broken line on LID_OPEN_RIGHT... reconnected, it now works. Thanks!

No it was some caps on PPDCIN_G3H, PP5V_S4_X_USBC and P3V3TBTT_RAMP However I have another issue. His touchbar display is gone but he told me about that. Touch works however. Problem is, when screen goes to sleep, it won't wake up. If I restart the laptop, same thing, screen stays off but it...

it was caused by an intermittent or partial short. I did remove all the nasty caps remaining and board did boot up fine.

Already have removed all the caps which are not underfilled with the NANDs but value remains the same. More importantly, what can cause the fan to ramp up fast like that with a shutdown next from your experience? (it takes a second to do that) I am going down the rabbit hole on the SSD/NAND but...

Under? They are all under filled. How can this be?

Hi, I have an 820-01041 that is really playing with my nerves. It was liquid damaged on the edge where the air intakes are. Initially I was getting 5V only. The 1.1V LDO line was not coming on. It had a shorted capacitor on the SSD rail. Replaced it and a few others that looked nasty and got it...

I understand that it could be all of these things. Is there a chart of which signal in order we should be looking at to find out where it's hanging? Like for instance, with no S5 rails coming up, what rails should I be checking before that. Any idea please?

It did not make any difference from what I can tell

PP5V_S5_LDO is the only S5 that has voltage. Nothing, not even a pulse on the others. Here are some measurements: PP5V_S5_LDO 5V PM_SLP_S5_L 0V (no short) PP1V05_S5_PCH_VCCDSW 0V (no short) PP1V24_S5_PCH_VCCDPH 0V (no short) PP1V8_S5 0V (no short) PP3V3_S5 0V (no short) PPVPCORE_S5 0V...

It stays high for 3-4s while amperage is climbing. Once drop to 0, this is when PPBUS drops to 12.2V So I have to suspect a short somewhere I guess. Since I am not getting an S5 rail to pulse I was thinking it has to do first with the PMIC/T2 correct? I am not getting the TRIM rails coming out...

Because here is Thailand and there are not much recourse... Also they just mentioned that the board had an underlying problem that came after. Anyhow, he needs data. I did indeed test the board alone. If those SSD voltages come up, stay for a few seconds and then drop (with PPBUS dropping to...

While PPBUS_G3H is a 12.6V I am also getting the following SSD voltages: - PP0V9_SSD0 - 0.9V - PP1V8_SSD0 - 1.8V - PP3V3_G3H_SSD0 3.3V - PP2V7_NAND_SSD0 2.7V EDIT: I have to mention that I can see the NANDs warming up as well as U9000 and U9080 under the thermal cam.

Hi, I got that board for data recovery. Customer went to Apple after he cracked his screen. MacBook was working prior to going to Apple as he said he could use it on an external screen + internal screen was lighting up. Apple did diagnose that both screen and mainboard were dead. Anyhow, Apple...

Spot on! That was it. Thanks! SSD voltage revived and board is now alive. It ended up in recovery mode but I was able to revive it. Data preserved.

I've just tried with Catalina and I am getting the same error code 0x6 I do get the SSD voltage. There are 2 coils on which I can measure 2.5V next to the NANDs Should I try harder to revive/reset the T2 firmware?

I've tried with different Macs all running Big 11.4 and the latest Apple Configurator 2 with no changes on the error code.

I actually was able to put it into DFU mode thanks to the help of the community. However, trying to revive the Mac I am getting the same following error: AMRestoreErrorDomain – 0x6

Hi, I have a 16" MacBook Pro that negotiate 20V and amperage rises up to 1A then back to 0A and does that in a loop. I have tried that motherboard in a different enclosure, known good, and it does exactly the same thing. So I believe it's confirmed to be a board issue. Board is corrosion free...

So there is no USB activity, only power. PPVCCCPU_S0G stays at 0.95V and never drops even after 30s. I've tried a different Bios and same thing. One thing to note is that the board goes to 19.5V and draws 0.5A for a few seconds and then amperage drops to 0 as if there was some kind of reset...

I swear I've made a search first on that rail name to see if anything would show up so I could read that first but nothing. I understand that you must be answering a lot of same things over and over again so I'm sorry about it. I'll answer you shortly about that CPU vcore voltage, USB activity...
