Does this cable work between Comcast HD receiver and HD TV. I bought one, getting no signal message

Yes. Mine seems to work with a Comcast HD receiver. And I even have a splitter going in between.

HD receiver and HD subscription from Directv, does work. The real problem with most systems is the antenna is not able to be connected to a strong signal. Amplifires may help, but is only a poor substitute for a good signal.

I had no luck. I bought it and got no signal. Even did a continuity test and seems as if there is no connection. Good luck but I think this is a novelty. No actual way to convert technology.

It didnt work with my computer, I was unable to send any video signal to my PANASONIC HD TV. I try changing several resolutions of my computer, to look which was compatible and was a fiasco. Take care,

Hey this is Nina I am not sure but give it a try. Plug it in the modem and see if it works and it not, plug it into the wall using comcast service. It should work either way. Nina

This cable only sends signal it will not receive it. As in you can plug it into the Xbox to send signal to your tv box. Hope I helped..

Your HDMI cable may not send the information, use one with audio return and internet capabilities. If you have it hooked to a cable or satellite receiver they (nearly all Directv and some others) cannot send the required signal, it's not the splitter, rather it's the unit hooked to it. If your signal is coming from a DVD, Blue-ray etc it should work. Check to see if the receiver is showing PCM or something else as an input source signal. The receiver should be able to decode the signal from the source via HDMI as long as the signal is provided to it at the input. Just a side note, if you have a DVR or other device as a source run the splitter directly from this device to the splitter and then to other devices such as a second receiver or a TV. If you run it to the TV then to a receiver or other device you may run into a problem as many TV's do not send the required signal out (even if it says the TV does or does not address that issue). Good luck, I know the units should send the signal but, you can email J-Tech if you can't find the problem and they will help, or send you a replacement if it is defective. However, I have several friends who have purchased the J-Tech on my advice and ALL their minor problems dealt with issues other than the splitter. On one system I had to turn everything off and hook up the connections then power up the connected devices then the splitter; it was an ARC problem but, that seemed to cure the problem. Again, good luck.

I've not used this for HD-SDI but I have used this cable to handle HD Cable Services and Over the Air(HD) signals inside our house with no issues for me. I've also used it as the internal for a Cable Modem Internet connection as well.

I'm no expert, but I doubt it would work as comcast is on cable and not DSL. Two different systems I beleive

I am using coaxial to transmit HDTV and it works. This is just like using coaxial from your cable box to transmit HDTV signal to your HDTV. HDMI is needed when you are using a laptop, etc.

It will work work for either dish-dtv, as for HD "I don't have a receiver" but my understanding is the receiver is what converts signal to HD. All the dish does is capture the signal the receiver does the rest. Hope this helps.

The tv works with Comcast cable but will not turn on and off with the Comcast remote. Need to use the tv remote to turn it on and off.

Make sure you are on the right component input. If that doesnt work then try it on another tv. It will let you know if the cable is bad or tv input is bad.

Yes. Mine goes from cable box HDMI output to digital TV monitor's DVI input. Works perfectly for HD TV.

If you have a digital receiver, it will work, regardless as to whether it is an HD set. If you have an analog set, you will need a digital converter to run the antenna through.

It didn't work for me. No signal at all. I have since found out that you need a analog to digital converter to convert the VGA (analog) signal to the HDMI (digital)signal. I may be explaining this wrong, but something like this. Regardless, i had to order a totally different cable with a converter. This cable did nothing for me.

No HD input. Only CATV cable in for OTA broadcasts. There is one HD output that goes to TV. The only other TV output is for standard TV RCA video and audio cables. If your TV has multiple HD inputs, you could get a CATV splitter to enable watching HD video from the Comcast box and record HD from the HDR5710.
