The car screen not lighting up can be caused by many reasons. The car display screen not only provides access to navigation, reverse camera images, vehicle fuel consumption information, but also offers a variety of multimedia entertainment systems for operation. It not only provides convenience to the occupants but also enhances the interior aesthetics. However, if the car display screen malfunctions, the inconvenience it brings to the driver will be obvious. Therefore, if there is an issue, it should be checked and repaired promptly. Next, let's take a look at the possible causes. 1. Check whether the screen is damaged, the wiring is faulty, or the IC and motherboard caused a crash. This is the most common issue. If it's a hardware problem, you can only take it to a 4S shop for maintenance or to a repair shop for inspection. 2. Check if the software version is outdated or not updated in time, which may cause the display screen to malfunction. If so, simply upgrade the software version. 3. If the DVD operation is lagging and the car display screen does not light up or respond to touch, try restarting the power supply of the car screen. 4. Third-party software is incompatible with the system. Check if any new software has been downloaded recently. A crash may be caused by unstable programs or insufficient memory. In this case, you need to free up some memory and uninstall the related software. 5. Finally, if many methods have been tried and still don't work, the only solution is to perform a car diagnostic test and replace the navigation device with a new one.

What are some ways to relieve fatigue from long hours of driving?

There are several methods to alleviate fatigue from long hours of driving: 1. Adjust your visual focus: When driving for extended periods, avoid staring at the center line of the road. Instead, shift your gaze and, when safe, look into the distance to relieve eye strain. 2. Use lemon to invigorate your body and mind: Keep a lemon within easy reach. When feeling tired, lightly scratch its peel and take a deep breath to inhale its refreshing aroma, which can help refresh your mind. 3. Listen to music and sing along: Driving can easily lead to fatigue. Listening to your favorite upbeat music and singing along loudly can help relax your mind.

Can a Dash Cam See Inside the Car?

A dash cam cannot see inside the car. The lens of a dash cam is designed to capture the view in front of the vehicle or the surroundings, but it does not record the interior of the car. The primary function of a dash cam is to record video and audio of the entire driving process, which can serve as evidence in the event of a traffic accident. Dash cams are responsible for recording the road conditions in front of the vehicle, and some models can also record both front and rear views. However, whether it's a single-lens or dual-lens dash cam, none can see or record the interior of the car. While driving, the dash cam continuously records video, along with time, speed, and location data, functioning much like a "black box."

What are the reasons for the overflow of the expansion tank?

The reasons for the overflow of the expansion tank: 1. When the engine temperature is too high, the coolant will boil and overflow from the expansion tank cap due to excessive pressure. The cause of the high engine temperature should be identified and addressed; 2. The water temperature is too high. During driving, cooling relies on natural wind and the fan. After stopping and turning off the engine, the fan stops working; 3. Blockages in the radiator or hoses, or leaks in the radiator cap or the cap connecting to the engine. The car radiator, also known as the heat exchanger, is a key component in the car's cooling system, functioning to dissipate heat. The radiator is usually located behind the air conditioning condenser. Opening the engine compartment only reveals the upper cover of the radiator. To see the radiator's position, the front bumper cover needs to be removed.
