CT100 owner request

I have a lingering problem with my CT-100. I'm not sure whether this
is just my set, or a design problem.

The problem is that if the far left edge of the image, immediately
adjacent to the end of the horizontal blanking, is a near saturated
color, not green or magenta, it leaks into the tail end of
the "selected" color burst and causes the color sync to go wrong.
This appears as horizontal bars of wrong color. The size of
the problem varies with the position of the horizontal hold. At the
full CW setting it is weak or absent and at the full CCW position
where sync is maintained it is worst.

So I ask ... can anybody with a CT-100 check for this. You need
a test signal with a full intensity red, orange, yellow, or blue-green
color. It could be a full field or horizontal color bars. Such test
signals exist on most standard calibration DVDs. Just run the
pattern and see if it is the right color and if it changes as the
horizontal hold is run over the full in-sync range.

I can see the impingement on a scope looking at the burst
at the AFC diodes.

Thanks in advance for helping.
