Hi-
Try removing and reinstalling the cables from the back of your TV.

Look around this sight the answer is explained here. you hace to take off the front speaker cover and a small panal undder it. you will find six knobs on a small panal. use these to adjust the settings fotr the power and they will remove the lines. You will need to have the tv on and I would sugest a normal size phillips head screwdriver not a power tool.

Good Day, LDS also;
You may have a poor seated cable connector. Unplug TV from A/C, remove back look for a large black connector. It connects between the Main Digital Module and the Drive PWB. Re-insert both ends several times to make better contact, use contact cleaner if have but not always needed. Good Luck, big IRISH.

module problem take it to a Authorized dealer or a NESDA dealer service manuals hard to say if available since analog TVs are slowly going away and parts well another story might as well go buy a new HDTV set as a CET no garuntee how long it will be analog TV parts will be discontinued. FCC has alot to do with it.

Vertical problem coming from bad solder, or vertical circuit problems!!!
Check for bad solder and capacitors problems in vertical circuit.
