There is no image on the screen when replacing a new matrix, what could be the problem?

Question

Samsung

In general, things will go like this:
There is a Samsung NP550P5C laptop with a broken matrix. I opened the screen to see the matrix model, the model is LTN156KT06-801. I went to look on the Internet for an identical matrix to buy. I found a model matrix - LTN156KT06 801 BA59-03144A, the price turned out to be 8 tr (I was a little surprised, spat, but ordered). Came well packaged, immediately ruled out the possibility of breakage during transportation. I replaced the matrix, as expected, pulling out the battery, carefully. I turn on the laptop, only the backlight of the screen lights up, there is no picture. I thought I screwed up with a train, I decided to put back the old, broken one. Put, the result is the same as before replacing the matrix, the picture is in places where the matrix is ​​​​not broken. Now I'm wondering what's wrong with the matrix? There is no opportunity to insert it into another laptop, I live alone, in a village far from civilization, there are no SCs in the nearest ~ 100 km and no,
Zs: the maximum is the ability to connect a laptop using HDMI to a TV, but what to watch there, I don’t have tea in my heart. I hope for your help and responsiveness

Answer 1

Answer 2

resolder the matrix flash drive from the broken one.
