Thanks! Of course, when I sit down to try your procedure suddenly everything is working again with the remote. I really wonder if there wasn't something going on with the cable box last night. There were other odd behaviors happening along with the the remote seeming not to work. This isn't the first time having remote issues, so I'll keep this in mind for the next event.
HDTV Flickers Black for a few seconds ,when switching channels.
HD Box make / model: Xfinity / PR1508NM ( RNG150N )
HDMI connector fron box to HDMI connector to TV HDMI 1
I know there have been posts about this in the past ( for quite awhile , now ),
I contacted Comcast Tech Support, who says they haven't had a known issue like this before ?
Anyone know if the is a: FIX for this / Comcast problem / signal problem / HDMI cable problem ?
I have 2 HD boxes, ( same model) same problem
Apologies for the issue that you described above.
Pixelation and audio-video dropout issues are almost always related to local or individual signal or connection issues. The issue can occur on a single channel or multiple channels due to the frequency or frequency range that the channel is delivered on. Changes in temperatures can also aggravate the issue.
Check to be sure that all of your cable connections are snug.
Box swaps, box refreshes and multiple box refreshes may not resolve this issue if there is an underlying local signal issue.
Give us a call at 1-800-COMCAST and we can start the troubleshooting process and get this resolved. Insist on a technician visit so that the signal levels can be reviewed and adjusted if necessary. There is no charge if the issue is determined to be with our equipment or originating outside your home.
If connected via HDMI cable, this may be an HDMI handshake issue. One thing to check is to see if you have the latest firmware for your HDTV set. You can check that at your TV manufacturer's website.
You should download that firmware update to a USB drive then install it to your TV set as per the TV manufacturer's instructions.
Please let me know if that resolves the issue.
Thanks for your patience.
Hello, Thanks for your reply. I wish I had an answer for you. When I got up this morning, the SD line was working, after many, many days of utterly refusing to give any sign of life. What the difference was, I haven't got a clue!
Hey, I just hooked up everything but I can't get a "free with subscription" channel. How do I add these to my lineup? Quite annoying.
If thos channels are included in your subscription, call Comcast @ 1-800-266-2278 or 1-800-934-6489 and speak with a CSR about refreshing the box's entitlements. If not, you discuss adding the package that includes those channels with the CSR.

I know this is an old post - but, I think it is important that this information is available to Comcast customers.
I finished the detached garage apartment and I have Comcast Xfinity working there. I added an amplifier-splitter in the garage (where my Comcast service enters my home from a telephone pole). One split stays in the garage to provide Xfinity to the garage apartment. The other split runs about 100 feet up to the attic of the main house where it attaches to another 6 way amplifier-splitter.
Everything (internet and TVs) works perfectly.
