1968 "TLC" SS color set?

[Cruiseomatic]

I have all the fine adjustment knobs. Still can't figure out the picture brightness issue. This thing is a headache now. It is'nt even fun anymore.

Edit: I pulled the boards and cleaned the contacts, problem still there. It is amazing it still worked with the condition it was in. Doing what I can to clean it up though. I didn't think I would get it as clean as it is now siting on the bench. Once I get the picture solved she'll be done with the exception of the knobs and face. Should make for a nice shop television. It isn't to special to me. Just a mid 70's Japanese set. But I still had fun with it. Someone here might like it. I have a '79 Zenith I like which is why I'm not to crazy about the set I'm currently restoring. Like having two identical cars that are the same. Kind of pointless. Not to mention I don't like the steel cabinet. Just good for being solid but electrical hazard.
