[Solved] Poor Button Responsiveness

[Pentium]

If you need more high-res shots just ask, I need to get my camera fixed.

Yea can't see anything in them, you need to focus on the A button pad and the via to the left of it and on the back remove that huge solder blob and wire and take a picture of that area where the blob is.

Basically like this (these are your cropped images you posted, can you see any details?):

Nevermind, You know that blob of solder? It turned out to be a cold joint, or didn't stick to the pad.
It works fine now thanks
