Will not power on

Hello @marekschmidt

This sounds like the battery might need to be replaced. As the model gets older and older as time goes by, the battery on these units will degrade to the point where they will no longer hold a charge. It could also be that the DS might not even take a charge but is showing the charging light. You can replace the battery and this will most likely solve the issue, but while you’re inside the device you can take a look at everything inside of it and confirm that everything inside looks good and clean. You also want to make sure that all connections are properly connected especially if the device had a very hard fall. Hope this helps!
