TV picture keeps freezing

AJM3 · ‎12-11-2011

I have a lot of receivers in my house. I have 8 of them. With the exception of the main receiver, the picture freezes from time to time on the other tvs. I have to change channels or turn the box on and off to restore the picture. Customer service suggested I unplug some of the receivers so they are not using the signal. As you can imagine, this is a pain in the neck when I have to run around and plug in the guestroom tv and unplug another one. Short of going back to cable, does anyone have a suggestion?

Please download UV Realtime, install it, and post screenshots of the IP/Profile tab, Bitloading tab, Error Table tab, and Coax/HPNA tab.

To post screenshots here in the forum, use the Insert/Edit Image button (looks like a tree icon).

If the STBs are asleep they are not "using" a signal. Using a signal does not cause freezing. It causes error messages that a stream is not available for use on the new request.

If you can live with four streams on eight viewing stations, it should (be made to) work for you.

With eight receivers you must be on COAX. If your main receiver is working OK you probably do not have a line problem.

Possible coax problems - bad coax, barrel connector in a line, all connectors on end of cables was not changed to compression, bad diplexer, bad splitter, too many splitters, splitter connected wrong, loose connection.

Can you connect any STBs via cat5 - even temporarily?

Can you eliminate any splitter?

Can you disconnect all/most legs to see how well it works? Then add legs or swap to a different group?

The purpose of this is to find the bad leg.

Any interest in going all cat5?

If you are cat5 already, the same trouble shooting applies - eliminate & add in to isolate a fault.

I've got the picture freezing problem as well. I've only had UV for a week and the problem has been there from the start. I've got TV and Internet (12Mbps). The technicians have been out 3 times and replaced the TV reciever and all of the indoor and outdoor wiring. I downloaded the UV Realtime app yesterday and ran it for most of the day. It showed about 10 corrected block errors every hour. On a whim I turned off the 2wire router on my computer and the freeze problems disappeared. When I started the router back up they reappeared. AT&T is scheduled to come out tomorrow to check into the problem again.

I tried to run the UV Realtime app just now and it will no longer run. As soon as I launch it a window appears saying that it stopped and windows is looking for a solution. It is possible that windows installed an update overnight as the computer was rebooted this morning when I first looked at it. Any ideas about UV Realtime and/or why my picture freezes?

Thanks!

macanudo1958 - You say - I turned off the 2wire router on my computer and the freeze problems disappeared. When I started the router back up they reappeared.

Sounds like that is the problem. What is that? It is not the RG. If you turn that off you will have no service. Is it yours or was it provided by att?
What does your network look like? Are all your TVs connected to the RG. Dont't mix TVs and computers on the same switch.

macanudo1958,

Please uninstall and reinstall UV Realtime and see if that corrects the problem.

If it does, please post screenshots of the IP/Profile, Error Table, Bitloading, and Coax/HPNA tabs. We may be able to see what is going on.

I am new to U-Verse so I ay not have all of the terminology correct. What I think of as the RG is a box located outside of the house. I have another box inside which I believe just supplies power to the outside RG but also has a cat-5 cable going to what I call the router. The router is a 2Wire i38HG and functions as the LAN and wireless routers inside my house. There is a coax line running from the box outside (RG) to the set-top box by the TV. It is a CISCO IBS7500. I only have one television.

I uninstalled UV Realtime and all of its installed components. When I reinstalled it worked again. Here are the screenshots you asked for. Any help will be greatly appreciated:

After seeing all those errors, I'd contact David and his tier2 team here:

Follow the directions under TROUBLES w/UVerse or install problems and hopefully they will solve your problem, let us know what happens. Good luck.

So I finally figured out the problem. Before I had U-Verse, I had internet service via Brighthouse cable modem. When the AT&T techs set up my service initially they mistakenly plugged the internet feed from the cable modem into one of the LAN ports on the U-Verse modem/router. Everything appeared to be working ok so the mistake was not caught until I decided to re-check all of the wiring. I thought they had scavenged the cat-5 cable that went to the cable modem to use with the AT&T modem but they had not and both cables were identical.

I had noticed that the activity light on the U-Verse modem was going crazy all of the time; even when my computer was turned off. I had mentioned it to one of the repair techs but they said it was normal. When I discovered the problem and disconnected the cable modem the activity light started behaving normally. Apparently, the internet feed from the cable modem into the LAN port caused a lot of packet errors thus eating up a lot of the bandwidth and causing periodic buffering problems.

It was a stupid mistake but I'm probably not the first person it has happened to. I wanted to make sure and document it here so that everyone else who is having problems will know of one possible solution. I have to say that overall I am happy with AT&T service despite the problem. They have been responsive and as anxious to fix my problems as I have been. Sometimes simple things make for big problems that are difficult to isolate.
