Greetings!
From your photo, it looks like you have some smearing, but only in the chroma signal (assuming black and white reception looks normal.) If I remember right, the chroma circuit board has a bunch of little peaking coils, which like to go open and cause strange color symptoms. These coils look like really thick ceramic capacitors, with the leads installed in such a way that they pass through the body and stick out with little stubs on the top of each part. With your trusty ohmmeter, go on a hunting adventure for coils which are open - they normally measure just a few ohms so when you hit one which shows thousands, you've found the culprit in all likelihood. (You can even take your test measurements at the two little "stubs" that protrude through the part body.)

If you want to do the job right, you'll need to hunt around and find a replacement for any coils found to be open. But I've found the results to be virtually identical simply by replacing the bad coil with a piece of wire. I suspect that if you replaced all the peaking coils in the entire set with pieces of wire, you would significantly degrade the performance, but just a single coil here or there seems to be pretty much un-noticeable.

Good Luck!
