Lenovo 330S-15ARR 81FB Schematics (no video)

Hi I'm trying to figure out whats the matter with my laptop Lenovo 330S-15ARR-81FB. I need the schematics to figure out if the bios is "OK" and which component are damage. the laptop start, fan i running, led light is white and charger is working, keyboard light is working perfectly, Caps look light and num lock light doesn't work, no video. I press FN + R and the charger light start blinking 3 times and keep blinking in a endless loop.

Please I need the schematics and if you can give any help I would appreciate...

The screen is black (no video). When I press FN + R and power bottom, charger led start blinking, keyboard lights turn on and turn off. and it doesn't finish as expected.

I'm using a USB FAT32 format, GPT, and the file posted in this forum.
Battery is fully charged
