisible, so check the menu and adjust it. Restarting the engine often works if there's no battery issue. As the car ages, screen failures due to aging naturally occur, but don't worry, most are temporary issues. Regularly keeping it clean prevents dust from entering the wiring ports.
