If the power light doesn't light at all (green one) and neither screen flashes the fuse marked F2 by the battery terminal has blown. If the upper screen flashes but the lower one does not then the lower screen is not seated properly and visa versa. The dog ears on the ribbon cables need to be pushed in tight and squared with their socket. If you pay attention there is a white line on the motherboard. They need to be behind it and parallel with it. The black hinge that holds them in needs to be flat and straight, some times they pop out in the middle.
