Ps2 shows red picture?

I wanted to connect my Playstation 2 again when I noticed that it shows the game and everything but like a red filter.

I wanted to ask what could be the reason? It's still going well and blown down or whatever, it never is. The only thing that bothers me is that everything is red.

This may be due to the cable or the respective connections.
I think you have the standard cable with scart adapter in use?

Yes exactly. I got it together with ps2. Think it was around 2005
