I have this error also.
on 3 tv's
tried everything, sent new signals to activate, unplugged for 30 seconds, and pressed the power button to reboot.
many times in different order.
I do still have internet perfectly.
Got a tech on the phone earlier this morning.
He said, "There is no outage in your area, but there is a degraded signal that should not affect your tv."
and he could not ping any of my boxes.
I inspected all of my inside lines, the only suspcious thing I found was the splitter "EV01-5-U/U" is making a loud
noise simular to a transformer hum. Although a green light is lit on it, which is supposed to indicate all is normal.
Any help would be great.
I have had comcast for less than a month I am having the error RDK-03003 problem on all TVs in the house. I have tried everything suggested to solve the issues and also rebooted the set top box. Anyone else find any solutions?
Same here, Sunday night it goes out. Tried power cycling. Called and sat on hold, woke up on the couch next morning with a dead battery.
Came home Monday and still not working.
Comcast why doth thee suck so bad?
I just got my comcast service in yesterday. I have this RDK-03003. I'm already fed up with the unplug and reboot. How is it fixed? I just got this yesterday!!!!
I got lucky by calling 1-800-comcast and asked for technical support. They were able to resolve my issue.
