iPhone 6 - Replaced entire backlight circuit still no backlight

iPhone and Apple Products Hardware Repair - GSM-Forum - forum.gsmhosting.com
Originally had one shorted output capacitor and burnt diode, and coil.

Replaced all three - no backlight

Replaced u1502 - no backlight

Measure vcc 3.9v on backlight anode

Replaced u1502 three times still nothing

All filters are good. There is a display but no backlight.

Anyone experience this before?
