HDMI issues with Comcast HD Box

This t.v. will periodically "lock out" the functionality of the Comcast Remote either when I turn off the set or just leave it on for a while. I cannot change channels on the cable box until I turn the set off and then the remote can communicate with the box. This happens with the hdmi cable connected to the box. I've been turning the set off, then the box, then turning them back on. Is there a setting? I've turned off the HDMI Sync and that seemed to delay the problem for a day.

    I tried the component cables with my Samsung..same problem. This is a real mess. unfortunately I only have comcast or I would change to something else

    remote freezes up and must wait about 5 to 10 seconds to get it to respond. I've had Comcast tech out twice and they replaced the box three times and still have the same problem. They claim it is feedback from my TV but I did not have this problem on the old style component cable box just with the motorola HDMI box.

HDMI Has a safety feature that blocks other remotes from changing things. What a Joke I say. There could be a problem with the feature.
You can push up on the "Settings" button on the remote twice to enter the "advanced" settings menu. There might be something in there that needs to be set.
I found out that if I change the cable box output from HDMI to DVI it will work fine but the picture is not as clear.

I believe its a hdmi and communication problem with you box.The only thing you can do is to go back to component video cables until they come up with a fix.

Lip sync


Vizio HDTV- Lips out of sync

Anyone with a new Vizio E601i-A3 60" or 70" HDTV that is having audio "Lips out of sync problems" with a cable or satellite box.

On Comcast cable boxes (or others), here's what you need to do: FIND MENU for AUDIO or HDMI setup on CABLE BOX or Satellite Box.

FOR COMCAST

1. Turn on TV and have Cable box Turned OFF.

2. Press MENU on COMCAST REMOTE.

3. Go to AUDIO Setting OR HDMI Setting. (On cable or Sat. BOX)

4. Change setting from Auto to L-PCM. (Turn off cable box to exit)

This should resolve any "out of sync" lips to picture after commercials on HD channels.

*This is a handshaking issue from the cable box to the Vizio E601i-A3

How do I connect to Sharp HDTV and Comcast cable


Your dvd recorder only has rca, red white yellow inputs it wont allow you to record in HD, although you can play your comcast box any hd, regular digital through and record. Hook up the comcast box if HD through preferably HDMI if not get one from comcast. The HD box is the only box that allow HDMI, component and regular RCA and some RF out. This way you can play HD to your set but also record through RCA or RF again will not allow for HD record unless its TiVo. Hope this helps

Philips TV HDMI CEC EasyLink tries to control Cable set top box


I finally found a fix to this! YAY. I thought I might have to return the TV. I have the Phillips 42PFL5603D, but should work for other models.

On the TV press menu picture settings---picture---dynamic contrast (turn off) AND active control, turn off
If you have Comcast Moto box: on the Cable box go menu--->setup--->cablebox set up---RF BYbass set to ON
If you have a non-Comcast Moto Box, I'm sure there is an RF bypass setting in the menu. You'll just have to look for it. Another fix was close saying to only turn of the active control, but it took all 3 of these for it to work consistently. The latter let it work for all of 30 seconds.

Need help hooking up TV, BluRay, Home Theatre & cable box


I found that since the Panasonic TH50PZ80U TV has only 2 HDMI ports on the back of the TV, the best solution for me was to use component (red, blue, green) cables to connect the Home Theatre to the TV. I suppose I/you could connect the home theatre to the HDMI port on the front panel, but I don't want cables hanging out the front of the TV (personal preference). Unfortunately, I am no longer able to use the VIERA Link functionality available by connecting all Panasonic components to each other using HDMI cables, but I feel it's a small price to pay for the incredible picture quality acheived by using the HDMI cable to connect the HD Cable Box to the TV. I may yet be able to control everything using the HD Cable Box remote, but I haven't gotten that far yet but I've got Comcast coming on Saturday and hopefully they can let me know if this is possible: let me know if you have a solution.

So here are the components and the cable types used to connect:
  1. HD Cable Box to TV: HDMI cable & Optical Audio cable
  2. Home Theatre to TV: Red, Blue & Green component cables
  3. BluRay Player to TV: HDMI cable
I hope this helps someone else.

No sound on NON HD channels


I had the exact same problem on a brand new Insignia 26 " LCD with DVD. Comcast tech was able to fix it by changing the Comcast box diagnostics. Here is what he did. Using the Comcast remote with the TV on - press power, cable, menu in that order. A comcast diagnostic srceen will appear. Select Additional HDMI options, then audio options. Change the audio options to L-PCM. Press power again to exit the diagnostics. That will fix it and you get to use the HDMI cable.
