Actually, if you hook up your DTV box, then set the tv to channel 3 and get a B&W picture, you should verify that your fine tuning knob is actually working..... Can you fully de-tune the channel you are getting a signal from...? 3, or 4, whatever you are using..... And you should get past the leaving the set on for only 30 seconds.... Some of these old sets need a few minutes for the color to work, If it comes on after a few minutes, that's a clue to fixing it....
