My Walkman has a cracked shell and I am wondering it any sites are selling replacement housing shells.

Hello there. My Nintendo DSi has not been turning on for the past five years (July 2010) and I need some advice in order to turn it back on. My laundry had been placed into a washing machine with the DSi in my pants pocket. When I took the DSi out of the machine I tried drying it in white rice. After a few days of drying, I press the power button but nothing but a flicker of the red power light. No matter how much I charge the handheld, it still won't budge turning on. Nowadays, I still struggle to to turn on my DSi but has different affects of turning on. Instead of the red flicking power light, the blue power light comes on with the a white screen (mostly). Sometimes my DSi goes to the home menu but will not run any applications, probably due to water damage. It always brings up a black screen with a message on the bottom screen, stating that an error occurred and that I needed to refer to the manual. If any of you guys know what is wrong with my DSi and knows how to fix it, tell me. I cannot seem to...
