Re: iPhone X not charging / fake charging
Alright, after further checking I managed to solve.
I double checked all [B]u3600 [/B] pads in diode mode and I found out [B]TIGRIS_PMID1 [/B] was reading OL which is not correct. Checking schematics and following the line I discovered [B]DZ3300 [/B] was burnt as well. After changing this diode [B]VDD_MAIN [/B] voltage came back to 4V with only charger which let me understand the board if fully functional.
After testing the motherboard in a socket I can say it is charging correctly.
I don't know if this might help some...Leave a comment:

iPhone X not charging / fake charging
Hello Guys,
I might need some help with this one as I running out of ideas.
Got an iPhone X dead. Customer said it was in charging and then the charger smoke and got burnt.
Upon connecting to the bench supply it was consuming 0.04a before prompt to boot but it was booting anyway. I disconnected all cables to check if any part was causing the issue but the absortion was still there. So I split the motherboard and the upper part was still getting 0.04a. After using thermal camera I found out it was tigris2 [B]u3600 [/B]which was causing the issue since it heated... -

Re: Macbook Pro A1708 820-00875 No boot
It seems that I cannot find what you told me on that battery maybe because its not original. Could you please explain further?Leave a comment:

Sorry I don't understand which one you mean but if you mean D6905 is 13V pin 1, 20V pin 2 and 19.7 pin 3...Last edited by fozzo; 05-19-2022, 02:57 AM.Leave a comment:

Macbook Pro A1708 820-00875 No boot
Hello Guys,
I have a 820-00875 board here which is not booting. Fan spin for some seconds but no boot, actually I saw it booting once but then after putting passcode screen became black and system freezed.
[B]History[/B]
Mac was working normally and then system freezed with a screen glitch. The customer then rebooted it and it started but stop after he put passcode (same behaviour wich I saw once. No prior repair on motherboard just a changed battery some months ago.
[B]Diagnosis[/B]
Checked all power lines all present as well as [B]ALL_SYS_PWRGD[/B]...Last edited by fozzo; 05-19-2022, 02:38 AM. -

Re: 820-01958-A Macbook Air 2020 A2179 No Power
I see.... so you think cpu is fried. I wonder if is safe to inject 1 volt in this line to see if anything heat but i don't think as it should be shorted to ground or if I just give back to costumer as no repair.Leave a comment:

Re: 820-01958-A Macbook Air 2020 A2179 No Power
I'm looking at [B]L8100[/B], i loose pin 2 to separate two lines
pin 1 [B]P1V1_PHASE[/B] diode is .434 resistance 17kohm
pin 2 [B]PP1v1_S3[/B] diode is .004 resistance 4.5ohm
Looks to me that pin 2 is not full short but doesn't look correct be an s3 line with low voltage, am I wrong?Re: 820-01958-A Macbook Air 2020 A2179 No Power
