Thank you very much, but what do you mean by reset? The thing is that when I turn on the matrix backlight lights up, then the backlight turns off and turns on again and then nothing happens - there is no image.

I tried to turn it on in recovery mode, but nothing changes - work only backlight. That is I can't enter recovery mode. And the thing is that I tried to flash the BIOS with the original dump (which I posted here) and the picture is the same. What could be the problem? Before flashing the BIOS, the laptop started and worked normally.

Flashed with CH341A programmer in CH341A V1.34 program

With a ch341a you have to erase the chip before programming a new bios. If the old bios isn`t booting there is something else wrong, maybe you lost a resistor or cap.
