[Davis]

Hi guys, I got this MBP 15 retina, red light on jack, I have replaced the part (seperate from boardr) and i still get the red light..what can cause it on MLB?

EDIT: I have replaced the R6895 red light is gone and sound is back, both on speakers and headphones. (Port B detect SPDIF Delegate)
