TV frequent outage

TV frequent outage

My tv goes blank every omce in a while.  Not off, just blank.  After a while at the bottom left it says 'No Signal off remaining 5 min.'  After 5 min. it shuts off.  If I wait 5 to 10 min.  I turn it back on and it works.  What's going on.  When this happens, my computer goes haywire too.

You will have better luck with this question in the TV forum (this is the website forum). Do you have X1 or non-X1 set-top box?  It sounds like there may be a power-saver feature turned on within settings. Try changing the channel using your Comcast remote control when the 5 minute message appears to confirm.  Your TV probably shuts off 5 minutes after the cable box to prevent burn-in and conserve power.
