HELP Video problems with 32" Zenith

[Gamer of NC]

I have a 32" zenith tv made in 1998 the RCA video in just went out the
only thing that comes through is red/black you can barely see what
coming through???? The cable works fine but when I play DVD/PLAYSTATION
it very dark only red/black?

RF input works ok but AVIO does not function? Suspect anything from poor
solder connections at the physical RCA jacks all the way up to the AV switch
ic. Time to do some in depth troubleshooting.
