Good Saturday everyone, I have exact same board with seemingly same issue. No internal video nor backlight, boots, chimes, loads into OSX. External video works fine. Tried different LCD cables and different LCDs. LCD_PWR_EN = 0.0V Did anyone figure this one out yet?

Replaced the main audio chip (U6200) and speaker sound has returned!

Greetings, I have this board that has no output from the speakers, however it detects the output device, as well as plays from headphone jack, and recognizes mic input. It is switching back and forth without issues to speakers/headphones when unplugging the jack. Tried replacement speakers - no...

You're right, I borrowed the 96W just today, and it turned on. However battery stays at 1% and is not charging. Never seen this on any other semi-new MacBook

Just to clarify, the macbook is in pristine condition, no liquid nor physical damage, barely used

So there seems to be a common issue with brand new A2141 16" MacBooks that were opened only once and then placed into storage for 4-6 months, only to find out later that the battery is completely dead and the only fix is to RMA or replace the battery. Some people claim to have received their...

Resistance to ground is 5-30Ω on all the CPU coils and 62Ω at L7702. The board is no longer bootlooping after failed DFU attempts

Hey there :) I got this board with no liquid spill or any other signs, no knocked off components. Initially it used to start with 20v 150-300mA, staying for a few seconds and then bootlooping. I tried DFU mode, which it successfully enters, however it failed every single attempt to recover...

https://boards.rossmanngroup.com/threads/820-00923-macbook-pro-touch-bar-question-mark-folder.60375/#post-68248 I'm getting the same issue of non-responsive keyboard as mccafe had. Cannot perform resets nor hold Alt for boot selection. USB key doesn't flash not even once during boot, nor when...

That's great!. With the cap on, all these voltages are on point for the first 2 minutes before the screen boots up: PP1V8_SSD_COLD PP0V9_SSD_FIXED PP1V2_SSD_HOT PP1V8_SSD_HOT PP1V2_SSD_COLD PP0V9_SSD_REG However once the folder icon appears, they all drop to 0v. What could that indicate?

Already did, and it's not working out ;)

Does the cap need to be present for it to function/enable power to the SSD? I believe someone before me has removed it. The connector itself looks intact

Hi, I got a nearly identical issue, question mark folder, keyboard not responding neither for boot selector nor PRAM, same motherboard, same missing voltages. Did you resolve it with U9300 replacement?

J9600 looks clean. Just noticed that PP3V3_S5_SSD is at 0.76v. Does that point to U9300 Piccolo chip?

Do my SSD rails' diode readings give any hints at what to measure next?
