Damn, I hate asking questions. I want to help other people too, but oh well. So, I found my old DS Lite. And I powered it on, it worked, so I decided to play some New Super Mario Bros. and Mario and Luigi: Partners in Time. Literally 2 hours after I finished playing, I decided to play a little bit more. Until, it wouldn't power on. It flashes for a split second, and turns off immediately. I tried to turn it on whilst charging, and still the same result. I let it charge for 4 hours, and even after that, I still got the same problem. After trying to turn it on for another 40 seconds, I noticed one important detail. Every time I turn it on only the bottom screen flashes, the top screen just stays black. And I do know that a DS won't turn on if it can't detect the top screen, but what I want to know is if the top screen is the only thing that can cause this. I do know for a fact that I don't have a burnt fuse, neither is my battery damaged. Is the top screen really the only thing that can cause this? If so, how do I fix this? I've searched on YouTube how to do it, but all I could find was how to replace them. Even if I did find what I want, it'd be outdated, I hope to see an answer that gives me a quicker way to fix this. Oh, and.... I didn't drop the DS, never did.
