DS: my L/R butttons don't work

[turbler]

Is there any way to fix'em. I'm playing tactics A2 so i can't go without them. Thanks to all who could help.
EDIT: I fixed it by randomly pushing the L/R buttons... but thanks anyway to AK and any one else who helped
Edit2: it seems to take longer and longer to fix each time, I'll go check the warranty like AK said.

It's a common problem. Is it under warranty?

Either way, the only options are to send it in to Nintendo or, if it's under warranty, where you purchased it... or get a new one.

Yeah, I used to have this problem with my DS. It was getting real banged up from jangling around in my backpack all the time during school, then the shoulder buttons would only work if I pushed them in specific places. Said places would constantly shift around or just become completely non-existent as the problem continued. Eventually these problems ended, but it wasn't until a couple months after the troubles began. Simply give it some time and it might just fix itself.

That happened to me, and with GBASP, as well. They usually fix on their own after a few days.

My 'L' is broken, but that's all. If I press it hard enough in certain places it works, but.. you know. Still bad. And I need it for PMD, because double-tapping enemies to use set moves is awkward and annoying.
