yeah, you've busted the lcd - if it's the bottom one it's a fairly easy replace. If it's the top one it's more tricky so it might be worth selling on ebay and getting another second hand one

yes, you can buy the ports on ebay or other sites easy enough. You need soldering skills to remove the old one and then to replace the new one. It needs good soldering skills, not just your mate with a giant iron. Sell your board as faulty on ebay and buy another one (if there's one available).

hi sounds like your motherboard has blown, this can be repaired but it's pretty tricky to do this - you'd be better off buying a second hand motherboard and replacing it note though that depending on how much water got in there, it may have also waterlogged the screens as well - if that's the case then you'd be better off buying another second hand ds - they're cheap enough on ebay these days hope that helps

hi this is basically because your top screen is faulty and needs to be replaced. You'll probably find that the ribbon of the top screen has kinked and torn over time. The bottom screen still lights up because the ds sends power to both screens but then when it realizes, nothing is getting through to the top one, it switches itself off hope that helps

There are two things here: 1) When the bottom screen was flashing, that was because the top screen was fauly and needed to be replaced. 2) When you removed the wifi board and the screens then went black - this didn't fix the problem with the screens it simply stopped the ds from functioning properly. This is because the BIOS (program that the ds runs) is on the wifi board - so if you take this out, the ds doesn't even try to check if the screens are working - it just sits there like a zombie hope that makes sense
