My TV blacks out every so often when I am watching a cable channel. It doesn't do it when I am watching Netflix or other internet applications. I replaced the HDMI cable between my Shaw cable box and the TV but it is still happening. When it happens I change the channel and then returned to the blacked out channel. That seems to correct it. How do I stop this from happening?
Which Shaw cable box do you have? How old is it?
Does that box have the capability to pause/rewind/scroll-backwards? (If it does, it has an internal disk-drive, which might be having problems that trigger the black-outs.)
Do you have an external "Shaw Expander" (external disk-drive to add capacity to store more programs)? Again, any problems with that disk-drive can cause your symptoms.
I have this problem too. New blue curve system. Everything is hooked up correctly. Recently had a Shaw tech out to the house. Would appreciate a reply on why the tv goes black periodically and then comes back on. Same problem exactly as described.

When the "feed" to your TV temporarily stops, your TV goes "dark".
This probably is a "signal strength" issue. Contact Shaw (www.shaw.ca/chat) or 1-888-472-2222 and ask them to remotely logon to the Shaw TV box, and to view the "signal strength" reaching the box.
@dj16 -- no error message. audio continues
What manufacturer and model-number is your TV?
Does it have an OSD (On Screen Display) where you can set the time before it goes "dark" ("power-saving mode") ?
