3ds xl has blue light but screen won't turn on
I've tried everything I could think of or find with this issue. I've taken the battery out, I've tried it with the SD card taken out, I've taken off and put back the wifi card, I feel like I've done everything to try and fix it but nothing has worked, and I have two with the same exact issue.
Is this a good question?
With the console turned on (blue light on) try shining a flashlight at an angle close to the screen and check if there are any images to be seen.
They will be very faint so trying in a darkened room may help to see them.
If you can see images there's a backlight problem but at least it shows that the console has booted up.
