Hacking Switch not turning on after turning off

[vcintra]

Hello. I restarted my NS this morning and it is not turning on. A blue light pulses for a few seconds, then a green light flashes for a few seconds and turns off on its own, screen keeps black during the process. It was working normally yesterday. A friend told me that I may have been unlucky enough to have the boot 1 and boot 0 files corrupted. Any ideas?

Boot files being corrupted won't cause this. Possible soldering failure. The green flashing seems to suggest an SD loader issue somehow, maybe try a different SD card or try booting without it. Which modchip is this? Harder to help if we don't know.
