The battery is holding a charge. When turned on, the power light lights blue and stays on. Nothing shows on the screen, no flickers or anything. Opening/closing the hinge doesn’t make the screen flicker or show any life signs.
It can be the d pad needs replacing. It’s a cheap part and easy to replace. See the guides on the right.
Take battery out and charger off. Unscrew it. Remove the bottom cover slowly. Be careful of the 2 ribbon cables when removing it, best to start lifting up from the side opposite the card slot. You will see a big black square below the card slot. That’s the wifi card. pry it up (it has a removable socket) and push it back in. Most probably it’s gotten a bump and got slightly disconnected. When disconnected, the dsi will perform the symptoms you describe. It could be something else, but most of the time, It’s this. Wish I helped. Cheers
I had the same problem but I was fiddling with my 3ds today and I found that if I held down the Power Button for about 10 seconds, it turned on again. My situation was that I went out, decided to place it in my bag for a while. However, when I reached home, I found that the 3ds screens were black but the blue light and the other orange light was on. When I charged it, the charging light comes on too. So I figured that maybe I put it in sleep for too long or something.
Just want to say thanks. forums such as this saved me buying my son a new dsi. his problem was the wifi card, now working like new. so thanks to everyone that puts in the time to add suggestions and help others with other wise unsolvable problems.
This fixed my nephew’s as well, loose wifi board, excellent advice, thank you!
I have the same problem and its to much money to give the people to fix it for me when I turn it on the power light Turns on but the WiFi light doesn’t and screens both want turn on pitch black but it charges and I know nothing bout DS plezzzzzz helpppp
IF NONE OF THE ABOVE SOLUTIONS WORK: The microphone (orange/pink cable) may have come loose, or the microphone is broken. I just repaired my DSI which randomly stopped turning on. Blue light but both screens are off. The microphone cable came loose and popped up (It is directly to the wifi card once you pop the back off). I put it back on and it booted first try. It could either be the wifi card (as listed above), or it could be the microphone.
