Okay so i normally fix ipod 2nd and 3rd gens and thought i would give a 4th gen ago.

Iam replacing a digitizer +screen which are both connected, during removal i broke the wifi antenna cable.

I then continued to follow the instruction following every step making sure that i wouldn't brake anymore ribbon cables.

I believe that i have NOT broken any other cables but the ipod will not power on ?

Could anyone help me with this would the broken wifi antenna result in the unit not powering on ?

Any help would be greatly appreciated

Thanks guys , turns out that when i but the logic board back down the lcd was coming loose without me realising , pretty silly to be honest but thanks for the responses :)
