RISOLTO: Signal very poor and 3g/ 4g doesn't work in most of time - iPhone SE

Signal very poor and 3g/ 4g doesn't work in most of time

I have bought a second hand Iphone SE 64gb. I verified it in center of my town and it worked without problems. When I arrived at home signal was very poor, no internet connection. Out of town I have same problems. I bought another sim card, another carrier/ same problem.

I checked everything and it's from my hardware. I think that logic board is the problem. Could you give me informations what to change at it? I don't find on internet any informations also I am sure that is not flex cable. I need some informations how to repair/ what to change on logic board. Thanks!!

@theelitepro_gd really Vinicus, another statement that screams "I don't have any idea of what I'm talking about, I'm just blowing something out my rear".

The likely problem is a lightning dock. After that it would be board level repair. It wouldn't serve you to just get another logic board, as it would be just as costly as a new phone
