Thank you for the advice - I have two screens. One known good - brand new screen aftermarket (which worked up perfectly until I did what I did) and one OEM screen which had lines showing up on the screen - still partially functional. Both of these screens worked. Now both do not get an image...

Both are present - 3V3_SW_LCD is reading 3.29 to 3.3V and 5V_SW_LCD is reading slightly higher at 5.14V For LPPD_INT_HPD voltage; RP611 im getting 0V.

Hello again, update: With the screen connected and power via cable, up710 pin14 is also accessible through via tb462. - I got 1.78 to 1.8 V up710 pin 4 at ta277 - i got 1.8V up710 pin 11 i got about 1.79V These are two vias that werent on the schematic i have - as in connected to the POI. am...

Thank you for your response. I will do the needful and update you. As for responding - I see two buttons. One reply directly to the recent update by you. And another by the box where you type. This would be confusing to any new user on your forum. It is not with the intent to quote an entire...

For grounded pins - it should be 0V - i understand your point. About earlier, i understand my question was a little stupid as I actually misread what you wrote - the way I work is methodical. Even if I know the expected output I have the tendency to confirm it anyways. Since I don’t run a repair...

Thank you for your response. will check the pins 2, 4, 6, 24, 26, 45, 46 in diode mode aswell. For pins 8,18,28 and 38 and pins 4,11,14 i check for voltages with it turned on as in plugged in with the power button pressed? If possible please tell me if the expected values as listed above are...

JP600_PIN_32 Default d 0.595 Red to ground: 0.581 JP600_PIN_34 Default d 0.595 Red to ground 0.583 JP600_PIN_36 Default d 0.587 Red to ground 0.583 Just updating as i get the expected values by testing by polarity (as per instructions red to ground - black to component)

At UP710 @4 - 0.549 @11 - 1.156 (red to ground - 0.556) @14 - (unable to check as test point is underneath up700 - Please confirm if i am to remove component) thanks again i appreciate it.

Hi upon testing JP600 with components connected I observed the following: EXPECTED/Theoretical TESTED JP600_PIN_10 Default d 0.332 0.34 JP600_PIN_12 Default d 0.331 0.339 JP600_PIN_14 Default d 0.365 0.365 JP600_PIN_16 Default d 0.368 0.364 JP600_PIN_18 Default d 0.001 0...

Hi, thanks for the warm welcome and thank you for your response. I did indeed disconnect the cable when it was powered on with the battery connected. I feel extremely stupid about this. I do think it is a 820 - 02020. It’s a 2020 M1 MacBook Pro 13 16/256GB EDITED: confirmed it is a 820 -02020 A...

EDITED: Hello! I’m new to this forum — and I did something pretty stupid. I picked up a used top case and an aftermarket display, then swapped over the logic board and Touch ID. Everything worked fine until what I did next. I got a popup to “complete the service,” so I tried to finish the...
