I just got a second (flash) back light and then black. Any idea guys?

dukefawks Still the same. Without the cable, works. If i connect, the back light doesn't work.

Nothing. Thats why i cant figure out.

I get stock on this point: The machine works perfectly without Power Audio Board Cable (821-1722). When i connect the cable, i notice the SMC_LID go down for 1.2V and without the cable i get 3.4v The back light work for one second when the power audio cable is plugged. Already replaced DC power...

larossmann looks great. U6100: Pin 1-2-3-5-6-7-8 - 3.30V

Guys, i get this board to fix. The fan spin and everything, but i don't get a chime. Almost the rails is normal, but i get a couple low voltage and none rails bellow. - PP15V_TBT - 14.12V - PP1V05_TBTCIO - 0V - PPVCC_S0_CPU - 1.7V Water damage U8160 area and i fixed. U2940 ( I guess is bad)...

Done! Works fine

dukefawks You are right. I get ppbus!

SMC_ADAPTER_EN - 3.4V SMC_RESET_L - 3.4V SMC_BC_ACOK - 3.4V PP3V3_s5 - 3.3V

Update: Q7130 Get really hot. I just replaced. But nothing change. I have green light 7100 The resistance between pins 17 and 18 - 3.4 ohm 27 and 28 - 20 ohm

Pin 1 and 2 = 3.3V

When i plug the charger, i get PPBUS_G3H (F7140).Pin 1 and 2 i get 3.3v

C7540/82 (lips test) and get a little warm. I removed and short disappeared.

dukefawks Any hint ? I take a look around the CPU and i can't find any bad caps or something like that. I watch again a couple videos from larossmann about CPU short to ground, but no lucky.

So, on PPVCC S0 CPU (C1096) Pin 1 i get 13.8Ω

No, i never tried that.

Yes, i know, but nothing gets warm on ppbus_g3h So, on PPVCC S0 CPU (C1096) Pin 1 i get 13.8Ω

I check and i don't see any sign of liquid in this board. I have short to ground on PPBUS_G3H (F7140 - Pin 2). I plugged the charger and check if i can find some warm component, no luck... So, i inject Voltage on F7140 pin 2 and nothing happen, but i notice the cable i use for inject voltage...

Thank you, master!

larossmann Can u help?
