What to Do When the Peugeot 408 Screen Is Unresponsive?

Due to poor line contact, it is necessary to promptly check whether there is any loose connection in the circuit and properly reconnect the loose parts. If the power signal cable is aging, you can try replacing the power signal cable. If the screen has been used for too long, causing a failure in the power supply module, take it to a 4S shop for inspection or replacement of the power supply module. If there is a defect in the circuit design, take it to a repair shop for inspection and repair or direct replacement. If it is still under warranty, claim the warranty.
When encountering an unresponsive Peugeot 408 screen, my first reaction is not to panic and try restarting the system. I've dealt with similar issues before, and most of the time it's just the software freezing, possibly due to high system load or an occasional bug. You can turn off the engine, wait for two or three minutes, and then restart it to see if the screen recovers. If there's still no response, it might be a hardware issue, such as a malfunctioning screen or loose connection cables. I recommend checking the car's fuse box, locating the corresponding fuse to see if it's blown—replacing it might solve the problem. Don’t forget to check if there are fingerprints or dust on the screen surface; cleaning it with a soft cloth might also improve touch sensitivity. If none of these steps work, it's best to visit a Peugeot specialist as soon as possible for diagnosis to prevent the issue from worsening and affecting navigation or entertainment functions. Regularly keeping the system updated can help reduce such troubles.
