Hardware GBA SP 101 Doesn't work d-pad correctly.

[Alex4U]

Well, i got my GBA SP some years, is a AGS-101, But today, my d-pad have a problem.
LEFT input is UP
I can't press left, because the console thinks it's "Up"
UP,DOWN, and RIGHT are working perfectly, left is the only problem, i opened today my gb. Sp, i cleaned the D-PAD, and i opened left input, and cleaned (i used Alcohol) and NOPE! SAME.
Aghh... this sp is my favorite, i can't lose it, ;n;
I have motherboards not working of anothers sp's, but I DON'T WANT TO SOLDER LEFT BUTTON. (is REALLY necessary to fix it...? I think... it's yes, right...?) :<
Well, if is REALLY to solder it, i try...
Any knows of this problem? ;n;
