why does my Honda Accord 10th Generation (2018-2022) dashboard screen go black randomly

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect Battery and Charging System

• Use a multimeter to check the battery voltage (should be around 12.6 volts when off and 13.7-14.7 volts when running).
• If voltage is low, recharge or replace the battery as necessary.

3. Check Wiring and Connections

• Remove the dashboard panel covering the display.
• Inspect the wiring harness connected to the dashboard screen for any damage or loose connectors.
• Reconnect any loose wires securely and replace any damaged wiring as needed.

4. Check Fuses

• Locate the fuse box and identify the fuses related to the dashboard and infotainment system.
• Remove and inspect fuses for continuity using a multimeter; replace any blown fuses with ones of the same amperage.

5. Software Update

• Connect the vehicle to a computer with the manufacturer’s software.
• Check for any available updates for the infotainment system and follow the prompts to install updates.

6. Reassemble and Test

• Reattach the dashboard panel and ensure all components are securely in place.
• Reconnect the negative battery terminal and start the vehicle.
• Test the dashboard screen functionality to ensure the problem has been resolved.
