No Digital Signal to TV

Hello! I bought a Sony Bravia 40 inch 1080i and originally installed it with the coaxial cable to the digital dvr cable box and it worked fine (horrible picture though). I then bought the HDMI cable, connected it to the back of the TV and to the cable box and I get a 'no digital channel found' meesage. Any ideas?

    Tv says no signal after plugging coax from comcast box into tv. Tv is brand new tonight and plays the 23 digital channels fine when hooked directly to the wall, bypassing the cable box.

Make sure you have Tv on that particular HDMI input .I believe video 6 or 7 .if you do check menu make sure that input is not blocked. or you might want to try the component outputs of cable box and connect that to a component input on tv to see if that is working,,i have seen these tv HDMI input board bad..lets hoe this is not the case..

Can the sony bravia home theater system be surround for both dvd and tv?


Strickly speaking about the audio:

The unit has digital audio in on 1 each coaxial and digital connectors.

Most DVD players have digital audio out in either a coaxial (RCA-looking) cable or optical cable.

Consider this: your TV is not a Source of audio (or even video, if you think about it). You probably get your programming from a cable or satellite box, Its audio should be available digitally.

If your DVD and cable use DIFFERENT types of digital audio sources, you're in luck. Attach each one to its compatible input on the Bravia. If you only have two optical outputs you can only attach one at a time.

If you have only two COAXIAL digital audio sources you CAN combine them into a single digital input on the Bravia by getting an RCA-splitter cable to connect them both to the one connector. It will only work if you leave one source dormant or off at any time you're monitoring the other source, otherwise you'll have two digital 'converstions' going on with the Bravia at the same time and it won't be pretty.

I have a sony 40 inches bravia flat screen hd and


Could be the decoder:

1. unplug the TV ans wait a few mins.
2. If you have digital cable box or dish tuner reboot those as well (likely your issue)

What you have is artifacting what that means is tiling garbiling and freezing this happends when the data in the digital stream just stopped hence Frozen.

Try those things rule out your cable tv box first or your sat box, if this is OTA over the air your antenna.

1. Try DVD's if it happends during a DVD you do have a decoder issue if it does not you need to talk to your cable tv or sat operator.

So you got 3 possiabilites here 1. the worse Decoder, 2 cable company or satalite provider, 3 your antenna is in the wroung position.

I sure this will help.

Wiring problems


Not certain if HDMI can be used in a setup like this. I'd try it from the home theater (HT) to the TV, and other wiring for the other components.

For video:
All of these should have component connections (Y/Pr/Pb). You'll only need the video cables for each device:
  • Video out from cable, HT, and combo player.
  • Video in to TV. Your choice of inputs.
For audio:
Hopefully, the two output devices (the combo player and the cable box) have digital audio (fiber optic, or RCA coaxial). Otherwise, you'll only get stereo sound. VHS is stereo only anyway.
  • Audio out from cable box and combo player.
  • Audio in to HT.
The TV won't have anything to do with audio in this setup. Alternatively, you could try hooking up all inputs to the TV, and connecting audio out from the TV to the HT. Works best if this connection is digital, for surround.

Sony Bravia Dav-HDX279W and comcast HDTV Cable box connection.


Like above, use an optical connection (need fiber optic cable) or a coaxial connection (single RCA cable). HDMI might also work, but I personally haven't checked. Connect the audio outs from the cable box to the audio ins on the home theater. The TV will only need a video connection from the cable box, as well as one from the home theater (for DVDs, onscreen menus).

This discussion can help you set up the universal remote.

Sony Bravia and Comcast MY DVR Not Working Now


Greetings...

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...

Try plugging the coax directly into the T.V. or from you VCR or DVD player then to the TV. The bravia sets also have various picture mode settings as you will discover when you go through your manual. Cable boxes or splitters can cause problems also is they are not of good quality. I love my 40.
