Neo-Geo Forums

I have a NEO GEO MVS MV-1FZ, and it does not exit the green screen, it is in an infinite loop, no matter the game or even no game, it enters the green screen and restarts, and stays infinitely like this, but even without a game is in this loop, does anyone give me a hope please?

It's the same problem as this video.
