the chip was removed from a similar blocked board. Please see if they are interchangeable? The first photo is old. The second is new.

after replacing the video chip of the GPU Radeon, the picture is only in safe mode and it slows down a lot! after replacing, I restored it via DFU without errors! What could be the problem?

CD3215 DEAD

does not turn on! 5V/ 0.240A PPBUS_G3H=12,29V PP3V3_G3H=3.23V PCH_RTC_RESET_L=3V PP3V3_S5=0.003V PCH_PWRBTN_L=0.003V

the fact that bad ssds do not prevent entering dfu is important information! thanks. in this case, the option of a bad t2 remains?

I'm more inclined to think that the problem is in T2! Because I also thought that the problem was in 3217 and replaced all 4 with a fully functional blocked board! That is, neither the original nor the replaced 3217 can work correctly but at the same time have problems with the DFU lines! Or...

I've already tried it, it doesn't work!

all SLPS2R are present and correspond to the values of 1.1/1.8v etc., AWAKE are also all present! T2 is barely warm on the thermal imager

unfortunately no

PPBUS_G3H=12.66V I use the original 96W block and a 100W Bluetty station

and also when connected without a battery, the board starts with 20v/0.320 then immediately the indicator drops to 20v/0.0078

unfortunately no S-UEM2! after replacing UB090 all 4 ports work the same 20v/0.078a without battery and with battery 5v/0.000-0.028a. macbook does not boot

the macbook does not turn on! only the touchpad clicks! not in dfu. caps lock does not light up. the behavior of the usb-c ports is abnormal! with the battery connected, the usb-c ports on the j3300 = 20v / 0.000a both! the ports on the jb500 behave differently; the upper one (closer to the...

why is there no image when replacing the t-con? is it possible to replace the t-con entirely? or do you just need to mess around with the chips? is there a link between the t-con and the display?

de, the display is original. The task is to repair it. The MacBook works fine with another display.

artifacts on the display. I think the problem is most likely in the display itself. But I would like to understand what is broken and what needs to be replaced. What leads to such a problem? What are your steps other than replacing the display?

stuck at 5v/0.000a all 4 sides on JB500 ports stably hanging at 5v/0.000a all 4 sides on J3300 ports cyclic switching on 5v/0.000a no short circuits detected

I apologize, I don't quite understand what you're asking. What should I do or check? USB charges the MacBook and was restored without errors via DFU. Please tell me what exactly I can check for you?

PPVCC_S0_CPU=0,854v PPVCCSA_S0_CPU1.114v PPVCCSA_S0_CPUDDR=1.1v PPVCCGT_S0_CPU=0v PPVCCIO_S0_CPU=0.956v PP1V2_S0SW=1.1v PP1V2_S3=1.1v PP0V6_S0_DDRVTT=0.596v

there is also no image on the external display
