My Picture keeps Flickering and The only Sound is a White Noise?

I bought my TV from My Grandma to help her out, and when i hooked it up to my PS4 Pro it started Flickering and Jumping, im not entirely sure what is going on as i had my PS4 Pro hooked to a 4K with No issues. the other ports are not operational. When i turned on the Sound it is so distorted and primarily just makes pink noise/ white Noise. Im thinking it could be dust or the Logic board is dieing… Can anyone help or is my TV a lost cause?

ANSWERS:

like @jayeff already pointed out, we need to know the exact model number/ This “the other ports are not operational. When i turned on the Sound it is so distorted and primarily just makes pink noise/ white Noise.  “ is usually indicative of a bad main board. You would have to remove the back from your TV and take a look at the boards and the wiring. Vizio is a mediocre manufacturer that has issues with properly soldering connector to boards. Check all of them and reseat the cables. Post some pictures of your boards etc. with your question so we can see what you see and possibly identify problem areas.
