Hello I had a problem with my o3dsxl upper screen. The console was turning off when with was in full opened position but it was mainly OK when in semi opened position. I purchased an upper screen replacement from aliexpress and but following the online videos and guides I replaced it. Everything in the process went OK but when I turn on there is the blue led power as always but both screens are black except upper screen which gives a kind of backlite and then the motherboard gives a sound of electricity. Also the console does not charge now. I understand that this is a hardware failure but what part? I believe that I connected all the ribbon right. Any idea? Thanks
