Hi there, i have 2 DS Lite and wanted to place the working motherboard of one of them into the working shell of the other. I followed the iFixit tutorial, reassembled everything and testes, the DS turned on but the bottom screen was all white. So i disassembled again, resetted the ribbon cable of the bottom one, then retried, only now it just dosen’t do anything, and pluging it in just turns on the orange light for one second and nothing else… any suggestion ? everything should be plugged in correctely, can send pictures Also, i let it sit during the night, when i tried pluggin it in it worked… but the bottom screen was flickering white, so i resetted the ribbon again…. back to the won’t turn on problem…
I think that you either have not completely plugged the ribbon cable in securely enough, or you may have accidentally damaged a part. You may need to check for broken parts and get replacements for any that have been damaged or broken.
