I tried finding schematics or boardviews for this one but was unable to source any. I have a blown component that matches the ones next to it labeled "1827 S6D" Next to that was a shorted capacitor that I removed but don't know the value of. Any help is appreciated. Image of board where...

I'll check 1V8_G3S tomorrow. Sorry I don't know what ssd rails are significant as when I lookup "SSD" I'm software there are numerous SSD rails and I didn't know which ones you'd want to know and which weren't significant.

PP5V_G3S - 5.141V PP3V3_G3S - 3.344V PP2V5_NAND_SSD0 - 2.519V Those are my voltages while it's connected to the other Mac still post revive. Attached is what my main mac displays.

So Revive worked or so it says. I get the Lock icon after revive but I still have no display.

Played around more and got it into DFU. Attempting to revive now.

Attempted external switch with no change. After powering off the machine with PMU_ONOFF_L amperage drops to 0. Then pressing the DFU button for 3-5 seconds does nothing. I did measure to make the sure button press is connecting the 2 points and continuity shows it is. 0V on DFU_STATUS.

Here is the T2 under thermal imaging as it's plugged in. Draws 0.12-0.23 amps then drops to 0.040a

MacBook A2251 Brought in because the customer was not getting image for their machine anymore. Could hear sounds but no video. Another tech in my shop attempted a screen replacement. After the replacement the device no longer gives any power up sound or display still. Current State: Just the...

Have a MacBook A2141 that was brought in for not charging/no power on 820-01700 Looking at the board there were some signs of liquid damaged around U9080 - TPS62180 This was the only noticeable area, after ultrasonic cleaning the board didn't measure short in this area. All resistances...

Yes I played around with different things for 30 minutes without getting anywhere. I did take note it can be difficult but no matter what the machine was either off, or the CPU was heating up. I wasn't getting anywhere with it. Even attempted redoing the switch wires.

After forcing it to power off with the switch. It is still refusing to enter DFU mode. It just restarts at 0a and replicates what it's been doing of getting up to around 0.5a current draw and staying there. Regardless if I hold the DFU Force or not. I double checked soldering connections and all...

And that hot to the touch is through the cooler.

I double checked my soldering. I don't even get a response from the power button when holding it. The machine just stays at around 0.5A and doesn't drop. CPU just continues to get hot and fan tries to keep up but doesn't. After 20 seconds the CPU is very hot to the touch.

DFU doesn't work evening using a switch. Caps Lock has no reaction or light.

Have a Macbook A2179 that came in for not powering on properly. Customer stated it just stopped working and doing this. System doesn't appear to have any signs of liquid damage that can be noticed. With the battery disconnected, once plugged into power it boosts to 20V and draws around...

Okay that's what I suspected. Unfortunate :(

Working on a Macbook board that came in for no power. Stuck at 5V on USB-C Meter. No previous repairs or work done too the machine. Looking under the microscope I found PPBUS_G3H was shorted. Injected 1V @ 2A and noticed U9080 (ELC180) getting hot. Removed the IC PPBUS_G3H reads in the...

Known good BIOS was tested with no change in function/condition

I apologize. I wasn't aware of that fact at the time of posting. Will make sure all information is known next time.

Will try known good BIOS. Visual inspection shows no signs of mechanical damage. After observing the whole board under the microscope I was unable to see any damage to any components, even by screw holes. The machine worked for about a month with the new battery prior to this issue. I feel it...
