So i bought an ac adapter online, because my previous one stopped working, but this new ac adapter i bought ended up having a red led light. When i touch the power button it turns on but 2 seconds later it turns off. I was wondering if it could be a problem with the system itself or the ac adapter.

Might I suggest that it is a heating issue… see because if it goes automatically off, the system is telling itself to shut off without warning, to save itself from the system catching on fire. Check the heatsink on the motherboard of the console. Or you might need to replace the cooling fan. And if its a power issue, either replace the ac adapter or power supply. Hope this helps! -Toby
