Why did the central control screen of the Refine M3 suddenly go dark?
2 Answers
The reasons for the central control screen not lighting up are as follows: 1. The central control screen system may have frozen due to extreme high or low temperatures causing abnormal operation of system components. The screen will return to normal once the vehicle temperature stabilizes. 2. The central control screen might have been manually turned off after starting the vehicle. Simply press the power button to turn it back on. 3. The fuse for the vehicle's central control screen may have blown, cutting off the power supply. Replace the fuse in the engine compartment fuse box. Solutions: 1. First, check whether the power supply to the display screen is normal. If not, replace the power supply module. 2. Then, check if the ribbon cable connection is secure. If there's an issue, replace the ribbon cable. 3. Check whether the display screen is damaged. Test by replacing the display screen. If it returns to normal, the display screen is damaged. If the issue persists, with normal power supply and secure ribbon cable connection, check whether the motherboard's video output is functioning properly.
My JAC Refine M3's central control screen suddenly went dark a few times. This could be a power issue, such as a blown fuse. Just locate and check the relevant fuse in the fuse box under the dashboard and replace it if necessary. Poor contact in the wiring is also common, where loose or oxidized connectors cause power loss, requiring panel removal to tighten them. Software freezes can crash the system—try turning off the engine, waiting two to three minutes, and restarting the vehicle. Hardware issues like damaged screen backlight panels are less likely but still need to be checked to avoid damaging other components by haphazard disassembly. It's recommended to power off and save settings before turning off the screen daily, and have a technician inspect the circuits during regular maintenance to ensure the navigation and air conditioning function properly. Don't rush to spend money on a replacement—most issues are minor, saving both hassle and costs.
