Vertical lines appear instead of picture

LC-55N7004U almost brand new, tv was bumped into by children playing. It still powers up and off. When I unplug it then plug it back and turn it on, the “sharp” logo displays perfectly but when the logo disappears and the tv menu should appear I just get vertical lines of colour. I plan to take it apart to look for a loose connection somewhere or other visible damage. Any suggestions?

Update (04/25/23)

it appears As though the tv is displaying the screen saver pictures it would normally rotate thru but they are displayed as vertical bars of colour instead of a crystal clear photograph. I’m attempting to attach a 30 second video of the tv boot up to this message.
