​aprendiz dukefawks larossmann can u guys help me?

Is MINI_RESET_CONN_L 3.3v or 0.2v?

 

[dukefawks]

90% of the time it is either a fucked up cable or connector. Inspect closer and try a known good assembly. 13 and 15 are both compatible for testing the airport connector.

larossmann 0.2v in MINI_RESET_CONN and L3404 (PP5_WLAN) is burned. I just replaced, but still don't work.

 

[dukefawks]

That burns when someone plugs the connector on the card inside the LCD the wrong way around. Did L3405 fry again?

 

[menatwork]

Yes, i replaced.

 

[menatwork]

0.2v in MINI_RESET

​dukefawks aprendiz larossmann any advice guys?

 

[dukefawks]

I told you why L3405 burned. So now this issue is probably a dead cable/connector or airport card. Start testing with a know good LCD and check if L3405 was not fried again by the old LCD.

 

[menatwork]

New cable and airport card.
The L3405 burnerd, bc the client plug the wrong way.

 

[dukefawks]

No idea then, probably a bad connector. Measure all the pins to the airport card to confirm.
