Signal from HD cable box occasionally gets scrambled/black out
The signal will either get scrambled or completely black out when a special visual effect is shown on a channel, or certain types of commercial. I tried changing HD cable box, but that was not the problem.
I have had the same problem with Comcast and Dish Network HDTV receivers (center mode icon comes on then screen blacks out for a couple seconds - happening more often during commercials). As suggested I changed the video resolution in the set up menu of the receiver and did not experience the problem any more.
Try removing 1080i from your list of available video resolutions in the setup screen of the Plasma display. If you are using a HD satellite receiver, check the LEDs on the front and note if the device is slipping into 1080 mode when the probem occurs.

Tries tv and box unplug,replug back like an hour later.The box now should have it software updated and tv resetting itself.Tv shoud be working again.Still have the same problems,tv the cause main tv Tuner signal board is dying.Get an estamate from shops and get it repair.
Are you connecting these devices to the ColorStream inputs?
If so you will need to set the output settings on the DVD player or your camera to 480i. You have an HD capable TV but it is old technology and is not capable of handling the signal levels produced by HD equipment these days.
Look at the menu options on your equipment and most of them have the ability to put out the lower level signal or just hook them up using the standard yellow/red/white inputs. Hope this helped.
More often than not the problem is with the Cable co. They ALWAYS blame the tv. I have had many many problems with the signal quality coming from that co. Here is the most likley cause. The cable signal is probably very Weak. This can be caused by a weak signal coming from the cabls co. or a bad cable inside your home. The age of the cable can effect the signal quality.Note: The cable co is only required to provide a Digital signal. Some companies allow free HD signals and some charge for that signal. The correct approach to this issue is to get with the Cox and ask the if they provide free Hd channels without a box. If they say no then you will have to get a HD cable box to watch HD programs. Themn if they say yes then you need to ask them to send out a tech and test the signal coming from the Head End all the way to your set. If the signal flucuates then you will get inconsistant scanning results.
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.
I had the same problem
you have to set up the componant on DTV.
the signal my be hd 1080i and the only connection with componant that can support this is the DTV port.
the other componant connections only support 480,
if you are getting signal of the proper strength and quality the cabling is good.the problem is the box trying to decode the signals.a lot of signals are encripted and have to be decoded by the box.if the box is not responding fast enough you will see bloches on the tv.if you see scrambled channel you are not payinfor that channel.and if you are paying for a channel and it comes up scrambled your box is not working correct.get your company to upgrade the box.
Saying that the problem is with your TV doesn't make any sense since your TV is fed from the cable box. Your TV doesn't know one channel from the next. If it had a problem it would effect all channels. You may not have enough signal to the INPUT of your cable box due to a problem on the pole or at your house or both. Insufficient signal can cause some digital channels to not get decoded properly by the cable box. The lower channels will show noise symptoms such as what you describe but they won't crap out altogether like the digital ones. Have a cable tech come out and measure the signals.
Do you have splitters in line with the cable anywhere? If there's any way to beef up the amount of signal getting to the cable box try it.
i know this problem, happened to me with the comcast Motorola HD receiver box. The key is with the setting in the cable box.
Switch on the TV.
Set the channel to normal tuner channel 3 or HD input.
Turn off the cable HD box.
Press the Menu Button on the Cable box or the remote.
You should see a Menu.
Use the cursor keys to navigate
The default setup is also one of the option, Right click on your cursor keys acts like the computer keyboard enter key and applies the change.
The default setup is 16:9, the shacking would happen if you have set the picture type to "PAN SCAN". change it to either 16:9 or 4:3 Letter Box. The shacking should stop.
Hope it helps.
