How to fix the black screen issue on Cadillac XTS?

Due to poor line contact, it is necessary to promptly check whether there is any loose connection in the wiring. If found, the wires need to be replaced. It could also be because the power signal cable has aged. You can try replacing it with a new one. Another possible reason is prolonged screen usage, which may cause a failure in the power supply module, requiring its replacement. There might also be a defect in the circuit design. However, such design flaws require inspection and repair at a service center or direct replacement.
My Cadillac XTS also experienced a black screen. As someone who enjoys tinkering with cars, I'd like to share some tips. First, check the simple issues: restart the car after turning it off and wait a few minutes to see if the screen recovers—sometimes the electronic system cache gets full and freezes. Next, inspect the fuses; look for the corresponding fuse box under the driver's seat or in the engine bay—replacing a blown fuse is very cheap. Software issues are common; try a button combination reset, such as holding the volume knob and power button simultaneously for 10 seconds to force a reboot. For hardware, feel if the screen is overheating—excessive heat might indicate a motherboard failure. If that doesn’t work, back up your data and upgrade the system version. As a preventive measure, check the tightness of connection cables monthly to avoid dust buildup. Most issues can be fixed with some DIY troubleshooting, but a broken screen requires professional inspection.
