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 :
your tv is working but your antenna or recieving device is not sending a strong signal to your set, try using a hd antenna or a dvd device maybe a cable reciever or similar, to see if your able to see a picture but usually its a signal problem not something wrong with your set.. hope this helps
it needs service, that means using tools and meters and spare parts to find cause.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge)
As a first step , if it is controlled via the remote, check that the remote batteries are good and that it is functioning ok. Does the tv show anything att all? If it does come on but shows nothing then it might be that the source selection is on the wrong kind of source, you can find on the remote whether this is so by going to the source menu which should probably be on digital. (I am assuming that you only have digital broadcasts where you are.
If there is no picture whatsoever ubplug the set and check whether the internal fuse(s) are ok.)
