What are the reasons for a car not starting and the screen flickering?
3 Answers
Here is an introduction to the reasons why a car may not start and the screen flickers: 1. Circuit or electronic failure: blown fuse, open circuit in the high-voltage coil, open circuit in the low-voltage circuit, detached central ignition wire, leaking distributor head, damaged spark plug. Electronic failure mainly refers to the malfunction of the central computer control board. 2. Fuel system failure: stalling caused by fuel system issues often presents symptoms such as weak engine power and a soft accelerator pedal. Possible locations of fuel system failures include: malfunctioning fuel pump, blocked fuel line, clogged fuel filter, failed carburetor, damaged injector, etc. Sometimes, it could also be due to an empty fuel tank that the owner is unaware of. 3. Mechanical failure: broken timing belt (chain), cylinder leakage with no pressure, etc. The second scenario is when the starter does not work or barely functions. In this case, the first thing to check is the battery or accumulator.
My car had the same issue the other day—it wouldn't start, and the screen was flickering. It's mostly due to a weak battery. Either the battery is old and can't hold a charge, or you forgot to turn off the lights, draining the power. The screen flickers because of low voltage, causing the onboard computer to act erratically and fail to boot. This problem is especially common in cold weather or if the car hasn't been driven for a long time. The solution is to ask a friend for a jump-start, then drive around to recharge the battery. If the battery's lifespan is over, it's best to replace it early to avoid worse issues next time. Screen flickering might also be triggered by the anti-theft system—try unlocking with the key and restarting. In any case, avoid forcing a start to prevent damaging other components. Developing a habit of turning off electrical devices can help prevent such problems.
I've had a similar experience - failure to start plus flickering screen. The first things that come to mind are insufficient battery voltage or connection issues. It's normal for battery performance to degrade after several years of use, and corroded/loose wiring can also cause power interruptions. Additionally, a faulty alternator that can't charge properly may cause voltage fluctuations leading to screen flickering. My suggestion is to first check battery terminals to ensure they're tight and corrosion-free, then measure voltage with a multimeter - avoid repeated ignition attempts if it's below 11 volts. For prevention, have battery health checked during regular maintenance and avoid prolonged parking. Loose alternator belts or regulator failures can also cause problems - get them fixed promptly to prevent bigger troubles.
