I was repairing my old3ds. I had to change its 3d slider/speaker ribbon cable. Everything went smooth, but when I tried to turn it on to test if it worked it did not turn on. When I press the power button the green light from the 3d slider glows but nothing else happens. Not even the charging lights turn on.
I also have to mention that I did not solder the speakers to the ribbon cable. Could that be where the problem is?
