screen does not turn on

May need a screen replacement, but before anything, I will research and add another comment later.

• Check connections
• Make sure the monitor is securely plugged in and the video cable isn't damaged. You can also try using a different cable.
• Test the display
• Connect an external monitor to the computer and restart it. If the external monitor works but the computer screen doesn't, you can try updating the BIOS, graphics driver, and CPU chipset.
• Check for a corrupted graphics driver
• You can try rolling back the display driver or adapter in Safe Mode.
• Perform a hard reset
• Unplug the power cord, remove the battery, hold down the power button for 30 seconds, and then reconnect the power cord.
• Check for physical damage
• Look for damage to the HDMI, DisplayPort, or USB Type-C port on the computer. If the port is damaged, try using a different port.
• Check the power source
• Make sure the computer is connected to a power source and the power light is on.
• Reseat components
• Try reseating the CPU, motherboard, RAM, power supply, or graphics card to make sure they're properly connected.
