Question about Televison & Video
My TV is hooked up to a ChannelMaster DVR. Often, when I fast forward a recorded program and hit play again, the sound will disappear (picture is OK). The only way to get the sound back is to turn the TV off then on again - or - unplug the HDMI cable and plug it in again. The sound will then return. I initially thought this was a problem with the DVR. But this has happened with two different DVR boxes, so I think it is the TV.

I have had an extremely similar problem with my Comcast Motorola DVR and Sony Bravia with HDMI connection. For months I would lose picture/keep sound when changing from a non-HD to an HD channel. The solution that I found is that there is a setting in the cable box setup that will likely fix your issue. Turn off your cable box leaving the TV on. Quickly press the Menu button on your remote to get into the Box setup. Make sure that 4:3 Override is set to "Off" instead of 480i. I believe this will solve your problem.

I think this has to do with the cable box not liking the encryption thing going on with the sony tv. The cable boxes probably don't understand it fully and therefore you have intermittant problems. I would just use component inputs. Which are analog and no encryption problems. I hope this was helpful. I bet it doesn't happen using a sony DVD Player or a blue ray DVD Player either. Sony, Sony, Sony.....Good stuff...but they have their moments. Let me know if u come up with a fix for this and then i will post it on my fix it list.. Thank you again..GURU JAY

Is the Comcast box digital? and is it a Scientific America 8000 series box?
If so, try unplugging the power to the cable box for a minute, replug and after the reboot see if that fixes the problem...

The problem is your cable box. I know you said you replaced it, but I work on TV's everyday and, sorry to say this but cable box HDMI outputs have serious issues, like no or intermittent sound and video. I have seen customers exchange their cable boxes 5 and 6 times and still have the problem. Your best bet is to use the component outputs of your cable box, visually you will not see a picture difference between component and HDMI when using a cable box. Your other solution is to get satellite; I have NEVER seen an HDMI issue with a satellite box

I encountered the same thing using the HDMI interface on my new TWC cable box (Motorola DCX-3200). After a little bit of research, I finally fixed it by changing the digital audio mode in the cable box using this procedure:
1. Be sure the TV is on and connected to the cable box.
2. Using the cable box remote turn power OFF.
3. Immediately press the MENU key on the remote. The USER SETTINGS menu should appear on the TV screen.
4. Select the ADDITIONAL HDMI SETTINGS >>> menu item.
5. The ADDITIONAL HDMI SETTINGS menu will appear.
6. Scroll to the AUDIO OUTPUT item and select this.
7. Change the setting from AUTO to L-PCM.
8. Return to the main page
9. Using the remote, cycle power OFF.
10. When the cable box is turned on again, you should be good to go.
I realize these instructions are specific to the DCX-3200, but there may be a similar setup option available in your cable box as well.
The problem here is that the cable box is by default configured to use Dolby Digital audio, which requires an additional 10dB of headroom to deal with the boosted LFE channel. If the cable operator hasn't taken pains to set the system up correctly (and most haven't, apparently), the digital audio level sent on the HDMI interface will be approximately 11dB down from normal analog line levels on the HDTV channels. Changing to straight linear PCM sets the TV receiver audio level on the HDTV channels to match the levels on the non-HD channels.
The only problem with this fix is that if you intend to feed a Home Theater receiver that uses Dolby Digital processing with the cable box output you will lose the Dolby encoding feature and be forced into straight 2-channel stereo. For a simple installation like mine where I'm just feeding the TV, this fix works fine. If you have a more complex setup that takes advantage of Dolby Digital features (when it's available in program material), you may have to live with the problem.
For a technical reference on why this happens, see http://www.megahz.com/specimages/Dolby/LM100%20Cable%20App%20Note%2011-05.pdf
Hope this is useful.
