This turned out to be a simple fix. Surface mount coupling cap, C18101, to
pin 51 of the PIP ic, U18100, was contaminated from mounting glue which became
conductive, about 6 megaohms. I have run into glue contamination on other
CTC187, 197 and 203 chassis. Anyone else seeing this type of failure more and
more?
Thanks again.

Correction: As pointed out by several people, this model is an F32715. I wear
trifocals and a 5x magnifying visor assisted with a 4x hand lens. I think I
am doing pretty good to find my coffee cup and the toilet roll on some days
without mixing them up.
Bob Waterman sent over a Sams pdf that seems to be sufficient. Thank you,
Bob, and to all who offered assistance. I may be back on this; will post
repair.

Can someone please help me on this?
Need at least the luminance and PIP section for this set. Few tips, none
which help on this one. Dark main screen with good OSD and b/w PIP. Loaned my
RCA
copy to another shop and the guy closed down and skipped. Thanks,
