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.

My opinion; it's not worth it.
