If it's a resistor you can't short it, it'll either cause a short on the line or provide too much current to some circuit.

Usually a resistor is used as a pull-up or voltage divider. Can you show us its location on schematic?

Hi. The resistor R3142 no this.
Short it? Compatible resistor? What is the valor?

Sorry its this resistor:

It's a 0 ohm resistor used as a jumper. You can jump it

atr89 · 03-22-2017, 08:59

Hi. I checked the components near the connector, and except the resistor that was not (and already jump it) the rest are all okay. I would check the Toch ID IC, is the U4040?
Thanks

Hi,

yes it is.
try carefully to re-flow and update us.

Albelektronik · 03-23-2017, 12:56

Did you got any luck on that?

I am having the same problem on two lcd iphone 6s plus (lcd not original) when replaced touch id does not work

And if You put back the original one what happen?
Touch id is very sensitive part, You have to heat a little bit before get the flex or connector out.

I have not been able to solve it. Also I have another problem! When I connect the FPC of the front camera, it stops responding the touch! Already tested with another spare.

atr89 · 04-17-2017, 17:54

Hi. Does anyone know why when I connect the mic / front cam connector it stops working the touch?

Douglazzz · 04-17-2017, 21:54

I had the same problem on my store! But was the lcd+touch quality.,try an other one,bought in a diferent place . Worked for me,it should work for you.
