I don't have another board to measure against but I plugged in another display assembly I know worked in the past and that didn't work. This time i also saw ESC light appear on the touchbar

I booted in DFU mode. Initially I tried to revive firmware but I never saw anything appear on the screen like I have in the past then it froze so I cancelled it and restored the firmware. Again I didn't see anything appear on the screen then this image appeared on the screen that said...

Yes I have a flashing link LED and yes the caps lock key reacts everytime.

I get a light on my usb stick I plug in but there is no image or anything from an external tv plugged in.

I couldnt find the ONOFF lines for this board because the board view I have is on a pdf file. I checked for voltage on PM_RSMRST_L and PM_PWRBTN_L on R1800 and R1802 and got 0v on both.

From what I saw there was no voltage or pulsing on neither PM_SLP_S4_L or PM_SLP_S3_L.

That was with the battery in. Wout the battery it goes to 0.05A for a couple seconds then stays at 0A. I checked for voltages on PP1v2_S3, PP1v8_S5 and PP3v3_S5 and they had 0v. L7690(PP3v3_G3H) has 3.3v on it and L7030

Okay I injected voltage and found that CB300 was getting really hot. I replaced that and now it turns on the trackpad clicks, I hear the apple sound that happens when you plug your charger in and the caps lock button turns green when pressed. The only thing is nothing appears on the screen...

I have this board that was sent in for water damage. When I plugged it in the trackpad would click and the ammeter read 19.8v and 0.55A The only components that looked like they had any kind of liquid damage were C8412 , C7660 and Q7660. I replaced C7660 and C8412 and put the board in the...

In diode mode to ground here are all the 3v3 LDO measurements. CB308 - 0.487v CB408 - 0.486v C3108 - 0.484v C3208 - 0.487v 1v8 LDO CB305 - .048v CB306 - .051v C3205 - 0.478v C3206 - 0.514v C3105 - 0.475v C3106 - 0.51v CB405 - 0.481 CB406 - 0.515 1v1 LDO CB304 - .498v CB404 - .504v C3104 - .498v...

I have this board that doesn't look to have any liquid damage and is stuck at 5v and 0.21amps on all 4 ports. There isn't any boot loop just a steady 5v. I was getting 1.4v on PP3v3_G3H and so far I have replaced U6903, R6910-13, C6910/11/13/15/16 and D6902 . I still get the same voltage but I...

Anyone have experience with these?

Hi, I have this A1706 that has some damage to the corners of the topcase and may need to be replaced. I found some top cases that have only a keyboard so I would need to transfer over the touchbar and everything else. I was wondering how difficult it is to remove the touchbar from the original...

Okay I figured out that C7505 was issue had some solder connecting it to the probe point in front of it. I figured they were connected so I didn't bother separating the solder but it is all fixed now. Thanks guys!
