First, thank you for this video on youtube. Second, ask a big favor, to see if I can solve a problem with a Huawei Y7 2018. This cell phone is shown however, however, if the organization is done after doing ultrasonic cleaning. I attached the only plans that are on the internet: https://postimg.cc/ctTsy2wB https://postimg.cc/4nRQWdP1 https://postimg.cc/1gzWDpHm https://postimg.cc/V59Bp8HP https://postimg.cc/gLdVmJ7F Could you confirm that at the output of the Shottcky diode, from the image called "lcd2", there are 24 volts? In some of his videos, he heard that the coils are never grounded, or that some backlight coils have some ground coil, although it is not usual. Can you tell me in this case, in the image called "lcd2", the coil marked with a red circle, could it be grounded? Because I checked it on the Y7 that I'm trying to repair, yes it is, although the Coil is located underneath it, it is not. If this coil was defective, could it be the cause of the output of the PMI8940 not being in the 24 volts of the Backlight? Because when I measured it, I only got 4.7 volts. Is the PMI8940 defective or is it a problem with the coil? I hope you share your wisdom with all those who do not dedicate ourselves, with greater or lesser fortune, that is, the reparations and what can be given a little light in the resolution of my problem. Regards, and thank you very much. | |
