R button not working well

:O) so the pencil idea didn't work? surprising :O)

Is the charger actually working? can you borrow one or test yours on anothers DS?

The charging socket may have become loose and requires re soldering or other damage on the mainboard like one of the fuses. Get it to a repair shop

My DS Lite went through the wash one time. Luckily it didn't go through the whole cycle. It didn't work right away, for the next three days actually. But on the third day it did start working. I didn't have any calibration issues on the touch screen, thank god, but the L and R trigger buttons stopped working. Luckily, I only play Pok'emon, so it didn't hinder me too bad. But yeah, just give it time.

When the screen goes white, that is an indication that it is attempting to read the game cartridge, take out which ever one is set to start by default and blow into it, becareful when blowing into the cartridges that your not spitting on them as well. If this does not work, please leave a comment and I'll try to assist you further.

Try another card (original). Are all soldering connections ok?

Seriously, wrap your lips around the button and blow. Make an air tight seal. I know it sounds stupid, I thought so when I read it here http://schlaghund.wordpress.com/2008/03/27/low-tech-ds-lite-lr-button-fix/

It worked for all them, myself included.

Enjoy!

you can align it in the options menu. try holding down the power button too it tends to work for alot of consoles and devices

try cleaning the connectors of the game with a qtip don't use any solvents just a dry qtip.

Maybe it's the game card, sometimes if it's dirty or not insirted propaly it doesn't work or freezes, try gently blowing the dust off or reinsirting it.

try to use rubbing alcohol on a qtip and clean the game connectors and inside the game slot. Or try to blow on it. that usually does the trick
