RGB Darkness

Hi. Can anyone out there help me with this one. I have a Philips 28inch t.v. Scart 1 being RGB Which is what i use for my multiregional DVD player and i get fantastic pictures. But the problem is when i try to use it with the Playstation 2 connected with a newly purchased Blaze scart cable i get a very dark picture. I have heard of Philips and Sony equipment not getting on together very well. But this seems a little strange as i get fab resolution but no matter how much i try to lighten the picture its still too dark to play. Now the annoying thing is i have a 10 year old Tatung with rgb scart and the picture is stunning on that but its not what i want to use. So it does rather indicate that Philips and Sony dont mix too well. If anyone out there has had a similar problem and knows of a fix could you please let me know.
Thanks. Mark.
