Hey Andres,

puede ser que tengas el rail de voltaje bajo cortocircuitado a tierra.

hay un diodo cerca del pin numero 4 que has marcado en la primera imagen, you comprobaria que ese diodo estubiera bien con un multimetro

si cambiaste pi3usb tambien chequearia que no hay ninguno de los railes que llevan 1.8v y 3v a tierra.

nos podrias decir los voltajes que mides en los pines del conector del ventilador?

te dejo adjunto una guia que he creado despues de juntar montones de cosas de los foros, igual encuentras algo que te ayude alli

buena suerte !!!! y saludos para Chile!

oohh muchas gracias.
el primer punto que comentas es cierto, el pin 4 entraga el volaje por lo que tengo entendido, puede ser ese diodo lo he medido pero como es tan chico que cuesta.
segun he medido en otras switch el voltaje debe ser 3.8 cuando el sensor detecta alta temperatura. tambien he medido el sensor y esta bueno segun lo que pude averiguar.
observa tus apuntes gracias

English?

pin 2 and 4 are in short, image 1 reference
i replace integrate 2 in the second image but still in short pin 2 and 4
with or without integrated short still

bettwe pin 1 and 4 are 0.8 volts, they have 3.8 in normal work

I have the same problem with a switch I have, The fan just won't work on it and it overheats, Have you tried removing the
diode and see if the short goes away ? I may just jumper my fan to 5v and ground on the board if I can't find a way to get rid of the short, it will be on all the time but at least it won't overheat and shut down.

what diode my friend
is nearly conector of the fan?

 

[gargoyle67]

Yes at the bottom marked, although it looks like you board doesn't have one. I've test mine and it shows ground both sides. My board is a patched model.

ok, i have the same model, can remember this piece in my board have two extreme to the ground. i try tomorrow, i dont have replace for this piece , i have 2 more board but they no have this piece.
i can understand very fine but u have the same problem and could you achieve fan work?

 

[gargoyle67]

I'm going to remove the diode later and see if it removes the short, it should work fine without the diode as it just stops voltage travelling in the wrong direction from what I've read. I had a 8tb hard drive that wouldn't work untill I removed a shorted diode. If it still won't work I'm going to jumper 5v from a cap directly to the fan, not ideal but at least the fan will work.....

 

[gargoyle67]

confirmed removed shorted diode and the short on the pin went away fan started working as it should now ! yay =)

i removed diode today, and short is gone
i dont have time for more probes but i think is fixed thanks

 

[gargoyle67]

Should work, good job !

tratare de explicarlo en español debido a que no manejo bien el ingles.
bueno, en la imagen 1 pueden ver el ventilador trabajando, en el pasado dañe el conector FPC de el LCD pero es facilmente reparable.

en un principio no me basto con solo remover el diodo, tuve que resoldar unos pines los cuales son del ic del ventilador al parecer. segunda imagen

bueno desde ya muchas gracias por su ayuda. espero le sirva a mas gente .

How did you remove the diode? This is completely new to me. Can I use the really small tweezers to take it off?

No, it will need to be desoldered, and if this is completely new to you, I would strongly advise against attempting this yourself.

Your best bet would be to try and find someone local to you that can do it for you.
