I've got one I'm trying to fix. After replacing the RCA cord and attaching a coax adapter, it's working but there's a lot of static. Wiggling the RCA cord around ranges from total static o screen to pretty clear, so I'm not sure what the issue is. I initially thought it was the RCA touching the metal casing but still trying to get to the root cause. Any ideas? See sample vid with artifacts + photo of replaced RCA.
