Read the suggestion of unplugging the TV for at least 4 hours to re-set to factory specs and that took care of it!

Cable box only works during evening hours.


You need to schedule a service call to meter the feed to the house. You signal is lowest during the day since everyone is taking up bandwidth for internet access, thus dropping the signal to unusable levels. Have them meter the feed from their tower to your main panel then from your main panel to the modem or any box. Hope this helps

Comcast Cable Down All Day Every Day


Here's some things to check:
If there are signal splitters on your cable for TV, computer, more than one tv, the signal is getting divided ...every splitter will weaken the signal.
Check for unneeded splitters, also there are splitters that have a wider frequency capability.
Consider upgrading to 2hgz splitters if needed.
Also I think that the more homes that are on the cable tend to make the signal weaker...I don't comcast would fess up to this, but I'm pretty sure it's true.
Make sure all your cable connections are snug and you may want to double check for corrosion etc. on each connection.
I resorted to a signal amplifier on my home. We've got comcast for cable tv and internet, with multiple tv's and multiple computers.
The amplifier (motorola) boosted the signal for everything and we've got way less dropped, frozen pix, black screens and the internet is back up to speed.
Comcast even came out and put a signal strength meter on the in-line to the house and stated it's within their limits... Glad I put the amp on the line..
Give it a try.

Splitter side of Comcast cable signal unusable. Converter box OK


DTR's are available everywhere. You can also go online and purchase one if your local stores do not have. Also, keep in mind that the splitter you use must comply with the signals unless you use the Video output of DTR.
