Sorry Q9706 PIN 1: 0.02v 30 sec Powering unstable. 1.82v PIN 3: 8.05V 30 sec Powering unstable. 12.7V PIN 4: 12V.Q9706 is being told to turn on. What is on pin 4 and what is on pin 6?
When there is 8V on pin 3 and 12V on pin 4 there should be 12V on pin 1. Looks like a bad Q9706 to start with, but check that LCD_BKLT_EN is high.
