White lines and faint black Bars

Needing some direction on how to solve some issues with an old RCA TV set! Model GGR699SR

Issues are these odd horizontal lines mainly! I can adjust the picture dial on the back to darken and it’ll make them disappear for the most part but then my picture quality is crap (obviously old tvs) but still pretty crap. How do I solve this.

Other than that I have some faint thick black bars that go vertical. Not too noticeable but I’d love to get rid of them.

This is gonna be a nice little piece for our future retro room so I’m hoping I can get this tip top!

Any info would be great!

Sadly I can’t get a good photo of the black bars but hopefully someone knows what I’m talking about.
