Green Screen :(

This is quite annoying. I have one of those special doo-da ps2 cables which are meant to elimate green screens etc. It has a switch on it where if I put the switch one way the colour is fine (but NTSC games are B&W) and when I switch it the other way both PAL & NTSC games are green screened (before it was all colour).

This has only started happening recently and I have had the ps2 and cable for nearly two years now :(

Would it be the PS2 messing up or am I going to have to go and do an argos scam and get the cable replaced?

Dont worry, sorted. My brother had obviously been messing around with the settings and selected component out rather than RGB. DOh
