hello guys I have got an 820-01041 with backlight issues. I have replaced the screen cable, and the screen display connector but I still do not have a backlight even though the screen is fully functional, from what I understand, there's no load on the voltage output line, hence the reason for...

Thank you so much for your help

Yes, I tried a USB C cable, but it still 5V, with the same behavior, also when I compared diode mode measurements on the SSD rail with a known working board, it checks out.

Thank you for responding to me. I tried with both battery and charger. When I got it from the client, connecting mag safe 3 has no LED.

Thank you for reaching out, Yes I tried both options : the error I get is 4042

Hello guys Have got a 16 inches M1 Macbook Pro (820-02382) that is stuck in DFU MODE. The Logic board is spotless( very clean ) I went over the board and I couldn't find a short, PPDCIN is 5V PPBUS is 12.32V. PP3V3AON is present, an not sure exactly what method of troubleshooting to follow...

On a side note : Does the machine booting into DFU signifies that all CD3217 are in working conditions? In other words, if I have 5V across but am able to boot the machine into DFU , does this means , my issue isn’t at the CD3217 level ?

Yes : SSD was replaced on one , so what did, was I removed all the SSD chips , but board still boots directly into dfu

good day guys , please I would like to understand this concept, am having two separate machines have started to experience this , one was an A1990 and the other one is an A2141, is this caused by the T2 itself or its PMIC? Please guys , am not looking for a specific solution, I would like to...

Thank you @tcampbell34, not only one Machine? Have had more, and my fellow technicians about 2 shops forwarded me the same issue, one of them just left here not too long ago with the same issue on a 2018, A1990, myself have had it on a MacBook Air and a 16inches and an A1990

I did , I erased the SSD in DFU MODE , but still get the same error message, also other technicians have sent me pictures of the same issues .

Good day guys , I hope you all are doing okay , a big thank you in advance to all of you, for always readily providing support here . So I have started to see a wave of MacBook Pro come through the lab for macOS installation, T2 based macs only , and they are always stuck at a message that...

Good day guys Have got an 820-00163 with no PPBUS voltage , there’s no short on the PPBUS and 2 confirmed isl replacements but same results. Have only got 1.5Von PPBUS. initially, the isl was burnt, so was replaced and also current sensing resistors values were off , so also replaced. The two...

Good day I have a MacBook pro 15 inches A1707 (820-00281) stuck on 5V. One of the ports stays steady on 5V, while the other 3 ports are fluctuating, which I thought suggests the one that is stuck on 5V is the issue, hence the reason why I replaced it 3 times with 3 different known working...

Thank you, this was sorted, I can't exactly say, how, there was no board work: not sure exactly why .

Thank you for getting back : yes I get BL_PWR_EN_R, all signals are exactly the same thing with a working board, the only difference is the backlight output voltage at 14.7V, doesn't that mean the circuit is boosted but no load from the screen?

Good day everyone and happy new year, I have 16 inches 820-02100 with No Backlight. I have used a known good screen and also tested its screen on another device, the screen is not the problem, there is no liquid damage, no oxidation, or anything related, the logic board is clean but with no...

The client collected the device, I did try a different screen but no changes.
