ok, good to know for the fan.
No caps lock, no USB activity
PLT_RESET_L = 0.0V
U1950 Pin 3 = 0
U1950 Pin 7 = 0
C1950 1 = 3.42
After 4 min, fan start to spin.
Hi,
A1502, no liquid, stop working suddenly. Yesterday, I've plugged magesafe, light ok, charging ok but not turning on, CPU warm and at some point fan was spining but nothin on screen, even with external light to check backlight issue.. no chemie.
Today, I took board out, L7320&7310 are short...
Hello,
Got this Macbook Air. Board is clean. When connected I get green and orange led, fan doesn't spin. SMC looks ok.
I am suspecting C7500 but before removing anything i want to make sure.
C7500 Pin1 = Diode mode = 0
C7500 Pin2 = Diode mode = 0
U 7501
23 = 0.0 V
22 = 0.00 V
12 = 3.4V
13...
Thanks.
F7700 is good.
without LCD
D7701 Diode mode to ground.
Pin1 =.389
Pin2 =.604
with LCD (almost same)
Pin1 =.388
Pin2 =.604
XW7720 is a bridge or that's just a piece of copper, I don't get what component is it (pics attached.. there no component)
pics of U7701, it looks ok to me.
Hi,
I got this A1466, got drops of milk, was sill working for month and now stopped. I can see trace of yaourt neard LCD connector, on diode, bigcoil and the two caps.
When connected to power, magsafe get green, then orange, fan start to spin for 3 seconds, I hear Chemie... and reboot, same...
Thank you, was short. I don't see the value of that resistor. How can I know what resistor I can take to replace it ?
btw I've read another poste to check if T2 is still ok, R6401 (PIN1) SPKRAMP_RESET_L, diode mode to GND =0.351, that mean T2 should be ok.
Thank you for all your help. So I gave up and reassembled the Mac today. I did a little test before preparing the package. I see it's taking from 0.11 to 1.06 amp when I press the power button. So I tried to put it in DFU, that works. I tried "revive" but it failed with "the operation couldn't...
