A single set of horizontal lines could indicate damage, a graphics system failure, or loose internal video cables. Broken signals from cables or graphics hardware creates impurities in reproducing an image on an LCD screen, conditions that often manifest in the form of vertical or horizontal lines of color. https://itstillworks.com/causes-horizontal-lines-lcd-panel-37988.html

Hi.. Mine is a sansui tv and I bought it 3 years back. Now it is showing a horizontal line on the screen. Sound is fine but I can't see the picture, I just see one white horizontal line on tv...

The problem is vertical failure. Vertical output section to your TV ahs the fault. You ahve to check the vertcial output circuit for any component failure or loose solderings.

Horizontal line on screen sometimes

Generally horizontal lines are caused by the panel failing, you can try a new tcon but I don't think it will help.

This could be a capacitor if your lucky but can also be the horizontal transistor. The repair could cost you between 60$ and 150$
My opinion; it's not worth it.
