    A1706 emc3163 touch bar not working after display replacement.

    Removed the board and checked, The PPBUS_G3H has 2 ohms resistance with respect to ground. But couldn't understand who is causing the short. And the current consumption of the board is 20V and approximately 40mA (May is not accurate)
