That was an easy one. I have diode mode reading of 900 on pin 6 of J8500... R0563 is ok, 100k, line to R0563 too... it is only conneced to R0563 and CPU. Just i case i lifted U8510 and U8400 and still same reading... Could it be J8500 itself?

[@namenotfound8671]

I have some issue with backlight on MB Air A1932 where as 2inches of the right of the display shows dark backlight, can still view the image and items there it is just much darker than the rest of the screen, would this be fault with the display of the backlight panel?

@@Dusten04 thanks, man. There was an iPhone 7 plus I once worked on. As soon as I connect it to the dc power supply. It counts 0.08 even before pressing the power button. How do I fix that? Please explain more on the difference between full and half short

[@MikeJones-bb8zd]

@@Dusten04 please I just finished watching the video. Is there any value reading to tell if the phone problem is full charging ic, full short, half short, and any other fault on the iPhone and iPad. Please any useful information on that. I kinda a newbie in this field so I kinda need a strong foundational class bro.

[@MartyLEire]

If I bug you enough you make videos :p

[@Dusten04]

Of course

[@mthomas1294]

[@MikeJones-bb8zd]
