Aha. Yes, start with the obvious. After I recapped my CTC-7, including chroma circuits, it looked so good that I did not mess with any of the color setup. Sometimes it's better to let sleeping dogs lie.

Is the chroma located in the underside portion of the chassis? Because I don't see it as a board.

Under. Note the yellow and orange caps in this photo of my CTC-7:



The pile of "brown drops" and one bumblebee show what I replaced.

Basically all the brown drops? Some of them are just buried in there. By the way a big thanks to you Phil for helping me out.

I believe I replaced all of them. The failure rate of those on the boards was so high that I couldn't justify keeping that type of cap anywhere in the TV.

I recommend trying out the TV frequently as you recap, rather than replacing all of 'em at once. If you make a wiring mistake or install the wrong value cap, which is easy to do, the problem will be immediately obvious and you won't have to go nuts trying to find the error amongst two dozen replacements.

At noob-level experience, it'd probably be advisable to power-up after each part is replaced (IMHO).

Well going to need more caps I guess.
