The color is not working. I am being informed to change the motherboard. 42 inch JVC. where can i buy the orignal from?

Please elaborate on the color not working:
1.Is the picture clear just the color shift is off, or is the picture like watching a black&white Tv?
2.If the colors are just faded, non-contrasting, come and go, go into the programming section and reset adjustments to achieve the desired picture.
3. For colors that fade in and out ( come and go ) absent any information as to the source ( cable, antenna, satellite ) check all source connections, disconnect and reconnect while keeping a an eye out for loose, damaged, or dirty/corroded connections.
4. If determined that that the television does have a component fault, I question the mother board designation as these units have several compartmentalized card/boards. Replacement board availability and location ( as I do not know your location ) is available from :
