Hi, somebody wants to sell me a macbook pro a1286 from 2011 for 505$ (cosmetic conditions are good) but it has the issue of the no image on screen.
Is it worth? can I go to apple to fix it for free with the program?
Ok I have solved this board, it was all because a 470 resistor that you can see in the pictures and the memory, I applied flux under the memory, then put heat (430C) from distance couple of minutes and now it is working perfect, I've been testing it for a few days and works great!!
Thank you all.

is perfect for me thanks
But I´d like to know the temperature, 400-430 is it too much?
I know you control the temperature moving the nozzle (sorry about my english) but I´d like to know when you approach to the smc

Q: ok thanks, reflow here doesn't work? ( I answer to myself)
A: No, I already did, it gave me green light for a few seconds,also I have almost all power rails, but it is like BGA reballing or reflow...is BS the chip is gone.
Waiting for a new one.
I have donors board but no smc stencils anyway...
I´ll try to explain myself better:
NO GREEN LIGHT
Charger 60W

PPBUS_G3H: (F7040) 12,12V
CHGR_ACIN: (U700 PIN3) 4V
CHGR_ACOK: (u7000 pin 14) 0,607 fluctuating
So it is not sending nothing?
Why is that?
Can anybody help me please? Im stuck
I replaced u6900 too and some bad caps, I don't have green light yet
PPBUS_G3H: 12,5V
PP3V42_G3H: 3,4V
SMC_BC_ACOK: 2v fluctuating (u6901 pin 1 and 2)

ADAPTER SENSE: 3,46V
SYS_ONEWIRE: 3,46V
SMC_RESET_L: 3:46V

So probably is the SMC isn't it?

How to Stop Tremors: Home Remedies
A tremor can be defined as a shaking movement. It mainly manifests through your arms although it can affect other parts of the body such as the voice box and the head. They can happen to anyone even though they are common among the elderly. We all have some...
I agree, as a shop they are gonna try to fix the boards themselves to avoid paying you then if they fuck the board they can say that you fucked it up so...win/win for them.
For that kind of people Karma and fuck them all :)
