  • iPHone 6 Plus - No image/no touch and wont start/charge with USB charger.

    iPHone 6 Plus - No image/no touch and wont start/charge with USB charger. I have grey backlight n the screen. The screen is brand new , tested with two screen and same thing. NO IMAGE!
    1. I've checked for short on all components, but nothing gets hot.
    2. I have 1.8v on Reset signal on U1501
    3. L1500 pin 2 is showing 3.8v (on my bitmap it says it should be 18VO_MESA_SW...... So is 3.8v to low?
    4. I checked the connector J2019 and all rails and power lines are good.
    5. I have PP1v8 on J2019 Pin35
    Any suggestions?
