That's likely the issue. If it's plug directly into the tv and is still having issues it's probably because it's a low quality cable. Unfortunately I have no idea where you would get an original one.

Composite interference on OG XBOX (1.0), anyone have remedies? | Spyke
What cables are you using? Have you tried higher quality cables?
Where would I get higher quality composite cables from?
Would a pre-owned Microsoft one likely be better?
How do you have it hooked up?
A composite cable, given to me by someone else. I don't see a brand.
After looking it up, this is definitely not the Microsoft one. Has similar moulding to like, the first results on Amazon and AliExpress.
