Hello dear friends. I have an acer V5 471P and the touch screen was broken. But I instead bought the whole screen assembly and only swap the cables. And when I tried to turn it on again only with the new screen assembly nothing happened. Then I changed to the old screen assembly but still the same. No image at all. What could it be happening. Please give me you all a hand
