What Causes the Black Screen in Mercedes-Benz E300?
1 Answers
Reasons for the black screen in Mercedes-Benz E300 navigation system: Complete black screen without powering on: First, check if the car fuse has blown. If the fuse is burnt out, replace it. Also, inspect whether the navigation buttons are stuck, including the RSET button, as stuck buttons can also prevent the system from powering on. Black screen with normal sound: Tap the touchscreen to see if it responds. If the touch function works normally, then the issue lies with the display screen itself. If the touch function is not working, check the touch circuit. Generally, this could be due to the decoder chip or core module not functioning or being damaged.
