I have professionally replaced (litereally) hundreds of iPhone 6 and 5s Assemblies and LCDs however after replacing my first 6s with an OEM assembly I clicked the power button and the screen showed up perfectly then dissappeard an will not power back on. I have replaced the screen I have replaced the button I have installed with the battery disconnected I am using all the original cables and buttons I have tried soft resetting This phone connects to iTunes perfectly and periodically i can click the side or power button and see the screen for a split second again before it turns back off and wont power again. Please Help!
Have you tried putting the old screen back on, to rule out the new screen being an issue?
