Lost color in karaoke monitor..

[mindonstrike]

I'm not an expert but I would guess it to be a problem with:

A) a bad Svideo cable. A broken pin or solder joint. Try switching it with a known good cable.

B) TV itself. You indicated the TV was OK but did you check by plugging something else into it or just switch back to TV programming.

C) Graphics card? If you've got color on your monitor I would guess it's not that unless the svideo jack on the card is faulty.

There was a thread on here several months ago about getting color on a TV but I think they had no color from day one. It might be worth doing a search for though.

My money is on the cable.
Just uneducated guesses here but I hope it helps.
