Both screens backlight, but do not display. Why?
Blue powerlight. Volume. I can even get it to go to the 3DS firmware update menu. But I can't see anything on either screen.
After re-assembling my 3DS XL, we booted up the system to see the bottom screen turn on and the touchscreen function but got no display for the top screen. With some digging, we concluded it was the top screen LCD ribbon connector and went back to reconnect it. Indeed, the connector was crooked and we fixed it soundly.
Upon our second re-assembly, we can no longer get either screen to display anything. I have tried a great number of things, such as:
Making sure the wifi card is connected
Reseating the bottom LCD ribbon connector (I'm not sure if this is in all the way.)
Reseating the thinner ribbon connector next to the bottom LCD ribbon connector (The clasp on this connector was broken. However, it stays in like a champ and I'm confident this is not the problem)
Any help would be greatly appreciated! I can provide pictures of whatever is needed.
