What site do you suggest for dsi repair info?

[donut]

Hello -
Bought a dsi at a garage sale last week.
Appears to only charge for a minute (orange lite comes on then off)
I press the power button and the blue light comes on, but no picture/sound.

I did not pay much and the condition is so so ... so I would like to attempt the repair myself...

Any sites anyone might recommend to help?

Thanks in advance.

Sounds like the battery might be dead, maybe a replacement battery will fix it.
