When plugged in, I get an orange light, like normal. When I hit the power switch, I get a red light next to the orange light. I get the red light whether it’s plugged in or not, which is strange because the red light should turn green when plugged in. And then nothing. The screens remain black, no sound, nothing. I tested the battery in another DS and it works fine, so the battery is ruled out. The power switch still seems to work as it turns the red LED on and off.. Any ideas?
Have you tried taking to battery out?
