TV blacks out

[Dave54]

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?

@Dave54 Do you receive any error messages when this happens? Does audio continue to play with just no picture? 

[Dave54]

No, I don't get any error messages and the audio does not continue to play. The screen just goes black and it stays black.

@Dave54 sorry for the delay in response. What troubleshooting steps have you tried so far? It may be a signal related issue.

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.

Happens to me all the time. I have only ever been able to fix it doing exactly what you describe.

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.

@debbiewalline -- Would appreciate a reply on why the tv goes black periodically and then comes back on

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") ?
