What's the reason when the car radio display is normal but there's no sound?
2 Answers
There are three reasons why the car audio works normally but there's no sound: 1. The vehicle's infotainment system is in mute mode. 2. There's an issue with the audio being played. 3. The vehicle's amplifier system has malfunctioned. When this problem occurs, you can solve it by changing the audio source and restarting the multimedia system. Additional information: Car audio systems are installed to alleviate the boredom of drivers and passengers during travel. The earliest versions used car AM radios, later progressing to AM/FM radios, tape players, and evolving to CD players compatible with DCC and DAT digital audio. Today's car audio systems have reached high standards in sound quality, operation, and vibration resistance, capable of withstanding the bumps on rough roads while maintaining stable performance and perfect sound quality.
I've been driving for half my life and encountered radio issues quite a few times. The display works fine but there's no sound – it's downright maddening. The most common causes are accidentally lowered volume or hitting the mute button; you should first try turning the knob, and if there's still no sound, crank it up a bit. Speaker malfunctions are also frequent: loose connections or internal damage to the door panel speakers – you can take a look yourself, but don't yank them forcefully. If it's a blown fuse, locate the radio's corresponding one in the fuse box (the number is usually marked in the manual), replace it, and it should work. Wiring issues are trickier, like rainwater corrosion causing short circuits at connections, leading to signal loss. Sometimes Bluetooth or AUX input hijacks the audio – check system settings to switch back to the radio source. Rebooting is simple: turn off the engine, wait a few minutes, then restart. If none of these checks work, don't delay – head to a professional repair shop immediately to avoid missing critical alerts while driving.
