42 in Panasonic flat screen

[Tony day]

I have a 42 in Panasonic flat screen with video only I have a Digital convert box and I can not get no sound when I hook it up in the back of my TV the only way I can get a picture is to only hook up the yellow wire only and no color on it either what should I do

Depending on the available ports and viable TV menu configurations you may have some choices.

Here are two links that can provide some guidance provided you can match the ports on your devices:

Many TVs have a shared component (3 RCA jack) and composite (1 RCA jack) input. You will have to go into the TV menu and set the input to composite to get color.
Audio is a separate connection requiring a standard RCA stereo audio cable. The red and white jacks are for audio.
