Retro Gaming Repair: Nintendo DSi Shoulder-Button

In this video I attempt to repair a shoulder button on a Nintendo DSi that is not retracting after being clicked. The button stays engage which causes problems playing games that use that button. I open the console up and do what I can. *Note* parts of this video had to be re-shot since the first time I opened it I actually worked on the opposite shoulder button. Some things were lost in the process and the edits may not have the best flow.* I hope this helps is you need to fix your DSi shoulder button.
