Why won't bios load???

Question

Iron

Good day to all!
I have such a problem ... Previously, the laptop worked every other time, took it to those. service! I brought it, and now only the backlight of the monitor and indicators work. At startup, only the backlight lights up, even there is no bios and no logo.
I dismantled the laptop, everything is in place, the matrix too ...
What could be the problem ???
And then they took 2k from me and only aggravated the problem =(

Weird question! Take it back to the service that brought it to such a state. I don't understand why you took it apart.
