What to Do When the Mercedes LCD Screen Goes Black?
2 Answers
First, check if the display cable is loose. If it is, reconnect it properly. If the cable is not loose, inspect the capacitors on the display's circuit board to see if they are burnt out. If they are, replace them. This should resolve the issue of the Mercedes screen going black. Below are some common reasons for a black screen in Mercedes displays: 1. No response when pressing buttons on the touchscreen, making control impossible. If the touchscreen exhibits 'drifting,' re-enter the touchscreen settings page to recalibrate the touch range. 2. The touchscreen displays content, and buttons respond when pressed, but control is still impossible. This may be due to a mismatch between the touchscreen RFID and the RFID set in the host program, or the wireless receiver's ID not matching the ID set in the host program.
That day, my Mercedes screen suddenly went black, and I was completely stunned. Don’t panic—first, try the simplest method: hold down the central control volume knob to reboot the system, just like you would with a frozen phone. If that doesn’t work, open the fuse box under the steering wheel (there’s a diagram in the manual) and try replacing the backup fuse related to the media system. This issue often occurs in extremely cold or hot weather, so turn off the engine for half an hour and restart it. If you’ve tried fixing it yourself two or three times without success, don’t push it—schedule an appointment with the dealership immediately. Their specialized diagnostic tool can quickly determine whether it’s a software glitch or a hardware failure with the screen. Random disassembly might damage the clips, and the cost of repairs could outweigh the benefits.
