We've had this problem before, but usually a reboot seemed to solve it. This time, it isn't. Knowledge (channel 5 in North Vancouver) is almost unwatchable. CNN and BC1 aren't much better. Is it a system problem or our unit?
Specific channels being out is almost certainly going to be a symptom of a poor connection. Cables and their connections degrade over time. If you haven't tried doing so already, you will want to unscrew and screw back in the cable anywhere that it makes a connection between the wall and the HD box. If that does not do the trick, we can route a technician for you here. Just let us know and we'll send you a direct message to collect your account details.
Most likely a signal issue
Start with the steps here, and report back if it helps at all How to troubleshoot poor picture quality / pixelation
Thanks for the connections guide, Kevinds. The channels I've discovered with the pixilation problem are (in North Van) 5, 21, 33, 40 and 42 (all HD), and VOD (SD). So far I haven't checked higher than 51, so there may be others. All other channels are fine.
I've rebooted again, waiting a minute, and checked connections. All splitters and cables are Shaw. The other tv (an old analogue) is fine.
When I started writing this update, the pixilation was still going on. 15 minutes later (a half hour ago) pixilation suddenly disappeared and all is normal on the above channels. 5 minutes later it started again. A few minutes later it goes back to normal (and is normal now).
So, my question is why those channels, and not others? Is it the box (which I suspect and is rented), or is it something peculiar to that set of channels, and thus the cable delivery?
Channels are delivered on different RF (radio frequencies), and its often the case that only a certain group of channels will be affected by a signal delivery issue. The channels also won't necessarily be sequential and can seem like a random group of channels. To resolve this we need to find and address whatever is causing a problem with the signal to your equipment.
You mentioned that there is a cable splitter? Even if this splitter was installed by Shaw, the splitter could be contributing to the problem. Are you able to test without the splitter by connecting a cable directly to the digital box to see if the problem goes away? If for any reason that would be difficult for you to do, just let me know.
Thanks for the explanation, [shaw]jeff. I rebooted again (twice) to no avail, The same group of channels are all broken up and unwatchable. Unfortunately they are amongst the most that we watch. I also checked re the splitter. I am presuming that there is one at the main entry to the house (for a phone and a second TV) but it is not easily accessible. The main TV is on a cable coming directly out of the wall (as it has for 50 years). The phone and other TV are not affected. So I suspect it is the HD box.
I will call Shaw tech, to see what can be done. If there is a wait time (as in days) then I will return the box and get a replacement (its rented). Thanks for your help.
You did it! (I think), [shaw]noah. I had fiddled with the connection but obviously not enough. This time I completely unscrewed the cable from the box then screwed it in again. And voila, the channels are working fine again. Thanks.
