Messed up A button and L button/screen?

My DS has some serious problems. The A button is super compressed, and is really hard to press. Probably from playing too much? Not sure if this one is fixable.Also, the L button doesn't work properly sometimes. When I press it, it messes up the top screen. Sometimes it turns the top screen a shade of red, sometimes completely white. But sometimes, it works fine. Any advice? Are these problems fixable?

Have you dropped it, sit on it? Maybe the buttons are so worn out it compressed to the point that it is not clicking/touching/activating anymore. and about the L button, there must be something broken inside that it is touching the back of your screen.My 10c. Have you tried "opening" it and checking/cleaning the buttons? (or taking it to a service center)
