Replacing Tristar chip on iPhone 6

Hi all,

I have an iPhone 6 that does not charge nor get recognized by iTunes when plugged in. At first I thought it was the battery issue and the charging port so I replaced both. After replacing the battery and the charging port, unit still did not charge or gett recognized by iTunes. I did a little research and found out about the Tristar IC Chip might be defective and need replacement.

However, I’m not comfortable doing the repair myself as I’m not a welder, nor electrician, nor board repair technician, you name it. I’d like to find a decent, trustworthy technician that can help me replace the chip in SoCal area.

I do hope this is the right place to ask. I can delete this if this is not the right place.

Thanks in advance.
