What Causes the Camry's Central Control Screen Not to Light Up?
2 Answers
The central control screen not lighting up is usually caused by poor line contact, aging of the power signal line, etc. You can try replacing it with a new one. If the black screen issue is resolved, it indeed indicates a problem with the power signal line. The specific reasons for the central control screen not lighting up are as follows: Poor line contact: It is necessary to promptly check whether there is any loose connection in the lines. If there is, it will naturally lead to a black screen of the central control screen. In this case, simply reconnecting the loose parts properly will solve the issue. Aging of the power signal line: Because the power signal line has aged, you can try replacing it with a new one. If the black screen issue is resolved, it indeed indicates a problem with the power signal line. Excessive screen usage time: If after checking for loose connections and aging signal lines, the central control screen still does not light up, it is likely due to excessive usage time of the screen, leading to a failure in the power supply module. This not only causes lag but also severe cases result in a black screen. Damage to the central information display: This could be due to power supply issues, third-party software incompatibility with the system, or the software version being too outdated, causing system failure and inability to display normally, or screen damage. If it's not a simple issue, a vehicle inspection is needed, connecting a diagnostic computer for electrical fault troubleshooting. If necessary, the vehicle display screen may need to be replaced.
Experienced drivers who have been driving for years say that the sudden blackout of the Camry's central control screen is quite frustrating. The usual cause is a blown fuse, located in the fuse box under the driver's seat. The fuse box cover is numbered, so just replace the corresponding fuse with a new one. If the screen goes black right after starting the car, it might be due to low battery voltage or an issue with the ignition switch. Loose wiring connections are also common, especially after bumps—just gently push the connectors tight. Hardware issues like a burnt-out backlight or aging, particularly in older cars, can also be the culprit. Software glitches can cause it too; just hold the power and volume buttons for ten seconds to force a reboot. Don’t forget to check for USB port short circuits—faulty charging devices might affect the screen system. Take it step by step, don’t rush into repairs, and always prioritize safety first.
