So it seems the infamous shoulder button fault is finally upon me. I'm aware of the blowing method but are there any other possible ways to fix it manually? Without the L button I'm screwed in games like Megaman Zero/ZX/ZXA and especially Jam with the Band.
It worked for me when I put my DS Lite all the way back, a full 180 degrees. But, since I have a new DS Lite, a crimson one, I'm not having this problem.
Actually, my DS Top Screen was in fact all the way far when the L button started to malfunction (Reason I do so is because the screen is suffering flickering issues and putting it back abates them). Thanks for the suggestion; however I was able to slightly fix the issue by the blowing method and using the DSPHAT method of using a wet qtip to wipe the contact points. I think if I do it regularly I can prevent the L Button from malfunctioning. Thanks for the help anyway.
