VERTICAL LINES FROM TOP TO BOTTOM WHATS THE PROBLEM AND HOW TO FIX IT

If those are real fine lines all the way from top to bottom, that is a section that has failed. I don't believe there is a way to repair it.

there could be a problem with your graphics card (this is called vertical lines on LCD), if this is a desktop, try removing the graphics card and use the integrated graphics card(built-in) and see if you can still see those vertical lines. hope this helps

Is the picture overall too small by 1 in. on top and bottom? Or is it cut off by the lines?

If it's too small, look for an adjustment labeled Vertical Height. This may only be accessible internally, it's normally a service adjustment, not a user adjustment.

Your problem is a vertical deflection issue, either an adjustment or the vertical circuit requires repair by a technician. In the latter case, electrolytic capacitors are a likely cause.

replace the dg board
