[C64 Scrolling Black and White READY Screen Fix?]

So recently I grabbed a breadbin brown-with-black-keys C64 for $35 because if it didn't work then it had two working PSUs and a good condition box. When it got here, it kept black screening until I had started messing with the RF cable. It gives me the screen in the picture, but I have to take out the RF cable, put it back in, turn off the system, turn it back on, flip the channel select to the right then back to the left. I'm thinking the RF modulator is dying in it and that is all, but I don't know. I want to get this thing having the blue on blue READY screen like my other C64, but don't know how. Any help is appreciated!

 

Had exactly the same problem on a couple newly acquired C64c machines

Tried 3 different LCD monitors using video, S-video and RF with no change in results

Then dug out an old Toshiba CRT and it worked right away on all signals

I guess using vintage with vintage works best :)
