won't boot and apple logo disappears after 3 seconds PLS Help

my friend gave me an iPhone 6 that won't turn on. I'm a tech savvy person so i thought i might fix it and give it to my dad. the phone flashes an apple logo at me for 3 seconds then disappears but the backlight remains on. I've tried iTunes restores as iTunes recognizes the device. heck I've even tried dfu mode and rec boot but it still cuts off. I've tried a new em battery and a new oem charge port. and a new screen and charge all night. pls help me get this up and running

was it water damaged?

no actually all signs clear. :(

Not enough info to diagnose this phone and it might be just about anything. Has it been dropped or repaired before?

not dropped but i know quite a bit about phones and I've tried all i know and its beyond me now lol I've already tried a new battery. I've gotten it to be in a visual recovery screen now but i still get error 9. charge port was replaced as well by me that did not fix anything.

it was 3rd party lcd but the ports look clean and ive used an oem screen

Well it could very well be a hardware problem.Let's try changing the wifi antenna.Reason is that when your phone boots up at the logo it checks its hardware and one of the first pieces it checks is the wifi antenna and if it asks wifi to respond and it doesnt it will stay at boot forever,if that dont work check some of the other hardware components that are easily damaged.

Basically the phone dont boot past the logo because all the parts arent checking out,so theres a problem in the hardware.Its just a matter of trial and error from this point on.Start by replacing some of the cheaper parts first,you never know you might get lucky.Its usually a board issue from my experiences though.
