iPhone 6 apple logo for 2seconds then black screen backlight fail

Hey i done a housing change on a iPhone 6 i was super careful with all the screws and parts. At first it would only turn on with the charger but what is does is shows apple logo for 2seconds and then goes blank but you can see the backlight making the screen blue. I have tried all the home and power button tricks. Tried 3x batteries and 2x charging port assys and two screens it is also not recognised by iTunes. Please help thank you

"i got the same problem with a iphone 6. it was working just fine and it just happened. i have changed the screen and battery in the past.

any new info?

Update (12/31/2016)

hey, had the same problem. i changed the battery out to one that had a good charge (the current battery was dead). Itunes picked it up then. I was able to do a DFU (google it) it is back to normal."

"If you are stuck on Recovery mode, you can use 3uTools to exit this mode.

Connect your device to your PC and then launch 3uTools to see what mode your device is in."

Try cleaning the charging port of your phone first using a can of compressed air. Make sure that any dirt or debris stuck in the port is removed as this could cause charging problems. Once this is done force restart your phone by pressing and holding both the Sleep/Wake and Home buttons at the same time for at least 10 seconds until the Apple logo appears. Once this is done charge your phone using a different charging cord and wall charger for at least 20 minutes. If the issue remains then bring your phone to a service center and have it checked
