No display backlight, but there is an image

Let me briefly describe the situation. The console arrived with a problem: after installing the drivers for the graphics, the image disappeared. I reball the processor, but in the process a couple of elements on the board were unsoldered (I’ll attach a picture), now the console turns on but there is no backlight. Unfortunately, it is not possible to check the full functionality because the screen is very dark. The question is: can the missing elements be identified? I will be grateful.

And here is the datasheet for the transistor if I found the markings correctly

The bottom one looks like Zener Diode just trying to see if I can find some specifics since Z9 is not a lot to go on.

I can't make out the text on the top component, I'll have to see if I can find any other close up photos of that part of the board. Stay tuned.
