[net.video] RCA TV problem

I recently bought an RCA model FLR 2022T TV/monitor, which is
great except for one thing:  when certain tapes are broadcast
(e.g. news clips, sports highlights), vertical edges in the
picture generate a whole series of echoes (up to about 6) as 
if a circuit is ringing.  You wouldn't believe what Yankee 
pinstripes do to the picture!  These echoes are fairly close-
spaced, but easily resolvable.  This only happens on tape 
transmissions, and live broadcasts are crisp and clean.  I
suspect some sort of interaction of the taped signal with the 
comb filter in the video circuit, but that's only a guess.
The effect is the same if I take the video output from the 
tuner in my VCR and feed it directly into the monitor output.
On the other hand, if I split the RF signal and simultaneously 
view it on another TV (without a comb filter, but with good
horizontal resolution), there is just a hint of echoes on the
other TV while they're still bad on the RCA.

I've spoken to several friends with comparable model RCA sets,
and they haven't seen any such problem.  Since the warranty
has just run out, I'm not anxious to bring a serviceman out
without a clear demonstration of a fault.  Murphy's Law would
assure that he would only see clear live pictures.  Has anyone
else seen such a problem, or have an idea on what might cause
it?  Any help would be greatly appreciated.
