On most occasions I've tried to carry a vcr that has HDMI output on calls with this symptom. In most cases it has been an error on the part of the cable equip. However, most manufacturers including samsung have firmware upgrades available which make product compatible with more types of equip. Call 1-800-samsung for customer service or try other unit with HDMI out. Hope this helps.

CAN HDMI BE REPLACED?


Yes an HDMI port can be replaced, but more likely you will need to replace the entire board the HDMI resides on. Ports are typically just conductors, ie wires. It's probably not the conductors that are messed up, it's more likely the circuitry that decode the HDMI signal that is messed up. Check your cables and whatever you're trying to connect on another TV with HDMI (perhaps a friends if you don't have another TV with an HDMI port) and make sure your cables and cable box are both operational.

Get a component video cable (blue, green, red) and a separate RCA audio cable (white and red) if your cable box has a component video output and the TV has a component video input.

If your cable box doesn't have the component output, you will need a converter to go from the HDMI to component video. Something like this: http://www.hdtvsupply.com/hdmi-to-component.html . There are other converters available if your TV has some other inputs available.

A cable that has an HDMI M on one end and a VGA M on the other will not work. HDMI signals from the set top box are a digital signal. The VGA port on the TV is set to read an RGB analog signal. (Similarly a component to VGA cable would not work since the RGB and PbPrY are not compatible.)

I hope this helps.

Please post the Brand/Model of you cable box and that of your TV so I can provide you with an answer that is more accurate than a guess.
The guess is, since we are talking about HD I will assume that your cable box has an HDMI connector and you have also an HDTV with HDMI connector somewhere in the back. In that case you will need an HDMI cable and that will connect both Audio and Video signal. Then you just set your input source selector on your HDTV to HDMI (if multiple select the number of the one where you connected the cable box), and you should be getting picture and sound.
Now, if your HDTV has no HDMI input then it will be very likely that you will have to use a Component cable that is ONLY for the "video" signal and looks like 3 RCA connectors color coded as Red, Blue, and Green. You will need to get and additional cable to feed the "audio" signal from the cable box to the HDTV using a stereo cable with RCA connectors which are usually color coded as RED and WHITE.
Note: This setup although better than nothing, is somewhat defying the purpose of having HD. The signal in Component connections are analog (although of better quality than Composite i.e. the old single video cable color coded as Yellow). The analog signal is limited by design and will get you only so far in your HD experience. The HD signal is digital and will yield the highest quality in both audio and video.
Assuming you are paying extra for channels that are HD then it would be worth it to do some more research or ask for help to one of your savviest friends so you can get the best gear and results with the least expense ;)
In all cases you should be able to see the programs and hear in stereo, your experience will vary as: - Your video signal may be a 480p instead of getting a higher 720p or 1080i. - your audio signal although some movies are available in 5.1 surround, not having a surround system will just give you the stereo sound from the TV.
Either way is your call how you want to experience your media... if you like to read more on the subject a quick start could be the TV glossary at crutchfield for instance:

Best!

It is up to you use the HDMI input so you can select it from your remote, notice one may be an output but the cable box hdmi device will plug into the box and the other end plugs into the hdmi cable connector. then select from your remote or your tv that hdmi connection to recieve signal, and set the remote to work with the TV and the Cable box, if you need more help post here and if this was helpful please rate.

Part of your message I cant really understand but if this helps you out at all, Try to get a new box from your service provider. I have been hearing other people having problems losing signal from HDMI enabled cable boxes, if it doesnt work then just try your standard Component cables, they can still output 1080p from an xbox 360 and thats better than the 1080i you will get from cable. Some TV's just dont keep the power flowing to the HDMI reciever for some reason or another. The component cables shouldn't give you any problems though. Good luck.

You need a audio cable for sound. HDMI cable is only for picture. I use the comp 1 plugs myself, better picture. I found with my TV that the HDMI cable is only good if you have a digital box for it. You can also use the plug to hook your computer to off your graphics card and watch downloaded movies on.
