What Causes the Touchscreen Failure in Haval H6's Central Control Display?

[AylaDella]

Haval H6's central control display touchscreen failure may be due to damage to the touchscreen itself or a malfunction in the ADC chip that reads touch resistance values. Solution: You can use a paperclip to press the RST hole (reset button) on the DVD to restore the device to its initial state. Specific recovery methods are as follows: 1. For screen failure, use a paperclip or toothpick to press the RST hole (reset button) on the DVD to restore the device to its initial state. 2. Remove the positive terminal of the car battery, noting that generally, removing the positive terminal for 30 seconds is sufficient before reconnecting it. 3. Purchase and replace the central control display with the same model.

A few days ago, my Haval H6 also experienced touchscreen failure, and it took me a while to figure it out. The most common issue is a loose screen cable, especially after driving on bumpy roads. Another cause is prolonged exposure to sunlight, which overheats the screen, deforms plastic components, and affects the touch module. When I opened it up, I found dust accumulated at the cable interface, which can also interfere with signal transmission. Another easily overlooked factor is that a screen protector that’s too thick or has air bubbles can reduce sensitivity. If the entire screen is unresponsive, consider a possible main control chip failure. Lastly, try turning off the engine for ten minutes and restarting—sometimes it’s just a system freeze. If you’re DIY-ing, start by cleaning the screen thoroughly. If that doesn’t work, take it to a 4S shop for circuit inspection.
