No response after lightening jack install

The iPhone 6s Plus was not charging and eventually died and diagnosed the problem as not charging due to lightening jack connection. I just put in a new lightening jack assembly and my screen is showing no response. Does it take a long time to charge after the iPhone has been setting without a charge for 4 months or so before something will show up on the screen? Or, is this another problem? I had also replaced the battery as well.

Thanks for the reply Ben.

This iPhone has a long history of repairs. (daughter)

About a year ago it was having charging issues and black-screen problems. I did send it off to a micro-soldering shop for diagnosis and possible repair. They told me it was a bad screen and they were able to get it to charge. (I didn’t use the different cord method, ugh.) So, I replaced the screen and the battery at the same time when I got it back.

That repair worked fine and the phone was charging and working great. Then, about 3 months ago the phone stopped charging. I used all types of tricks in my attempt to make it work. After exhausting all possibilities and examining a very corroded lightening jack port, I ordered the assembly and installed it. It wasn’t an easy job, but I feel very confident that it was successful.

The new battery had not been charged for about two months or longer. That’s why I was trying to figure out what other issues this iPhone might have.

I guess the next step is to send it back for another diagnosis or just purchase another phone and cut my losses.

Thanks,
