Cisco 4742 HD receiver is slow to render picture and sound

Often when changing channels on the 2 year old Cisco 4742 HD receiver, there is a noticeable delay of approximately 3 seconds between when the channel is selected and the picture/sound is completely rendered. In fact, sometimes the picture for the newly selected channel is frozen with no sound. It is connected to a 3 month old Samsung HD 1080 LED TV via component video cables. Once the picture has been completely rendered it is beautiful and never seems to miss a beat. The receiver has been power cycled and the boot process took several minutes. Yet, the issue remains.

Hi Robh, what channels are affected? Is this a new issue or has it always been like this? Does this happen on all TV's that are connected to cable boxes? Is the Cisco 4742 connected by a splitter?

All channels are affected. We only have one cable box and the issue has existed since we moved the box to the new television. I don't recall that being the case on the other TV as that set was rarely used. The run for that TV is directly attached to the splitter at the demarc. While the cable run the box is currently connected to goes through multiple splitters on the exterior of the house. The drop is about 15 years old and I wanted Cox to replace it last summer while the weather was warm but it didn't happen.

Hi RobH,

We can reserve an appointment for a technician to investigate and troubleshoot the signal. Have you attempted to swap the Component wires for an HDMI cable to see if there is any improvement with the response of audio and video?

Thanks, Dustin. I expect to have a lot more troubleshooting results within the next 24 hours and then we'll take it from there.
