I have a42 inch rca tv it gives a sound but no clear picture it has lines that runs thru it what can i do?

If it is an analog TV (not digital or HDTV) then you need a better antenna, better antenna connection, or better cable connection. Or you need to be more specific about what lines you are referring to going thru the picture. Have a friend who knows something about TVs look at it or seek help from a service professional.





Too many people use the push on cable wires that come with VCRs and those cause picture problems especially on TV cable due to the lack of a good connection and poor shielding. Always use 75 ohm, F connector cables that screw on finger tight.
