It may be time to give up on this one but I’m seeing if you have any ideas. I swapped the other CD3217, now all ports read 5V 0.3A steady, no fan spin, and DFU still doesn’t work. I swapped it twice in case I messed up or something the first time. Please lmk if you have ideas for something to...

Will do, I just ordered more of the chips because I’m out. With Labor Day it may take a little extra time, and I’ll try the DFU method you provided and update you after. Thanks for the advice.

Please help

Intake Condition Liquid damage (customer spill). On bench: most ports negotiated 5 V ~0.30 A, one port showed amp “bouncing” (unstable current). Timeline / What I Did Ultrasonic clean (proper dry-out). → Behavior changed to boot-then-die loop: negotiates 20 V, fans spin for a few seconds till...

FUN!!! Last question about this depending on your answer, if I was to purchase BY-T200 (unless there's something better) and Blank T2 ROM Chip would I be likely to move forward? (I stumbled on some videos in the past when looking up firmware chip programming stuff closer to when I started). If...

And is testing on the two components and the corresponding test pad, like, I put the multimeter in continuity mode and checked if it beeps to ground with the board disconnected from power, is this the proper way to check if that is shorted? It beeps on all of that.

I try to do as much as I can with the direction you point me in to make the best use of your knowledge and learn as much as I can; I wish I knew more to make it easier for you to help me but I will definitely get there, I’ve learned so much since May this year. Thank you. I can’t wait to spend...

Aite, what I could get my hands on fastest: •Proper known good trackpad flex from same model •1 2019 MacBook Air trackpad •1 2020 MacBook Air trackpad board/flex and corresponding board (same year but from the M1 series) I tried every combination of the parts above; Nothing changed for better...

Ty, I successfully disconnected the WebCam (doubt it’s relevant, I also checked to make sure that it works prior to disconnecting it and it did). Still very slow, still the same reading on HW sensors. Still only able to boot into internal (not in safe mode) I would like to correct an answer I...

So, I am very much still in the learning stage; I did some googling and I spoke to the friend I have that is a little more advanced than I am. I’m not exactly sure what the T-CON board is I feel like this is it from what I gather. I tried a cracked display to see if it would change anything...

I ordered a new touchpad keyboard board I don’t think I have one, I’ll go through the rubbish at home to see if I’m overlooking anything; is there anyway that I can test if it is that without waiting for the new one, it arrives at the end of October and I didn’t have the option to make it faster...

Sorry, I chose the small file for the photo and I guess it blurred “heatpipe outgoing air 128° C” it doesn’t let me start in diagnostic mode, The fans seem to be spinning at a normal speed, I don’t have a good trackpad board on hand, this one “looks” to be fine I also had to ultrasonic clean...

Came in, no power, liquid damage. Ultrasonic cleaning allowed me to power on and boot very very slowly. Keyboard back light area looked a bit rusty but was functioning I removed funky looking caps just to clean up and re-solder, continued working but computers very slow, I imagine it’s a sensor...

It’s very likely but hard to tell since it wasn’t booting successfully to anything but it was restarting itself and trying to boot so I think no I think it was not doing it before but I’m not absolutely positive.
