Help me pls1
ok two things here, if it a realy old tv, check and see if it has a vert control knob that you will use to adj the vertical rolling.
are you on a cable box? if so bypass the box and plug the cable directly into the tv bypassing the box, if this works box bad get exchanged.
2nd if it is a new tv, try this, when putting you cable to the tv do it slowley and watch the tv, as the cable gets close to rf imput on tv dose the pix get clearer untill to cable is pluged in all the way? if so you have agc overload and the simplest way to fix this is get a antenuator, this is a small screw on device that will cut the siginal streght down and will stable you picture.
