TV pixelating when it rains

For the last 6 weeks my TV pixelates when ever it rains, even a light amount of rain. What would cause that? It is happening to both my TVs each TV has a DVR one DVR rather old and the other new (both from Comcast). The only thing that has happened is about 6 weeks ago we had a violent storm that knocked branches off the trees.  One branch was against the line from the pole but that branch has been removed. And if the branch caused it why does it only effect the picture on rainy days? If the cable from the pole was damaged, cut open by the branch would that explain why the pixilation only occurs when it rains? Thanks for any help.

Re: TV pixelating when it rains

Chances are pretty good water is getting in somewhere or there’s already corrosion possibly causing the pixelization. The water is drying up on non rainy days. Squirrels love the cable jacket too. Have a tech out to check out your drop.

Re: TV pixelating when it rains

I want to call and have a tech come out to examine the line to repair/replace it. However since the problem only occurs when it is actually raining, when the rain stops the problem stops, how would we know if the repairs worked?  Is there a test the tech would do that would show him where the problem is so a fix done on a sunny day would have a high probability of success? If not, is there a way to get on a list for a tech to come out on the next rainy day to see the problem and then fix it while it is still raining? In short how do a get the best chance for this problem to be solved?

Re: TV pixelating when it rains

There’s no such thing as a rainy day list. There are multiple signs of corrosion or water present that a tech looks for, both at the pole and up at your house. That’s the fun of troubleshooting, you won’t know it’s fixed or not until conditions are replicated. Make the call

Re: TV pixelating when it rains

So to try and resolve my existing problem I swapped out my old DVR for a new DVR but the issue still exists so I will be setting up an appointment to have a tech come out and check the signal level coming into the house and check for any damage to the cable coming into the house.

Re: TV pixelating when it rains

Problem solved. I guess a number of customers had similar problems because Comcast sent out a tech with a cherry picker to check the lines and he found a broken box two telephone poles away and now all channels are working perfectly. Thank you Comcast.

 

I had asked the tech to look at the line coming from the nearest pole to my building where the tree branch hit the line when we had a big storm 6 weeks ago. He said he would take a look but then left without looking at the cable. Fingers crossed that when we get rain next we won't have a problem. But for today all TV channels are working  and the Internet connection is as fast as it has ever been.
