First check continuity between the spot in the red circle, and the orange dot to the right of it. Press the button and make sure the value goes close to 0ohms when pressed. Just becasue those buttons 'click' when pressed does not mean they are good.

If the button tests good, then solder a jumper wire and connect the 2 Orange spots. Also make sure the solder joint in the Red circle is good making connection to that trace there.

Screwing up is one of the best learning tools, so long as the only thing you're not learning is how to screw up.

Hi

There is continuity between the red circle and the orange dot on the right while I press the button I made the jumper between the two orange dots (as you can see from the photo) but it still doesn't work

thank you very much for helping

Follow the trace from the red circled spot and make sure it's not damaged anywhere.

Pic isn't that great, trace looks open here though.
