What are the reasons for the black screen on the Cadillac CT6's central control?
3 Answers
If the central control screen goes black and does not light up, you can first try restarting the screen by turning the ignition on and off. If this does not resolve the issue, it is likely due to poor contact in the wiring, and you should promptly check for any loose connections. Other reasons for a black central control screen include: 1. Aging wiring: The power signal cable may have aged. Try replacing it with a new one. If the black screen issue is resolved, it confirms that the power signal cable was the problem. 2. Prolonged use: Extended use of the screen can cause the power supply module to malfunction, leading not only to lag but also to a black screen in severe cases. It could also be due to defects in the circuit design. However, issues like module abnormalities or design defects are beyond the scope of self-repair and require inspection, repair, or replacement at a service center.
I've seen quite a few cases of Cadillac CT6 center console black screens. The most common issue is software system freezing, possibly due to an incomplete OTA update causing a crash. Try turning off the engine and restarting, or disconnecting the battery for a few minutes to see if it comes back to life. Blown fuses are another major cause—there's an F32 position in the engine compartment fuse box corresponding to the center console screen; just replace it with a spare. Loose or corroded cable connections can also cause black screens, especially in older cars. You can check the plugs yourself for tightness, but it's best to have a technician handle wiring issues. Screen hardware failure is rare, but if the car has been in a collision or exposed to water, it might be damaged and require a replacement at the shop. Generally, address the simple fixes first, and don't let a dark center console compromise driving safety for too long.
Last year, my CT6's center console suddenly went black. While driving, the screen turned off and the audio stopped working, which was quite alarming. A friend told me it might be a software bug, and after turning off the engine and waiting for about 5 minutes before restarting, it recovered. Since then, I’ve made sure to install every system update promptly. If it’s a fuse issue, you can find the manual in the fuse box near the glove compartment, locate the one labeled 'infotainment,' and replace it—it’s not expensive. Wiring faults are more likely, especially as the car ages and connectors wear out. Try gently shaking the connection points; if that doesn’t help, take it to a 4S shop for a professional check to avoid risks. Remember to ask the technician to inspect this area during regular maintenance to prevent future issues.
