[TV] What can be causing pixelation on *some* channels.

Getting issues on some of my channels.
My setup:

Cable in to two-way splitter, one splits to Home Phone, one splits to 5 way booster-splitter, 3 goes off into cable land, 1 goes of into the land of the internets (invented by Al Gore). 1 Free. (I have VIP).

Channel most likely affected is Channel 16, for example, the weather channel..and channel 5 too, quick a bit (Well, view CBC isn't a priority for me anyway)..all my HD comes in perfect, except with those channels I listed, plus a couple others. It seems to happen on the channels below 90.

Anyone else have this issue? This has been ongoing for some time...just haven't had the time to call them...(they rewired from outside of house to pole...maybe that was faulty)

Are you using DECT 6 phones? If yes then move the base station to a different location - you may need to play with changing the location and see the impacts. If no DECT 6 phones then your signal quality may be the issue.

Did you install the splitter yourself? Or rogers supplied? Often in many cases amplifiers are installed unnecessarily when there are other problems, hoping that they will fix the issue, when in fact they do nothing or exasperate the issue.
The other thing it could be is the box. What type is it? 8642, 4642, 4250, 3250, 8300? If it's a cisco (8642/4642) much less likely the box but still possible.
You can swap out at a rogers plus store, knowing that if it's a pvr you can't keep your recordings unless you save to external device.

HOLY CRAP! Why the heck would these phones be giving issues?

Yes, have some the Panasonic DECT 6 - strange, eh?

Anyway, unplugged; seems to be good now...

Rogers did all the work. Unknown if I still need the amp.

I have two different boxes, the HD Cisco and the SD Scientific Atlanta, or whatever it was..both had issues...I rarely use the one downstairs so I never really checked it out too much.

Anyway, seems like the culprit might have been the DECT 6.0 wireless phones that I had. Really not sure why it would be the issue, but the other poster told me about it, I removed offending devices, everything is back. The DECT isn't the primary phone, so I will be only used when necessary now. (the base is still plugged in, but not to the electrical -- so no wireless transmission and no speakerphone)

I also had Panasonic DECT 6 that created problems with my Rogers TV stuff on certain channels. I also tried changing base station locations but that did not help. I switched to AT@T DECT 6 phones and no issues with my TV so I think that Panasonic DECT 6 does something very different. I contacted Panasonic but they never replied to my questions or issues.

BTW, it was a Rogers Tech [female] that actually spotted the problem [after 3 hours of troubleshooting and changing all my coax etc] with the DECT 6 phones based on conversations she had with her Tech supervisor.

Well...still get some minor pixelating....so the DECT 6.0 is a culprit, but not the only one. Plugged it in when a channel was acting up, got way worse....unsure why it only affects some channels.

check the signal strength on the STB diags menu. if its too low, or even too hi it can cause pixelation. also check for sh!tty spliters and see if u replace them if it helps, also check for loose connections and nicks in the cable tv wire

I had a similar issue a couple of years ago. In my case it was a new Panasonic Dect 6 phone clobbering a small frequency range. I think it was 711 Mhz. The only channel at that frequency I watched was CNN. I still have the same problem, but since Rogers added CNN HD, it doesn’t affect me. I demoed the issue to a senior tech and he was surprised when I showed him that as I moved the phone base closer to the PVR that the unrecoverable error rate increased and when I entered the room with it the channel would unlock.

Not sure its related, but we just switched to Cisco DTA50's and in one room, I had the square pixalation on A&E (Ch 31). I found a loop of about 20 feet of cable that wasn't needed. Removed that and it solved the problem. So it appears in my case it was a signal loss issue. This line is also on a dual splitter

Was the loop that wasn't needed part of the line (inline?) or was it just unused and running off the other side of a splitter? In other words, I am trying to visualize where the loop was located...

Are you kidding me? There is basically only one thing that causes pixelation that of course is low signal strength. Rogers is synonymous with low signal strength so much so that i've even seen pixelation on channels where there's no splitter just a direct line to one television set. Try it yourself use a direct line to one television set with a short RG-6 cable and presto still pixelation.

Long drops might be the real cause of your issue. If roger were to make shorter drops then they would need to add new taps and amplifiers on people's front yard and in turn people would whine and complain. So I guess rogers just doesn't want to deal with it but they do know what the problem is. Another reason why we need aerial drops.

What you're seeing is what is called "ingress"...in the analogue days you would have said "Channel X/Y/Z are snowy and fuzzy but all the other channels are the same".

Cable is a closed system so in reality no "outside signals" that use the same frequencies are supposed to bleed into the cable system as they use the same frequencies...not as horrible as "egress" from a cableco standpoint as Industry Canada gets cranky when that happens as it can cause interference with Airplane navigation stuff.

Sounds right if you unplug the phones and it goes away...for the most part...

This "free drop" you have that's not connected to anything, for fun, unplug it from the splitter...see if it goes away or not...I'm wondering if its not picking things up since its not properly terminated...

Its worth a shot, hey it can't get any worse right? If that's the case it could be the splitter that's the cause, and if Rogers installed it, they should take care of it...or remove the faulty wiring or replace it...but that's the culprit...

@kliles - Loop was the end of the run from the splitter that I was too lazy to trim down when I first ran it. It was active/inline

It also depends if you have close neighbors for example if you're surrounded by townhomes where it can literally be 3 feet away.

Houses in this area, and across the street from a forest greenbelt. Not to say a neighbour nearby wouldn't be the issue. Feed is coming in from a pole in the backyard.

Pixelization can be from any number of reasons.

Here's a bit of a rundown...

There isn't really a way for you to check your connectors as they're relatively locked up in the CSE and PED. Sometimes water can get into the connectors and as a result, corrosion occurs which leads to pixelization/missing channels/etc. Some techs don't install connectors properly and if they're not on properly, this again can cause pixelization.

Non-Rogers splitters, amplifiers and even cable (white store-bought RG6, Futureshop cable, etc.) tend to cause issues as well. Replacing any customer purchased drop amp is nearly a must in pixelization issues. Ensure everything is Rogers equipment and hardware or else it could be the issue.

Poor signal...try to pull up your STB diag. If it's a Scientific Atlanta box, hold the middle select button on the actually STB. When you see a little envelope on the screen, press the "Info" button on the STB. Now use page up/down on the remote for diagnostics. General rule of thumb is anything orange or red is bad. You want +10 to -10 for your FDC/RDC, but generally real issues don't occur until about -14 or so. A tell-tale sign of pixelization is on the 4th or 5th page at the QAM info. You will see QAM Uncorrected Blocks and QAM Corr Bytes. This number SHOULD be 0. Anything higher indicates an issue.

The issue is often a riser (line) too. Some customers accidentally staple through their riser, kink it a bit too much, or have furniture resting on it. This causes issues.

Lastly, it may be an area issue. People are surprisingly tolerant of pixelization. I can't count the amount of times I've been at a call where a customer said, "yeah it's been like this for like 2 months". We techs have a program on our laptops which allows us to scan the entire neighbourhood or region's digital boxes health. Every single time I have a trouble call which says, "cx reports pixelization" in the comments, the very first thing I do is run that test. Quite often it is simply a "maintenance issue" where a maintenance tech is required to resolve the issue at the SHUB.

Your best bet is to simply call Rogers...if you get a good tech the issue will be resolved fairly simply.
