Could it be problem with the bios?

Checked with new lcd and new lcd flex, still no image.

Problem ocurred after watching netflix one night and the next day there is no display on the screen.

as hoaca388 said, the bios is not the problem, check the display, LVDS cable, connectors, video chipset..

i've flashed main and ec but no lucky: the power light keeps blinking 12 times and after turn off it restart every time in an infinite loop.
Also if i reconnect internal battery, the power light go on and after a while it turn off
the last screen before the problem was a lenovo screen with this messages: Warning: Please do not power off while BIOS self recovery processing and when it reached 100% it turned off and never turned on again.
Bios was upgraded by Windows 11 Update.
