I need help with my Japanese PS2!

Hello everyone! First post on this subreddit!

I have a problem with my Japanese PS2 Slim.

I want to play DDR Supernova on the console, and I have everything plugged in with the adapter the HDMI cable and all the cords.

The problem is that the power button stays red but every time that I press it, the power button stays red and does not turn green.

If a few people can or can't give me advice, thank you if you succeeded and thank you if you tried.

May you all have a great day and God Bless!
