Patrik. I happen to have exactly same problem with a P5110 I have for repair: all voltages except for 2 are ok. The 2 off are exactly the same wrong voltage of 0,9V. I have done, according to samsungs service manual, a replacement of U701. Unfortunately the problem is exactly the same with the new chip in place. Next thing I will try is to swap out the oscillator OSC700. I will keep you posted with the results in the coming days.
