I have a 46" Sharp Aquas LCD with HDMI inputs, however, I cannot get a signal from the Cox converter box although the HDMI cable is connected. I can get the signal through the componet cables and off the antenna. I have used two separate HDMI cables and neither work. Contacted cox tech and they said it should.
When I scroll through the inputs on the TV, it will not go to the HDMI inputs -
Am I missing something in the settings or does this indicate a faulty TV?

Re: Cannot get a connection with HDMI input
When the tv won't scroll to the HDMI inputs, it means that the tv does not detect a signal on those inputs. This either means the tv has an issue and can't receive an HDMI signal(very unlikely) or there is no signal being sent from the source(converter box) The first thing I would do is unplug all output connections from the box except for the HDMI output and see if this gets rid of your problem. If not, I would be more inclined to think you have a problem with your converter box than with your TV. You could also try using the HDMI ouput of a DVD player if you have one.

Cheap way to get around it is to get a converter that takes your HDMI signals and changes them to other format such as composite signals that may be accepted by your set. If your set has other types of video inputs you might want to check this out. Otherwise, a trip to repair shop is in order.
Have you tried a different HDMI input on the TV? Are you sure you've selected the correct HDMI input? Make sure there are no component cables connected to the cable box. Occasionally that will disable the HDMI output.
im not sure but could it be a comparability issue with the device and the wake up signal from the device to the tv? android systems use a Linux based file system, so the problem may be in the tv's input settings. hdmi input from the device to the tv. and then go to tv input mode and see if putting the device in another hdmi port doesn't work.
there is a possibility that there might have been a power surge sent over hdmi into the hdmi board on the tv. if on your model the hdmi board is seperate from the sine board then youll have a cheap replacement if not its gonna cost you roughly 300-400 is my guess.
I have a similar problem. The Sharp TV aquos appears to be shutting down my blue ray player and dvd recorder when connected via HDMI. They work fine and never close down when I connect them via the rca cables either single video connection or a composite 3 cable rca lead. I have 3 HDMI inputs on the tv and the problem occurs on all 3. Any suggestions?
If you want CC all of the time, this works well. But since you must power-off the cable box to change the setting, switching CC on and off is a real pain.
Your set-up is similar to mine (Sharp Aquos 46" and Comcast DVR). I have the composite output from the cable box going to a DVD-recorder and on to the TV. Whenever I need CC (usually to catch some mumbled dialog), I just rewind the DVR, and switch the TV input to the composite input. Then I switch back to HDMI to continue watching in HD.
Digital inputs on Aquos TV's are "always on," usually the HDMI inputs and DVI inputs. As opposed to analog inputs 1, 2, or 3, are only activated once something is plugged in. Try plugging in another HDMI sources into input4 or 5, if its still not working, the TV needs a new Main Board. Try calling Sharp 1-800-237-4277 and locating a local service center in your area.
