What could be the cause of vertical lines at the screen of a Vizio tv?

The sound and other functions seem to be ok. Below I',m sending a photo of the screen as a sample of the problem.

Possibly one or more defect column driver chip(s) on the LCD. Or contact problems in the connection between LCD and mainboard.

This is a problem I see very often on LCD panels. Mainly smaller panels and in every case it has been the LCD panels at fault
quite possibly for the reason Harald stated

Possibly one or more defect column driver chip(s) on the LCD.

Chip-on-flex issue..... my laptop does it now and again! A 'press' along the edge of the display often cures it - sometimes for minutes, sometimes for days. I'm looking for a new screen for a permanent fix.

I've seen semi-permanent solutions using elastic foam to exert the required pressure once the screen is reassembled.
