Major Dish network Problem

09.09.16

Guys,


My boss is having the strangest problem with his DISH Network 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. All this was done about 12 years ago.

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 (17") 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. DISH Network 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 technician 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.

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 connections 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, in fact the television image in the second room had gotten slightly worse.

I then bought a new piece of RG6/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.

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.

According to information that I have recieved the 625 reciever is not a HD reciever but it was connected to the Sony KDL-46W4150 television in excess of a year with no issues. The reciever was connected to the television by the coax wiring as well as a component cable. I believe that the Video1 input was selected.

Please advise us on any solution that you might have. I am thanking you in advance for your assistance.

Ok, try making the connections simple, first disconnect the coax, are you still having the issue on the input. you can localize the problem. It sounds like you have centralized distribution throughout the house for what was originally intended to be a cable connection. Unplug one of the 625's to see if you are getting a dual feed though the same bandwidth. if this is not the case. The troubleshoot further, barrelheads casue issues. To trouble shoot , run a cable going from the receiver directly to the tv ( you'll have to run the cable through the rooms in the house temporarily to see if the direct connection eliminates problem, conversly just bring tv2 to where the receiver is and connect the coax right there to see if you get this ghosting type problem )

Thanks for your post.

I did try the disconnecting the coax but it made no difference that I could see. Yes, the house was wired for distribution throughout the house but for legacy satellite connections. The power inserters were in the attic and one LNB feed ran to a patch panel in the main room, with the other feed run to the master bedroom. This was done approximately 12 years ago. The barrellheads are brand new from the dish net. service guy replacing all of them. I did get a piece of RG-6 and make a test cable with it. I ran the cable to the reciever in the main room and connected it to the LNB for the main room. There was not appreciable change. I then relocated the cable to the reciever in the secondary room and left it connected it to the LNB for the main room. There was no appreciable change.

I have not done the following:
Unplug one of the 625's to see if you are getting a dual feed though the same bandwidth. if this is not the case.
What would a dual feed do? :what: As it stands each reciever has it's own feed line from the HD dish LNB array mounted on the dish mast. Please explain this, I really would like to understand this.
