    R3014 and R3015 lines are not shorted after remove. Redriver has no visible signs (inspected under 45x microscope) of burn or damage. Is there a way to test redriver or should I remove it and then check the shorted lines or just replace?

    820-00239 working without battery, burning D6902, U6903

    I was able to increase the voltage on PP3V3_G3H only to 2.955V by replacing R6910 to 200kohm resistor. If it resist more, very low voltage is generated and macbook doesn't start from charger. Did I mention that computer turns itself off only after connecting J6951 flex cable. It's working with...
