The sound quit working, what do I do?

Nintendo DSi XL Speakers Replacement

I have replaced the top screen in my childrens ds lite (similar job) several times and have desoldered and resoldered the speakers... It's pretty simple, you don't need anything fancy, just a soldering iron (40w makes the job quicker but you can use lower ) flux, solder, desoldering braid and a steady hand. It may be that you don't need to replace the speakers... It may be a loose solder joint so I'd check first before ordering. You can buy the parts/tools on here.. They are linked on the guide or you can source your own. Good luck
