Hi, the flax cable of the Touchid button broke… if I want to fix this which is the part that I should keep so the touch id function continue to work? The button or the flex cable side where are some capacitors.

thank you

hmmmm is a there a procedure to check if it is a CPU or GPU problem?

No history it came like that "its not turning on anymore, fans spin but nothing comes on the screen" no signs of water nothing.. PLT_RST_L : 3.3V

Hi, I got the macbook pro 2016 820-00281-A that doesnt boot, I checked almost all rails and they are present, didnt find any short and the amp sequence looks ok but doesnt boot. trackpad enabled, keyboard shift key light not present, when I insert a usb stick its light turns on for a sec. but...

yes looks like :(

connector removed, still the same

CPU voltages the same 0.844V but now the amperage increased to 0.60-0.64A before DFU was around 0.50-0.52A

j5110 not replaced, but is not doing short or anything as the pin´s readings are all good. not easy to find that connector. will check CPu voltage

DFU didnt work, I did a restore it went thru and appeared a lockpad icon but still no boot, no green light on shift key, cpu still gets warm...

going to try DFU now

sorry I understod wrong, all pins measures: 3: 0.506 4: OL 5: 0.506 6: 0.456 9: 0.504 10: 0.457 11: 0.505 12: 0.455 15: 0.517 17: 0.516 18: 0.543 20: 0.543 21: 0.465 22: 0.543 23: 0.465 and those are very similar to a working board

Thank you for your reply. at the beginning very fast to 0.5*V then to 0.84V and stays there... on a good board J5110 line diode mode: 0.551 bad board: 0.539

Hi, I got a Macbook A2159 Board 820-01598-A that is not booting, possible water damage but Im not sure... the connector J5110 has 3 pins burned: 18, 20, 22 the line of those pins is PP3V3_G3HSW_DFR, the line still has 3.3V The board is out it consumes 20V and 0.50A in the boot process it go a...

tried all and nothing worked, I think I will just mark it as no fix... Thank you for your help

Desoldering the chip I lost the 20ohm resistor on the left side R4773 (SPI_SOCROM_MISO Line), I dont have a 20ohm resistor I got a 22ohm same specs, can I use it?

tried to do DFU many times, the step 4 takes a longtime after that it goes to the lockpad icon with a warning at the botton saying the system has not booted or something like that and the system needs to be repaired if I try to repair it fails saying that in this state it cannot be repaired so I...

Hmmmm sounds really easy.... One more thing, I noticed that L7030 is 1.9Mohm / 0.455 on diode mode, isnt that kind of low?

Do you know which are the equivalent to the lines: LPC_FRAME_L, LPC_CLK24M_SMC in these T2 machines? I want to try the troubleshooting method that checks the wave form on those lines, I want to check if it is the CPU

it goes streight from 0v to 0.844 when USB-C starts pulling 0.4x Amps then stays in 0.844-0.845 until power cycle then starts over. Something makes it reboot...
