Have TV Questions? Ask a TV Technician
Welcome. I am Mike, an experienced field technician. We are now connected together on this convenient website where I am able to help you. To get started, I need to know you can see this message and are able to reply to me here...
-If you connect something to this tv with a normal length 6ft connection cable, does the picture look normal?
-If you bring up the tv menu using the Vizio remote, is that menu clear or does it also show these wavy ghost lines?

Are you having website difficulties that are preventing you from replying?
If you are 100% sure the menu screen is not affected then this is likely a failure with the Main board in the tv and the board will have to be replaced.
There is a small possibility of a "ground loop" issue. You can try plugging the tv into an extension cord from way across the house (different breaker than it's on currently). But I doubt it will be this.
If you want more details, I suggest you reply with the full model number of the tv, purchase date, and if you want to attempt to work on the tv yourself...
