Have you looked around the board for missing caps, resistors or filters ?
Might be stuck to the glue on the stickers you peel back.
Anything around the battery connector missing ?

Just to let you know , i had the same problem on my iphone 5S bought from auction site.

Apple logo appeared for 3-5 seconds then no image but backlight still on.
Tried new battery, new flex, new lcd.

I have solved today by replacing U2 chip with a new one and doing a restore, all is working perfectly now !
