Regarding the bright pic going into the loop through, this is probably because it expects to have a 75 ohm termination, and you are not terminating it, resulting in twice-normal video level.
There was a known issue with Zenith TVs of the era and something "confuses" the sync system (probably not a great description but that's my memory of the issue). Apparently game console companies had a fix they provided free but it was at the game console level, not the TV. And it happens with AV inputs OR antenna inputs.
