Guys,
In reference to #post121028 with the thread heading of "fuzzy-picture"
started on: 08-22-2004, 10:50 PM.
My boss is having the strangest problem with his Direct TV system.
I wired his house when it was being built and used the standard barrel
connectors to make patch panels and wall plate connections. There
were no spliced wires using barrels, all unbroken RG-6 cable.
The system consists of (2) 625 recievers, one of which feeds the tv in
the living room, a Sony KDL-46W4150. The second feeds a smaller flat
screen in a adjoining bedroom. The second also feeds a larger analog
tv in the master bedroom. The master bedroom is backfed the video
signal by patch bay connection and controlled by the wireless remote.
A week ago the reciever in the second bedroom went out. Direct tv was
called and a service guy came out to see what was wrong. I was not there
to observe the following 5 days of work but I have been told that the
ftechnician ordered a new reciever and it did not work. The technician
then replaced the older superdish with the newer HD dish. It still did
not work. Then the technician ordered a second reciever and it did not
work. The technician then checked the coax connections and found a
burned barrel connector in the attic space where the sat. wires come
from the dish and are connected to the house wiring. At that time he
found them to be the older white barrel connectors. He replaced all of
the barrel connectors with the newer blue barrel connectors. This
corrected the problem with the second reciever.
However, a new problem showed up. prior to the repair of the house
wiring, the screen images were clear and undistorted. Now that the
above described modifactions and repairs were made the screen images are
not clear and are distorted. On both flatscreen tv the pictures are not
clear. There is a unfocused area around moving images like when a face
talks or when a horse walks the legs are hazy. There is also a "smeared"
halo around text displayed on the screen. Now both televisions have been
tested using DVD video from playbacks of movies and the images are clear
and sharp.
I did watch the technician adjust several settings in the 625 with little
,if any, improvement in the screen image.

UPDATE
This date I went to my boss's house and checked that all of the connectors
were at least fingertight on their fitting. I checked that all feed and
interconnect wires were tight on the back of the wallplates. Several
connections required more than a 1/2 turn to tighten them. I then checked
all of the interconnect wires and connectiontion in the attic spaces. All
of the wires looked to be in good condition. Serveral of the wire connectors
had to be blown out to remove misc. metallic debris. Several connections
required more than a 1/2 turn to tighten them. The state of the television
images were then rechecked. They had not improved, one had gotten slightly
worse.
RG6/U Not RG8/U
I then procured a new piece of RG8/u and 2 end connectors as well as a barrel
connector. I then disconnected the wire from the house to the main room dish
LNB. I connected the new wire to the LNB by the barrel connector. I then
connected the new wire to the 625 reciever in the main room. The state of
the television image in the main room was then rechecked. It had not improved at all. Next, I disconnected the wire from the house to the second room dish LNB. I connected the new wire to the LNB by the barrel connector. I then connected the new wire to the 625 reciever in the second room. The state of the television image in the second room was then rechecked. It had not improved at all. It had gotten even worse.
I reconnected all the orginal feed wires back to the 625 recievers that they
were connected to. I cleaned up the work site and stored the test wire at the
site.
Please advise us on any solution that you might have. I am thanking you in advance for your assistance.

It also turns out that the cablevision varity barrel connectors do not like having 18Volts DC or more pushed through them at a fair current.
