[SOLVED]Macbook Pro 15 (820-2915) Keyboard issue

[Ciki]

Hi the middle row of keyboard not working letters (asdfghjkl) try new keyboard same ,was some kind of damage where is pin 30 ,but fixed and everything looks ok ,I mean all pins are soldered ok and no damaged

The entire row not working suggests a bad PSOC/Keyboard controller.
They can be awkward to replaced though due to size. Make sure you replace it with one from the correct board as they are programmed.

Keyboard connector or trace. Test all pins of the connector on diode mode. A bad U5701 is very rare.

Replace new U5701 same ,new keyboard connector same ?????

Do you have maybe clear me bios for this one ,maybe its something fucked in bios ,820-2915-a

You can replace the chip and connector, but the first thing you should have checked was a corroded trace.

 

[Ciki]

Already replaced chip and connector all pins are ok

What is between the connector and the chip?.....traces maybe? Diode mode all pins on the connector and one will be wrong.
