Purchased an original 3DS XL with a "Display issue" Trying to repair
So I purchased another 3DS XL from ebay with a "display issue" it turns on blue light stays on and no backlight sound or screen turning on. It also charges as normal.
Here is what I have done so far based on what I have read online:
- Took it apart and cleaned all contacts and inspected all contacts that are within view - no change
- Re-seated all ribbon cables - no change
- removed mother board and tested it in another known working 3DS XL and the board works fine
- Purchased a new bottom touch screen installed that and still nothing
There is no turning on popping and shutting down. Battery tests at 3.7 V when fully charged
Only thing I can think of is I had a cut right trigger flex cable and replaced it with one from a original 3ds and nothing has changed.
Also there is case damage under above the right trigger so while the hinge still clicks there is a plastic piece which would normally hit against the actual case this plastic piece does come out a little when clicking the hinge to open or close the system. I do not think that has anything to do with it.
Questions:
Would the cable be causing this?
I have tried using a SD card and testing to see if it was soft modded but nothing comes up on the screen in a recovery mode. Have tried recovery mode as well nothing.
I have checked the upper screen by removing the lid and all cables appear to be intact i have also tried:
- Looking in the hinge and no tears or damage to upper ribbon cables.
- Replacing the wifi board with a spare no change in behavior
- testing display ribbons on top LCD (the tiny ones) all seem to show continuity by beeping
I am at a loss, its not worth a lot to send it out to fix because the shell is in rough shape.
Someone suggested it could be the upper LCD or the camera and to remove those one at a time to determine the fault from the board. Can the 3DS XL work without one of the screens attached to the board?

New
And i guess I figured it out. Top screen is bad when you unplug it from the board the 3DS XL powers on so new top screen it is!
