I got about 85% done with my case replacement and now when i try to power it up the lower screen flashes for an instant and then shuts down. I check the touch screen and top lcd connections and they seem perfectly fine...Can anyone help?
This sounds just like that ribbon cable didn't fit well enough into it's socket..
It might seem like it did, but you have to push it all the way, and align it properly, be sure you locked it in the place too!
Just check all the connections, that is the most sensitive part!
