I have noticed recently that on one of my 3 boxes that some of the HD channels have an extremely small picture (including guide) as well the sound cuts out frequently. I have reset the cable box and TV with no success.
Not all programs on HD channels are presented in a widescreen format which will fill a widescreen TV (but you may already be aware of that). Are you seeing black bars on all four corners on certain HD channels? Also, can you confirm that this never changes for any program you're watching on those channels (while other HD channels appear to be unaffected by this)?
The sound cutting out is likely a separate issue. Do you sometimes notice that the picture will freeze/break up as well, or is it only the sound that is affected? Can you tell me what type of cable you are using for audio from the HD box and if this is connected directly to your TV or to an AV receiver/speaker system?
That's correct, there are black bars all the way around the entire screen but only on CBC and FOX from on the HD channels, all others are sized appropriately for the TV. I do realize that some channels come in at different resolutions but these two channels only started acting up a week ago and I had never had this issue before. The issue does not waiver, it stays the same resolution whenever I am on CBC or FOX however when I return to another HD channel of SD it goes back to regular size.
I did fix the sound by resetting my TV again so that is not an issue any longer, just the picture.
I am connected by HDMI directly to the TV from the box.
Good morning sthomas
You mentioned that even the guide does not fill your screen when you tune to these channels? If so, that is quite strange. We may want to try resetting the Box. Have you tried a power-cycle yet?
To confirm, while watching the same program on all your boxes, only one has the issue?
Check the output resolution setting on the box is set for 1080i rather than 1080p (I remember an issue that would cause the smaller picture).
