Guys, a guy recently gave me his 3ds for fixing purpose. This guy broke the two l-r flat cables and the upper screen does not work (it has the backlight but does not display anything). The l-r issue can be easily fixed buying new cables (very cheap on chinese sites). What can I do to fix the display? I'm not sure it is broken so I do not want to buy a replace for nothing. As usual, thank you. UPDATE: I disassembled the device and I found that the LCD issue was simply related to the flat cable that was not properly connected, so one problem solved. Now I need to order the l-r flat cables and everything should be fine. Could you advice me on a good site to buy these replacement parts?
