Hey Guys, here is my problem today: The board is clean and everything works great, however, the fans spinning really fast. AHT: 4SNS/1/40000001: ID0R-0.003 Any hint!?

I fixed it! Was C7375! Done

I did and nothing gets hot.

The short is on Pin 2 - PPBUS_G3H

No, just stop working. Actually i have two with the same issue, however, one of just doesnt work PORT 2 and 4.

I'm pretty lost and i need some guide to find out why the USB doesn't work. PM_EN_USB_PWR = 3.30V VBUS PORT 1 TO 4 = 5V

The board is clean, however PPBUS_G3H have a short to ground. I inject V on that rail and nothing gets warm. Can you guys help me on that?

That's is funny! After i put some flux and hit up a little bit U7000 i got this:

U6903 pin 10 = 0

TBA_VDDA = C7075 = 2.5V Could be U7000 ?

PP3V3_G3H Looks ok PPDCIN_G3H = 5.27V

L6900 No Short U6903 - 5V Pin 2

Ppbus_g3h - 0v / no short to ground pp3v3_g3h - 0v smc_bc_acoks - 0v smc_reset_l - 0v

The board is clean, no water damage at all. However, the board is dead. This is my first time working on this new board, i just got the schematics and looks a little bit different. Any hint from where can i start look? FB200 = 5V , however, i was supposed to get 20V, right? Thanks

Did you guys know any good source to buy 10-20 peace the LCD for retina 2013-2015? Thank you

I figure out. The problem was C7715 ( short ) Everything works with the backlight. However, won't hold the battery. Looks like is charging, but when i pull the charger the computer shut down I did the hardware test (D) and NO ISSUES. Lost again!

I can see the question mark, however, i don't have the back light.

U7700 Pin 5-8 = 5V Pin 17 0V Pin 18 5V Chime and Mouse OK
