i have found the short beneath some layer, now bklt_boost resistance is around 1.7k ohm, i use caps thats the same size for the caps i removed before, is that okay ? or should i use same specification? diode mode 0.293
if i pwoer it on without screen, its normal, but when i power it on with screen, i smell some burn but idoesnt found anything blown..
l9100 is 0.5 ohm resistance, is that okay ?

r9708 is shorted. is there any part from macbook donor i can use ? i can't seem to find any..

 

[Yoel Ren]

but that resistor is connected to ground, and the resistance is 0.1 ohm.. correct me if im wrong
iassume pp12v_lcd is the output ? resistance to ground is about 2k ohm with screen connected.
any replacement for this r9708 ? cause its blown..

 

[Yoel Ren]

when i see 0.1 ohm resistance to ground on r9708, i then inject voltage there which blown r9708

I cannot beleave that!!!
Good luck to find replacement resistor now.

I cannot help if do not even read me...

 

[Yoel Ren]

im sorry.. i read every your message carefully.. english is not my native language so ims orry if i miss something.
yes i read that resistor is 50mili ohm, but there's no resistor package with that size from donor board, is it okay if i use smaller resistor with jumper wire ?

 

[Yoel Ren]

wait.. even jumper wire is at least 0.1 ohm in resistance..

 

[2informaticos]

You had 0.05 ohm (50 miliohm) resistance.
What reading did you expect to get, apart of pure short???

 

[Yoel Ren]

i have replaced the r9708
I have pp12v going
I can seeimage by flashing the lcd, so its no backlight problem to be exact..
L9100 is fine
f9700 is fine
I have tried replacing q9700 too
diode mode d9700 with another board, similar result.. any idea ?

 

[Yoel Ren]

I have another board so I already eliminate lcd and display cable problem
