    I noticed while watching AMC that the picture tends to get a purple hue often, then suddenly corrects. Has anyone seen this happen before? I don't notice it on any other channels and it happens on my other TV with an S3 connected.

    Signal strength is 100. SNR 36.

    Here's a (badly taken) video sample. You can see the background to the left of Walt get purple and then correct suddenly.

    Are you using component (Separate RBG RCA cables) connection to your TV? If so, check the connections or suspect a bad cable. Purple would suggest a weak or missing Green signal. However, sync comes along the green cable also, so if that is completely disconnected you get a black screen. A weak Green signal could still provide sync but make the picture somewhat purple, I would think. Easy to tell: just wiggle the cable near each end.

    I don't see this effect on any channel, including AMC with my Tivo HD.

    Thanks for the reply. Running HDMI, no component. I wonder if it's in the cable company side.

    It could be your TV acting up. How old is it?
    I would say to temporarily put your source directly to the TV, bypassing the Tivo.
    This will, at least, help you narrow down which device may be the culprit.

    Try a different HDMI cable to see if the problem still occurs. I had a similar issue, where the color would get all whacky and I'd have to "restart". I'm all OTA, by the way.

    Nah. It's HDCP or something else going wrong on the HDMI handshake. That's what I get with my Roku when I have 5.1 sound(?) enabled vs 2 channel stereo.

    Check the HDMI cable connections and try shorter cables. It won't fix it. :p

    Going to component cables will fix it.
