IPhone 5c screen replacement

[oddbod73]

Hi all 2nd time I've replaced daughters screen, 1st time was fine no issues, this time however the screen has the back light on & nothing else when I connect to the power cable the phone constantly vibrates. I've checked all the ribbons etc all connected, any help appreciated! Thanks

Did you disconnect the battery while performing the change over?

Try a hard reboot - hold the power button and home button together until the phone turns off, then continue holding until it turns on again.

If you're unable to tell if the phone is turning off/on, simply hold the two buttons together for a full two minutes.

While connecting the ribbon cables, did you do that for more than once/connector?

It may be the so called "gold finger" of the connector is deformed, check it up!
