Default Problems with Comcast cable TV signal

We had some bad weather in my area this past week and I was having problems with my Comcast cable. The picture on most of the HD channels would pixelate badly and the sound would go out. Some of the HD channels would work fine. I called
Comcast and they were going to send out a tech today between
4-7. I turned the TV on in the morning and all the channels were perfect. I called to cancel the service call and asked if they knew what the problem was and of course they did not. This same problem happened last month during bad weather. It was fixed
on there end without sending out a tech. My question is
does anyone have any idea what they did to fix my signal?
Like I said before I asked the rep on the phone and they
had no idea what was done to fix the problem.

We don't have HD yet, but one of the older digital boxes. We only use it because we subscribe TV5 - the French Channel for my wife who is taking french. We never watch anything outside of what the old Sony can get under channel 100.

Anyway, we were having a similar problem for a month after having worked fine for a couple of years. Did not seem to be weather related. Eventually had a service call and the tech insisted it was probably the three way splitter I had installed weakening the signal. He put on an amplifier (one time charge of $20) and it hasn't come back, so I guess he was right.

It could be that water is getting into the connections somewhere. If you have access to the connections into your house, it might be worthwhile to unscrew the coax and screw it back in to check tightness, and then maybe weather proof it a bit with some tape.

Unhappy Pixelization probs

I too have problems with Comcast pixelization and a freezing of the current frame and no sound. This tends to happen more at night, and a ton on weekend nights. I wonder if it has to do with when there are a lot of people watching TV. Weather also has an effect. It is frustrating as heck to have this happen right at a point when you are hanging on to the next words out of someone's mouth, and it freezes up! I too called Comcast, and they gave me the same response of having me disconnect and reconnect my cables. I didn't waste my time, since my TV in my bedroom does the same thing, as well as many other people who complain about the same thing happening. How do we resolve this?

I had a similar problem with Comcast. Whenever the weather was wet or windy I would experience it. I felt that my wire from the pole either had a bad spot in it or was not connected tightly at the pole. When Comcast came out they in deed detected a diminished but fluctuating signal level and they changed the wire from my pole to the house and the problem was resolved.

I have all kinds of trouble with my HD channels. They break up at times and no one at comcast can do anything to help. when you call, you get a different answer every time. i've even had them flat out lie to me over the phone and chat.

they once told me on the chat that they would not provide me any sort of immediate credit on my bill for the trouble. BUT they were taking names and once everyone's problem was resolved, they would pass out credits then. LMFAO.

I had similar issues with my old motorola hd-dvr (DCT6412); swapped it out for a new one (DCH3416) and haven't had any problems.

I had a C-Band satelite for years and always had the same problem when there is weather thats because the signal has to come through the weather thus its weak pixilization occurs when its trying to fill in errors in the signal. Cable gets their signal via (like everyone else) satelite in bad weather you get some pixilization sometimes you dont have any weather but the source has bad weather. High wind has alot to do with the receiving dish (or sender) moving or swaying even slightly can cause it to drop signal or weaken it knocking it out of alignment. Now I have a thought on your rain problems you might have water leaking into your cable box or down the street it could go underground somewhere and be exposed to moisture. See if your neighbor has the same problem if so I would say your got conditions somewhere out of wack. However I would not complain about it until it does it again consistantly because if they find no problem Comcast might charge you for the visit especially if they have come out a couple of times. I know its hard to get them to come out during an actual problem condition as it takes days to schedule you in but if its consistant then plan ahead of a rain storm so they come the next day or better yet during the storm!

Comcast lie never! Man all services lie to you its foolish not to expect it. Ive gotten so good at detecting BS. My favorite is when they tell you to unplug something for 60 seconds LOL! to reset it. We all know 3 seconds is plenty of time for any reset. When they say 60 I know they are just reading off a screen and have no clue what they are talking about. I love the blame game if they find out you have some extra components in the loop of the problem instantly its that component thats causing the problem. Or if your not renting THEIR equipment the problem will never be fixed until you do. This happens alot with Comcast internet if its not THEIR modem its not their fault.

There are ALOT of things that can affect your service. If your having service issues during increment weather and it goes away when the weather clears up then its most likely a bad fitting or drop. Again there are alot of things that customers do that can affect service. Those cheap Wal-Mart gold RCA splitters you install to save yourself money and get an extra line to the kids room actually lose signal and cause problems to the other tvs in the house, you should not only expect to pay for the service call, but also pay to have the tech replace it with one that is up to local cable spec.

It's kinda funny that in the COMCAST ads bashing DIRECTV and DISHNETWORK they say - COMCAST TV service doesn't go out in bad weather like DIRECTV and DISHNETWORK does.

Read your "Terms of Service". Most have tiny print that is hard to understand, but yes, they can "throttle" your download speeds. This seems to be happening more and more as users are using more bandwidth, mainly filesharing. GL
