Yes, sorry, I also tried that, no go. I ran an apple diagnostic, no errors found. It does the apple recovery just fine, but this only happens when trying to boot using the internal SSD.
I also tried verbose and single user mode. Still same issue. I took a video of what it says during verbose...
My Reference only: TT10294
Problem: When booting, only Apple logo displays, and stays this way, occasionally you will get a error where you have the power off watermark in the background saying the computer rebooted because of a problem, and to press any key to reboot or it will reboot itself...
Diode mode:
PP1V25_PMICVREF .888, its supposed to be .480.
P1V2_PHASE .086 supposed to be .224.
PP1V2_S3 .087 supposed to be .223.
PP0V6_S0_DDRVTT .262 supposed to be .136.
I am going to try and swap out this chip U7800 if I have a donor somewhere.
My reference: TT10275
Board History: Tons of dust, very dirty, especially around U4200.
PP1V8 I get nothing.
PPBUS_PMIC I get the 12.59v
PP5V_PMICLDO: 0v
PP3V3_S5: 3.3v
PP3V3_PMICLDO: 0v
P1V2_SW_SNUB: 0v
U7800 problem?
Looks like it's the processor.
What is weird is I took up U5700 from the board and plugged the USB-C meter and I saw the voltage go to the regular 5.1v, but when using the IR camera, Q5840 got real hot, so I lifted this too, then Q5820 I noticed was getting quite hot. I put down some alcohol in...
Yes, I saw the LDO's at the bottom of page 37 for chip U7700, but when I click on PP1V2_S2_SPMU for example, it goes no where as opposed when I click on PP3V8_AON_SPMU, it highlights all the capacitors around U7700. It doesn't appear openboard.org has this data either when I looked at a few...
My reference only: TT10141
Board history: Coffee spill. Most damage was around UP800, U5000, and U9300.
Issue: Not powering up, USB-C meter shows 4.92v, drawing .95 amps.
Work performed: Replaced U5200, Q5820, R5215, R5216, CW194, CW187. I removed and placed back down UP800, U9300, Q5240...
My reference only: TT10189
Problem: liquid damage, does not turn on even though USBC meter shows 20v.
Work done so far: C9589 had a short and was replaced. CHGR_BGATE has 12v but is unstable, it drops to 4v then back up to 12v. I have already replaced U7000, I also removed all the capacitors on...
