27 inch wierd problem

[Haywire]

27 inch LG flatscreen (picture tube, not LCD). Picture is in black and white, but menu comes up in full colors (red, yellow, blue), so I dont think its a problem with the color drivers. Tried with both RCA and Coax connection and either way gives me a black and white picture.
Any ideas.......
Thanks

Thanks for that..... I'll have to get it checked or replaced.
The TV is brand new and has never been used. TV sales store plugged it in and it was only black and white. Obviously got a credit for it and gave the TV to me. I've checked for loose plugs and cold solders, And also tried the S-Video. Still nothing, but as I said, Menu has full color. The model is an LG RU-27FC30.

If anyone else has any other ideas, feel free to say so.
Thanks.

Also, has anyone ever had one of these replaced before? How much does it cost (roughly).
Thanks Again.
