Cause: The video card (graphics card/GPU) is responsible for handling image problems such as color, resolution, display quality, etc. If the screen does not turn on, the cause may be due to a damaged video card.

If it’s not the chipset, it’s most likely because the BIOS is out of battery or hasn’t been updated.
