You might want to try a new Lightning Port Flex (or one that is known-good) to see if that solves the problem. If that doesn’t work, then consider the following suggestions. Start by testing a bare-bones setup. Disconnect the battery first (always!). Then disconnect the digitizer, LCD, front camera, rear camera and home button extension flex. Now re-connect the battery; you should only have the battery and Lightning Dock flex (new or known-good) connected. Connect a known-good, preferably Apple-original Lightning cable to an iTunes enabled computer. Does iTunes recognize your phone? If so, then you should re-connect one flex at a time until the phone stops working. I would start with the Home button flex first, then add the rear camera, LCD & Digitizer then from camera flex. If the bare-bones setup does not boot, then you most likely have a logic board issue. You could send it (or find a local) to a repair shop that specializes in micro-soldering repair. Sometimes the fix can be straightforward (i.e. a blown filter) and relatively economical.
