I have first color tv old!

I'm glad the set made it home safe. Do you have a tube tester? If not, you will need one. Change the 1V2 focus rectifier tube (it's a little tube that is by the high voltage part of the tv which is that big metal box on the right side of the chassis.) This tube sticks out sideways from there. The focus control is a plastic stick at the back of the chassis that is below it. Slide that in and out for focus. It has a locking screw that holds it in place. The lack of color is most likely a tube in the color section of the chassis that is bad. I've had several of these sets in the past, I wish I were closer to you so I could help you work on it. And please follow snelsons advise on not turning knobs unless you know what they do. The greyscale or black and white part of the picture looks ok for now so don't turn the color drive controls on the back, they are the controls with a red, green and blue shaft. The best place to start on this one is checking all the tubes, the picture tube looks ok to me, it's bright enough that it will produce a nice picture once the chassis is right.
