Error message !RDK-03004

No Splitters. We have one DVR contour box and 3 other boxes, all connected directly. It only happens late afternoon, evening, never during the day. It will last overnight, and by 4-5 am the system is fine. Makes me think this is a Cox issue, but it never shows there is an outage. You can continue to watch the same channel, but can't change channel or use Contour functions. If you try to restart or unplug system, you need to wait until the next morning for it to reset.

A signal issue is occurring somewhere between your receiver and the Cox server after you've started watching a channel.  When you press the channel up, channel down, or any other button on the remote that requires communication with the Cox server, the Contour receiver locks up waiting for a response that it never receives.  That signal issue is also the reason you're unable to restart your system until it's cleared up.  The same thing would happen if you were watching a recorded program and pressed pause, fast forward, reverse, etc. 

You need to schedule a tech that can check your signal strength, including at the pole.  (Ask for a tech with a long ladder).  You can't schedule it for evening hours, so try to schedule it for as late in the day as Cox will schedule an appointment.  

A ladder not needed, as all our connections are under ground. Again tonight at 7:30, it stopped responding. I can see why people use streaming. This is ridiculous. I’ll schedule an appt, unfortunately as we work until 6 this Cox issue is going to cost me work time. I’m just about over it. 

Exactly! It’s a Cox issue, but no one can figure it out. They throw things at the problem to see if it will stick. Tech visits to the house say the signal strength bot outside and inside are fine. It didn’t happen while they were here. Usually happens in the evening and the weekends, so when use will be busy. Maybe they need to check the signal strength at night. If I call for help they tell me there is no outage, but can’t reset as they show my service offline not responding. Yet internet is fine. I just want it fixed. I want to be able to use my service with no interruptions. All my remotes are less than a week old. Tech says the signal from the remote to box may be the problem since I can’t restart my TV box with remote. Only by unplugging. 

As I said in an earlier post, remote commands require a response from a Cox server.  If you're having a signal issue, the response may not be received.  That's why your remote doesn't always work.  Was it a contract tech that said the signal from the remote may be the problem?

Do you know any of your neighbors well enough to ask them if they're having similar issues in the evening hours?  Because it only happens at night, it sounds like a main line issue that could be affecting your neighbors too.  If it is, ask them to contact Cox, if they haven't already,  That could help Cox identify the problem which could result in it being escalated and the solution being found. 

I will be calling Cox to have them replace the box going into the house. Just spoke with my neighbors and they had the same issue a couple of months ago. Cox finally replaced the box with the cables going into the house. Their box is in their attic, ours is outside. She said that fixed  their problem. After 20 years I’m sure ours needs replacing. 

I was waiting a few days before reporting since, the first tech "fixed the issue, but within 3 days, it went back to doing the same error message.

The second tech did fix the issues, or at least it's been 6 days since the last error message. It has "restarted" itself twice in during that time period, but no error message, and came back on within 5 minutes. The second tech checked the line at the road, the line at the box, the inside lines and all the boxes and determined it was the line from the road to the box, which was buried - he put in a new line and over the ground and Cox buried it within the week. The last week we just look at each other and can't believe we have a working cable system. Didn't realize all the stress it put on each person in the household. On the upside, both my mom and husband learned how to stream on their televisions, as that is all we had for the month.

Now to call Cox and see if they will credit some time on our bill, since we did not have cable consistently for the the last month.

Glad you were able to get it fixed.  Thanks for posting back.
