The reasons for the black screen of the Sagitar display may include poor line contact, aging signal lines, power supply module failure, circuit design defects, or screen aging. When there is poor line contact, it is necessary to promptly check whether there is a loose connection in the lines. If the signal line is aging, it needs to be replaced with a new one. Poor line contact: It is necessary to promptly check whether there is a loose connection in the lines. It is recommended to securely reconnect the loose position. Aging signal line: If the power signal line is aging, it can be replaced with a new signal line. Power supply module failure: Prolonged use of the screen may lead to power supply module failure. It is advisable to have it checked or replaced at a 4S shop. Circuit design defects: If there are defects in the circuit design, which are beyond one's own ability to fix, it is necessary to have it checked and repaired at a repair shop or directly replaced. Screen aging: The display screen has a certain service life. When the screen ages, bad spots and flickering may appear. Solution: Use another display screen to replace it. If the problem disappears, then a new display screen needs to be replaced.
My own Hongqi HS5 once experienced a black screen issue on the display. It suddenly went black while driving, completely unresponsive. I first tried restarting the car by turning it off and on again, but that didn't help. So, I checked the fuse box, located the display screen fuse, and found it was blown. Simply replacing it with a new one fixed the problem. If the fuse is fine, it might be a software issue. In that case, I would try entering the system recovery mode to reset it or disconnect the battery for a few minutes to let the system reset. Hardware failures are rare, but if the screen is cracked or the wiring is loose, it's best to take it to a professional repair shop. During regular maintenance, have the technician check the connections, and updating the system periodically can prevent this issue. Remember, a black screen can affect navigation and reverse camera functions, so safety comes first.
For a black display screen, I recommend starting with simple troubleshooting. Try turning off and restarting the car to see if the display recovers. If that doesn't work, check the fuses located in the fuse box under the dashboard. If a fuse is blown, replace it with one of the same specification. If the system is frozen, entering recovery mode to reset might resolve the issue. The electronic system of the Hongqi HS5 can sometimes experience problems due to software conflicts, so visiting a 4S dealership for diagnosis and updates is often a wise choice. During daily use, minimize the connection of unauthorized electrical devices to maintain stable battery voltage. Neglecting the issue for too long can affect driving assistance functions, such as the blind spot warning not working, so timely maintenance can save you trouble.
