Minix Neo X7 won't Start

I had this Minix Neo X7 box a while back and it was functioning. I did not turn it on for a couple of years. I know a lot has changed since then, but the box is not turning on now.
I plug it in and get the blue light, on tv. I get the logo MINIX flashing but it doesn't go beyond that. I unplugged several time and pressed the factory reset but nothing changes.

BTW, there are is no sub forum for the neo x7 so I am posting here.

Is there anything else I can try?

I managed to do a factory reset and delete all user data. Now I am on but I guess I need to update my firmware as I seem to be at v4.2.1
I would be thankful if someone can direct me in the right direction
