I believe that model has the CXA1477AS jungle IC in it which is most
likely the culprit.
KV29XBR85:
>From Sony:
The original comb filter, DC1390 (SBX1653-01), on the B1
board is no longer available. The glass type, part# 1-464-880-11, can be
used in place, with very little noticeable difference in picture quality.
I can email you the modification that goes with the
new comb filter cct.

same model above:Subject

FIX: CM401.
The comb filter location "CM401" on rear input CBA I ordered fixed
it.See thread below for details.

Fulton Radio (1-800-248-0898 parts)was very helpful. They offer Sony
tech assist to their "active" parts customers. Another
words, you need to patronise them.Understandable.
On the rear "UA" board (the one with the audio/video jacks). He said to
replace the comb filter "CM401". some versions have two.
Part# 1-467-554-21 , available at Fultons. (resembles a crystal delay
line, black, square, 1"X1/2" approx)
We are pretty sure this is the fix, but will verify after installation
later this week.

Phil I'm not familiar with the FSC signal. I pulled the tip off the Sony
website. It specifically said "Ghosting in video but S video works". I
would really look for that resistor to see if it is touching a
component. If I find the location I'll post it. Gerry

Above are cut and pasted from Sony tech assist emails for assorted
madels. Hope they help. I tried to cut away all the fluff and just print
the meat.
