iPhone 6 blinking on/off backlight

[timvandenboo]

Hello Everyone,

I got an iphone 6 here with a strange problem.
Unit has waterdamage and came in with the following problem. Display turn of and turn on randomly. (in less than 0.5 sec) more like blinking. It can be gone for 2 hours and then it comes back.

What I already replaced:

U1501
U1502
D1501
L1503

What i tried:
Other display (Original ofcourse)
Battery
external power
checked for heat on board
checked current draw (normal)
Disconnect all the connectors
looked for shorts

Anyone an idea?
