Significant Pixilation and Audio Loss with Cox Digital TV

If we can read good signal levels between the headend and the receiver but you continue to have issues, and resetting the receiver doesn't fix them, then there may be an issue with the receiver itself or there could be a problem with the connection from the receiver to the television.

The simplest way to track down whatever the cause may be at this point would be to schedule a service call. If it's a problem with outside signal or any equipment we own, then there's no charge.

Kip, the sigificant pixelation and audio loss ONLY happens on Saturday night during prime time (i.e. starting shortly after 8:00pm). It NEVER happens ANY OTHER day of the week or time. Are you still going to claim there is an "issue"? The fact is, your service gets overloaded and paying customers get an inferior product. I know you are not allowed to admit this is the real issue, but it's obvious enough to me.

We'd be allowed to admit it, if that was how digital cable worked. However, digital cable doesn't use bandwidth like you seem to be thinking. Digital cable television is a broadcast system akin to an over-the-air antenna or a satellite, just more reliable since it comes over the closed hybrid-fiber-coaxial network. There's no more demand on the system at 8PM on a Saturday than there is at 4AM on a Tuesday. Your neighbors turning on more boxes connected to cable can't cause quality loss on digital cable any more than your neighbors hooking more TVs to their aerial antenna could cause quality loss on your aerial antenna if you had one.

So yes, I do still think you have an individual issue.

Don't know if this will work for you, but I called Cox about the same problem (pixilation, image freeze, sound loss) and the technician told me to disconnect the cable from my tv and wait 10 seconds and reconnect it, and it worked!  At least, for the moment. Image is good, sound good.  Try it; it might work for you.

I'm having the same problem. It happens on just about every HDTV channel and on both TVs. This only started after I "upgraded" to HDTV... I've had a tech out. He checked every connection all the way down to the pedestal. I have replaced the HDTV DVRs after the drives died. According to the tech the signal levels are fine. I was able to show the tech the problem as it happened, I even showed him recorded shows where it was happening. He also stated that he has similar problems as well as being called out to other houses with the same problem. The tech said he would ticket the maintenance group..  This was almost a month ago. The problem still persists, it's incredibly irritating. I pay over $240/month for phone, internet and TV service. The phone and internet are fine, TV is useless.

The last technician appears to have just addressed a single receiver equipment failure problem.  It may be beneficial to setup another visit to see what is going on.  At least one of the boxes appears to be reporting marginal signal issues still.

Can you tell me the last 4 numbers/letters of the device with the marginal signal error?

Try looking for last 4 of S/N HNGX.

Following May 10 post - we have the same problem but only with the TV running from the DVR HD box, not from the standard box.  Watched the same movie this morning from both TVs but only the TV fromt he DVR HD box was having issues; the other TV running the movie without issue.  So what's the problem there?

Also receive message while trying to access HD channels through DVR HD box saying the HD channel is temporarily off air??

I have the same problem. A tech guy came out like once a year for the last three years. Says it's signal drop, could be a bad line in the ground in the neighborhood, etc, etc. Says he will submit a report, but nothing ever happens. Tired of the pixeling and freezes. We record programs, half record right, half are pixeled out and freeze. I just bought a 3d tv. Doesn't seem like cox has much 3d. One channel, but you can't get much info on site about 3d. On demand has like 4 boring 3d programs.  Between pixels, freezing and internet going in and out 6 or 8 times a day, 3d doesn't seem to be much at cox. I am checking out directv, and like wow, on 3d. Going to direct will also solve the pixel and freezing problem, and internet going out so many times a day. Cox is telling everyone the pixel and freezing is an Individual problem, but it seems like everyone is complaining about it.

kip k seems to be quite arrogant and self righteous in his answers. I really enjoy the answer to pnwson and the elaborate show of tech knowledge on how digital cable works. Knowledgeable, Yes, but the condescending tone was interesting.

The signal levels being reported back by that box are terrible.  I would check all the fittings/cables to the box to make sure they're all hand tight and make sure there's no obvious cable damage.  If that doesn't improve things it may be necessary to setup a service visit to troubleshoot further.
