So 2 days ago, my DS lite's D-pad stopped responding properly. The Up and Left directions don't get registered unless I hold it really hard for a while. The down and right buttons work fine though. Then there is the age old problem of the L button not working properly... My questions are: 1) If the up and left button still read although with great difficulty, then the problem is not with my motherboard right? If the motherboard is fine, then it should be possible to fix the problem by opening up the ds and seeing if something is lodged in the D-Pad? 2) To fix the D-Pad and L button is soldering required? Or is it just simple stuff like unscrewing the case and lifting things out/replacing it? Thanks for the help.
