How to Deal with Cadillac Black Screen?

[ConnorRose]

If the central control navigation screen goes black and does not light up, you can try restarting the navigation screen first. It might be due to aging power signal cables, so you can try replacing them with new ones. It could also be caused by prolonged screen usage, leading to a malfunction in the power supply module, which requires inspection and repair at a 4S shop.

I encountered a black screen issue while driving my Cadillac ATS. The navigation suddenly went black, which was quite alarming. I tried holding down the volume and settings buttons below the screen simultaneously for ten seconds, and the system automatically rebooted and recovered—pretty straightforward. If a reboot doesn’t work, check the fuse. Open the fuse box near the engine compartment, locate the fuse labeled 'Display' or 'Infotainment,' and see if it’s blown. If it is, replace it with a new one—it’s not expensive. Avoid using aftermarket devices to prevent voltage instability and short circuits. Most black screen issues are minor power or software glitches, so don’t rush to repair them. You can solve about 80% of the problems yourself; only go to the 4S shop if absolutely necessary.
