A challenge indeed......

What's known good: Each of the three projectors (red, green, blue) are
fully operable and in focus. Audio is unaffected and functions well.

The symptom is akin to the effect viewed as a partial signal block from HBO
in the late 1970's. where the picture shows up on screen with a wavy
horizontal flickering side to side motion. Depending upon the input signal
strength, the horizontal wavering strengthens as the signal gets stronger.

When using an antenna ( tested both antenna 1 input and antenna 2 input),
Channel 8 can receive marginal reception as the the channel is broadcasted
from 45 miles away. Some snow (weak signal indication), a little spotty
(microwave background distortion), but very few wavering lines as compared
to viewing a VCR/DVD input. All other channels are too distant to receive (I
have not activated cable TV yet). On channels without formatted broadcasted
signal received ( snow microwaves only), there is no indication of wavering
lines at all, and no indication of a malfunction.

With the input coming from either video 1 or video 2 (front and back tested)
having an 8mm camera connected to the TV, and active, and panning the lense
to the kitchen (not so bright), horizontal distortion exists. Then when
panning the 8mm camera to view through the window outside in the bright
sunlight, the distortion intensifies and the video output on the TV screen
becomes unrecognizable.

Without any signal input showing up on the screen, in the case of the full
screen TV setup menus, all text colors and text are sharp and background
color is picture prefect. This is also the case when the vhs is connected
and the stop button is pressed) with a tape active but not playing. The
output is the pretty blue blank screen (normal attribute in this scenario)
and the display statistics (date, time, position counter) appear in picture
perfectly clear white lettering.

If you have any TV experiences / thoughts to share (however
trivial they may appear), I'd appreciate your input.

Many Thanks,
Ken
