Hello everyone,
I am new into this, sorry to post it here. I want to make this as a pet hobby project, as this mac is not urgent.
I have (Macbook Pro 13inch 2017mid) A1706 820-00923-A
My mac had liquid damage a long time ago, the connector from J8500 is damaged on pin 46 (PP5V_S0_ALSCAM_F), I guess the LCD/display panel is in short circuit, as I saw the connector from the LCD burned as well.
And the resistor L4004 is literally burned.
From what I see from the schematics, it does not affect any other rails, only the connection to the display... -
Hi everyone,
I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.
🛠 Original Issue
The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.
I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.
⚠️ New Problem: One USB-C Port Only Works in One Orientation... -
I HAVE A MACBOOK PRO A2141 820-01700 THIS BOARD IS PP2V5_NAND_SSD1 SHORT TO GROUND THEN I CHECK ONE SIDE U8600 IS SHORT THIS SIDE IS ONLY ONE CHIP U8600 OTHER SIDE
PP2V5_NAND_SSD1 IS OK AND U9100 U9200 U9300 U9400 IS ALSO OK Will removing the U8600 fix the board or will I have to install a new one

Hello.
I have this HP Omen 17-an108nc that show 3long and 2 short/memory error/ led blinks on Caps-lock after capacitor short on 5V line.

any hint? -
Dell E6430 19v line short,
(QAL80 LA-7781P)
19v rail, output side was showing a short (checked after removing CLR), a polar capacitor (PC1074-processor decoupling) in the core section was getting heat, when replaced that cap, the short gone, but when power on the machine, again that cap was heating (even had removed the processor already). so not understanding even no processor attached why this cap was getting shorted again and again
any guidance please.
