Hi @angelrangel
If there are no images to be seen on the laptop screen even when using a flashlight connect an external monitor (TV?) to the laptop's HDMI port and check if there's still a display from the laptop seen on it. Don't forget to press the F7 key to access the display output options.
If the external display is OK then hopefully it may only be a damaged video cable. The video (EDP) cable passes through the hinge to get from the motherboard to the screen.
Here's the [https://download.lenovo.com/consumer/mobiles_pub/ideapad3_hmm.pdf|hardware maintenance manual] for the laptop that may help.
The EDP cable is first mentioned on p.48 in the removal procedure that eventually gets to removing the LCD panel.
If the EDP cable is damaged then usually the cable part number can be found printed somewhere on the cable itself. Once you find it, search online for the part number to find suppliers that suit you best.
If the cable isn't damaged or if it is and it has been replaced and there's still no display but there is a display seen when using the flashlight, check if fuse FG3301 is OK and not blown. If blown search online for [https://www.digikey.com/en/products/detail/panasonic-electronic-components/ERB-RD3R00X/2796787|ERBRD3R00X] (supplier example only) to find suppliers that suit you best. You can check if it is blown by testing for voltage on pins 1& 2 of the motherboard's EDP cable socket.
