Karaoke CDG Display

Hi Everyone. I’m new to the forum…Lovin it but don’t really know what i’m doing.
I have a KAM kdj600 cdg and i have just bought some discs for it. The mixer has a yellow wire comming out of the back into a scart converster that then goes into the scart port on the back of my 14" TV.
When the cs starts it takes ages to begin to play but the title of the song doesn’t display correctly on the tv. I don’t know what is wrong. Is it the Mixer, the tv, the cables or the discs etc. Please help!!
