My ds lite has been broke for like 2 years and it is water damaged what should i do?
paul chambers, this is definitely going to be a chore since you may already have plenty of corrosion and may be even permanent damage. I suggest that you no longer try to turn it on or try to charge it. Disassemble it using these guides. Properly clean it first with sterile water and a soft brush. Do not use excessive force so that you do not knock any components of the board. Clean it a couple of times with fresh solution. Then use 90%+ isopropyl alcohol and clean it again a couple of times. This will displace all the water. You can submerge the parts in the alcohol. Always check your board for any missing, burned or otherwise damaged looking components. After that replace the battery, reassemble and re-evaluate for any problems. Hope this helps, good luck.
