I have bought this machine from amazon ,it arrived on friday. I have a phillips 28inch tv . However swirtching the tosh to RGB output the picture is dark and just wachable. On my hitachi tv down stairs the tosh is fine .as was an old sony 305 dvd player with the philips which i gave to my sister. What should i do as i think this may be an incompatibility problem rather than a true fault? Has anyone had the same problem? I do have a philips DVD890 which is fine on both tvs Please help?
