Apparently the customer must have done a t2 restore before they sent it to me cause the drive is empty also in target mode.

Sorry for the mix up. I had a second board with the exact same power issue which was resolved using the correct power brick. This one I only did the revive with hopes of saving the data. With that being said, do you know of a socket reader that i can use to reach each ssd chip after pulling them...

Was hoping the save the customers files but yes I can, which is what I’m probably going to have to do.

Final question, now that i have the mac booted up, the SSD is in an uninitialized state. How do i initialize the ssd. I've tried first aid with no lock? Also T2 revive goes half way and just hangs for a while before it finally runs through and the mac restarts to the question mark folder. The...

Yep that was the final issue. Using the proper brick. Thanks for the assist.

Have this board that got liquid spilled on it. I was able to isolate the short to the T2 chip. Since this would be my first attempt on replacing T2 chip, do i need to replace the SSD's as well?

Apparently all this while I thought I had the 96w or higher but it’s the 87w. Ordered a 140w and will confirm.

Yep. Original charger

Have this logic board that won't power up with MagSafe but will successfully charge a completely drained battery to full and also power up with battery. Once the battery is unplugged it won't power up anymore. it does switch from 5v to 20v but never power up without the battery connected...

Yep that fixed it, Thanks

Have this board, appears have gotten slight liquid spill on J4402 and around the components close to it, as far as D3370. I'm not reading any shorts on any of those components. I do get a short on PP3V3_PMICLDO, about 9ohms. U7800 is clearly blown with a hole on the top of the chip. My...

yes 1V8/3V3_G3S both pulse

L7210 - 1.12 after 15sec. Stays at this and doesn't change

Sorry, I should I’ve also included that theowner had just messaged me that the original issue he had was no image on display. When I got it, it was completely dead until after the repair of the corrosion damage. Regarding usb2 and 3 testing, other than finding a usb 2.0 and 3.0 device to test...

what page is the ssd power rail for this model

Don't think this can be repaired. i remembered during initial inspection, i saw a little liquid spill on J8500. So started checking the pins and EDP_AUXCH_N pin 2 resistance measurement come out at 2.6ohms. Pin 3 reads 58ohms.

PPVCC_NAND_SSD0 - 0.0 The board does look like it had been cleaned in the past but i can't find any corroded components. Yes, i did try DFU and it failed with an error.
