Default Dell N5010 LVDS voltage issue

Model-Dell N5010 with Intel Graphics Only(No Ati)

Problem: Display characters are showing red instead of white.

Laptop boots fine with display-no issues other then colour issue.

Here are the voltage measured at Lvds connector(measured with Display cable plugged in and with display on screen)

Pin 01/02/03-19v
pin 04-0v
pin 05/06-3.3v
pin 07-3.3v
pin 08-3.3v
pin 09-3.3v
pin 10-3.3v
pin 11 to 23-0v
pin 24/25-1.20v
pin 26-0v
pin 27/28-1.2v
pin 29-0v
pin 30/31-1.2v

pin 35-3.3v
pin 36-3.3v
