iPad 4th A1460 logic board noise , completely dead will not power on
I was replacing broken digitizer ( i guess thats my 4th time ) but this time i messed up FPC LCD connector on Logic board so thats need replacing , but
i have actually , carefully but completely remove ( stripped down ) LCD connector from PCB , and all soldering pins looks ok, Now obviously iPad LCD screen in not connected so i am only relaying whats showing in iTunes . So before i completely remove FCP connector from logic board iTunes was still able to detect iPad as normal , then for a while : with FPC connector already removed iTunes was not detecting my iPad , only if i put it recovery mode, then i try detaching Logic board form battery , all connector ,putting it all back together etc. and now iTunes not detecting it at all , not even in recovery mode!
Also tried reiboot mac app , to get out of look ,but reiboot also not detecting it.
I don't think battery getting charge when connected to apple charger .
Tried few different cables , all good tested on my other apple devices.
Ipad dock connector i think its fine ,
The only sign i get from iPad is when i connect to charger there is some very weak not very noticeable ,but high pitch type of sound /noise coming from logic board , from around A6X chip or even down below where dock connector on logic board is ,hard to say as its really really weak and its all over , i guess that is proof that its getting power to logic board from charger.Its not happening when its only connected to battery ( which are probably drained and not being charged , even if left charging all night )
Is this a good question?
