Changed screen, will not power up or connect to computer
I've changed the screen on my iPad2 the tried to test to make sure it works before sealing but it won't turn on using power button.
When I connect it to a power source (not computer) the Apple logo appears then goes, this continues to happen in a loop. Nothing else happens.
When I connect it to the computer the screen stays black. It doesn't appear as a device on the computer and the Apple logo doesn't appear.
Can anyone help
