Please help identifying 3DS issue!
So, my 3DS has, for many years, had an odd screen brightness powering-off issue.
As a kid, I found the top screen to be very bright, and didn't seem to respond to brightness control, whereas my bottom one could.
If I remember correctly, depending on the hinge position it could also either work or pop and shut off.
So I dropped the brightness to one, and managed to keep it working, irrespective of the hinge position. This left me with a low brightness bottom screen and a high brightness top screen.
Well, after many years, I got the 3DS out of storage and bought it a charger. I was hoping to mod it!
Alas, I discovered the brightness difference and found it annoying.. I very quickly went to turn up the brightness in my settings.
Pop
Turns off.
I try to turn it back on..
Takes a second, then I see the screens show the home menu for a split second before, again, a pop and the device just completely shuts off.
I'd figured that it was a top screen related issue due to how brightness control worked for the bottom screen only. And of course, you naturally realise that if the hinge position affects the device's ability to switch on, that it would indicate a ribbon cable issue.
So, I found a guide and opened her up.
Here's what she looks like currently. I was hoping that simply reseating the screen connector cables would be enough, however it wasn't.
Instead I've completely disassembled it to get a look at those cables that pass through the hinge.
What I found is I think two tears affects two cables, one tear per cable. One that handles the camera, the other is that one that the speakers are soldered onto.
I'd like to ask, do you agree with me? Are those tears sufficient to cause this problem? And are they consistent with the symptoms I mentioned?
I'm guessing the camera module isn't as urgent, but the larger piece that connects to the top screen directly and connects the speakers, I'm guessing is the bigger problem.
Images 2-4 show the larger piece and two pictures of the suspected tear.
Images 5-7 show the camera module and again, two pictures of the suspected tear.
Both suspected tears would have occurred within the hinge.
If you lot agree, I'll just order replacements and hopefully get it fixed myself.
Thank you!
Bonus points if you can tell me the album I've currently got on my record player!
Edit: hope the images are clear enough to see the tears I'm hoping to show. Just realised a red circle may have been more useful!
