Gaming Nintendo DS Lite Hardware Issues

[Skelletonike]

Well, I gave my DS Lite to my cousin when I got my 3DS, however, something seemed to have happened to the DS because whenever the L button is pressed (while the button is inserted), it sometimes turns the console off, I have opened my DS now, to check out what's the issue and so far, everything (the cables and chips) seem in place and none of them are damaged, I will post pictures later on since I might be missing something. The thing is, the L button works fine while the button is removed, anyway, anyone has any ideas of what might be the cause?

Maybe the plastic of the button is scraping against something.

Well, I took some pictures, sorry about the quality, it's kinda dark here since it's already night time and I couldn't find my digital camera so I had to take these pics with a phone:

Edit: Managed to paste the pics, stupid imageshack, but they're too big so they might stretch your page. xP


Edit 2: Just tried turning it on, and sometimes, the console just shuts off a while after turning on, even without it's shell...

I tried checking those cables, but they seem intact, I took new pics today with a better lighting and resolution, both the white and black cable that are highlighted in that picture are connected properly and aren't damaged in any way (well, that I can see at least), all pins are in place that I can see... I really dunno what might be causing this issue. *Pissed at himself*

Found what the problem was, thanks for the help Sora, you can close this thread now mods. *Goes off to look for a ribbon cable for the DS Lite*
