Hooking up new HD TV with digital HD cable service

Have new HD TV hooked up and connected to HD DVR digital cable box (and service through Time Warner) and new home theater system. Used "monster cables" and everything is working, but the picture is awful on all channels, regardless of HD or not. Even the radio sounds "snowy." Any ideas of where to start looking for a solution? We're new to HD.Thanks.

SOURCE: TV only will play HD Channels

This must be the setup for your TV box. Contact the support for your TV box.

Normaly, the TV should auto select the proper operation mode.

SOURCE: 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.

SOURCE: sony bravia 40" hd lcd gets picture but no sound from cable box

You will have to go into the settings of the hd box by pressing the settings button twice and then scroll down to "audio digital out". chances are that it is set to Dolby Digital. If you right arrow over you can then set it to HDMI. this should bring your volume back. Hope this helps.

You don't record from TV, you record from cable so cable needs to be hooked up to input on VCR.
If you don't use cable box you would hook cable to VCR then out of VCR to TV. If you use cable box then you need to connect Video and Audio outputs on cable box to Video and Audio inputs on VCR and switch input of VCR to Line input.

Have you tried using component cables instead. One of my Time Warner cable boxes did the same thing using HDMI.

HDMI cable hooked up, now CLOSED CAPTIONING is stuck on!

It has got to be the box. I would try to contact Scientific Atlanta if any way possible. The TV doesn't choose what inputs it shows CC.In other words, it would show it on all Inputs if it was the TV. Good luck and Thanks

Close captioning on HDMI

The TV will not display closed caption with HDMI input. It must either over-the-air (antenna) or composite input for the TV to manage CC.

To get CC with HDMI from your Comcast DVR, you need to configure the cable box. Instructions can be found here:

If you want CC all of the time, this works well. But since you must power-off the cable box to change the setting, switching CC on and off is a real pain.

Your set-up is similar to mine (Sharp Aquos 46" and Comcast DVR). I have the composite output from the cable box going to a DVD-recorder and on to the TV. Whenever I need CC (usually to catch some mumbled dialog), I just rewind the DVR, and switch the TV input to the composite input. Then I switch back to HDMI to continue watching in HD.

I was given this tv I need to connect cable

your t.v will hook up directly to cable. if you are asking how to hook to a digital box then you can hook it up the same as you had it hooked on your previous t.v. but if you want to get high def channels then you are going to have to take your digital box back to Time Warner and swap it for a high def digital box. or you can just call Time Warner and have a technician go to your house and swap/ hook things up for you. Hope this helps you.

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.

Connecting HD cable box to DVR too HDTV

When I hooked up my HD cable box using an HDMI cable, I had to go into the cable screen menus and select HDMI output. You may have to do something similar when using an S-video cable. Your DVD recorder doesn't seem to have an HDMI input, so you'll have to use the S-video or (worst case) composite video (red, white, yellow cords). Your cable box may also be scrambling the signal so that you can't record. That may be why you can record by bypassing the cable box.
