My CRT TV displays a single horizontal white line across the screen. It will flicker and try to display the picture. If you smack it you'll get a quick picture then back to a line. After about 10-15...

The single line means that the vertical deflection doesn't work. And since it is working when you kick the tv or has warmed it's clearly a bad connection - open the case and reseat the wires going to the tube coil.

My sound comes on and the picture does not right

This could be a vertical deflection problem waiting to happen. Have the vertical IC replaced on this unit...
Seen this problem before, also have a technician check the IK kineing Bias circuits, could also be cold solder joints that do not make contact until the televisons warms up.

White Line Across Television

If it is just a collapsed picture and view as a white horizontal line across your screen. Loose vertical IC connection or is start ailing. Best is to reflux its pin with a new lead or resolder it.

But I don't recommend you do it yourself if you don't have experience doing it.

Nasty voltages may caught you.

TV picture flickers

If your DVD player is separate from your tv, you might have a loose cable plug or connection. Depending on the type of flicker you have, a vertical circuit loose connection would cause this. If you could connect it to a cable or antenna it might tell you where the problem is located. A faulty circuit in the DVD might cause this too. Stargazer

Flickering Picture?

Your set might have a high voltage leak and that is the noise you hear when is showing the screen problem or even maybe an arking too ,either one is related to the high voltage and it can be dangerous,if you are familiar with tv service you can try to see where is arking and replace the part with an exact replacement but if the set has a leak you will not see it and is not safe to be close to it,if you are not too familiar be safe and call for assistance from a servicer.
