I replaced the cracked screen on my 2DS, and it turned on once and worked fine, but now the light turns on for a few seconds, the speaker pops, and it turns off. The screen never turns on. I've been trying to fix this for a day now, I've tried a different battery, I've reseated the wifi card, I've checked every ribbon cable so many times I lost count, I've cleaned the ribbons with alcohol, I've even tried removing the heat sync on the off chance that it's shorting something. Absolutely nothing works. Any ideas? And no, I can't send it to Nintendo, I don't have a warranty.
