Good cable for plasma TV

New TV - old DVD player. To avoid having to buy a new DVD player, as he has only SCART output, there were two possibilities. Buy a new DVD player or to find a better signal transmission than SCART. When Panasonic TX P42GTW60 Although an adapter was, but I knew by now that a component connection (RED - blue - green) would be better. So this cable hir bought and connected.
Picture on TV black!
In the user manual of the DVD player I found after a long search the solution.
Everything reconnect with SCART - on the TV, you can now the OSD (On Screen Display) on the DVD player to call. Of course, with the remote control of the DVD player.
Adjust then P-scan (instead of RGB) - Under the menu item SETUP - then video.
Then remove SCART again and restore the component connection.
TV again - press on the AV2 - - on the remote control TV picture is there !!!!
