What Causes the Camry's Central Control Screen Not to Light Up?

[Carson]

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be due to power supply issues, third-party software incompatibility with the system, or the software version being too outdated, causing system failure and inability to display normally, or screen damage.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.
