This has been very frustrating!
My TV is around 50 feet of cable length from my receiver and it would be very difficult to run any new cables. I had a uni-directional HDMI cable run from my receiver to my TV fail this summer. To future proof I did run four cat 6a cables though. My TV is a little older and does not have Audio Return Channel and it would be very very difficult to run an optical cable from my TV to my receiver.
I purchased an inexpensive digital TV tuner to replace what I THOUGHT my cable box did in my setup.
Mediasonic ATSC Digital Converter Box with Recording / Media Player / TV Tuner Function (HW130STB)
Digital tuners take the antenna coaxial and have an HDMI output to the receiver. The digital TV tuner didn't work for me as my TV didn't get any antenna signal.
I could hook up the antenna coaxial directly to my tv, but I'm concerned as to how I can get the audio back to the receiver via my ethernet cable. I believe that HDMI are bi-directional, but I don't have an HDMI connection. I run my HDMI over ethernet now with converter boxes. I don't know if those are bi-directional. Would they return the audio back to my receiver? My setup is a little complicated now as I even have an HDMI splitter to another TV so my brain is just mush at this point!
Is there a box or device I can purchase that would "take the place" of my cable box? Something that I could connect the antenna coaxial to and then run an HDMI cable straight to my receiver? I would love some help! Thank you very much for any assistance!
OK, so AIUI, you have a TV and an AVR about 50 feet apart. You have an HW130STB near the AVR, and HDMI-to-Ethernet converters at the TV and at the HW130STB/AVR end.
OK, let's start with something simple: is the HDMI connection working? Temporarily connect the HW130STB to the HDMI-to-Ethernet converter and turn on the HW130STB. You should see something
on the TV: if nothing else, a gray box with the words "No Signal." You should also be able to point the remote control at the HW130STB and bring up its menu.
If you don't even get that, try pressing the HDMI button on the remote. That switches the HW130STB's HDMI output to five different resolutions, all the way from 480i (SD) to 1080p (FHD). Perhaps it's set to a resolution that's not compatible with your TV set.
If that doesn't work, temporarily move the HW130STB to your TV set. - it's small, and for this you don't even need to connect an antenna - and try an HDMI cable. If that works, there's something wrong with the HDMI-to-Ethernet converters or with the Ethernet cable.
If you do
get the signal from the HW130STB to your TV, then you can troubleshoot the antenna connection. You should be able to hook up the antenna, set the HW130STB to "Air," and do an Auto Scan from the menu. You should get at least one channel. If you don't get any, try connecting the antenna directly to the TV without moving it.
(You'll need 50' of coaxial cable to do this test, of course.) You may not have any signal where your antenna is located.
If your TV's tuner gets channels but the HW130STB gets none, the HW130STB is probably bad. It happens occasionally.
(BTW, if you need to replace it, consider the slightly more expensive HW150PVR or an iView 3500STBII instead of another HW130STB. These two have a coaxial digital audio output that will make it easier to connect your AVR.)
If you get any channels but not all the channels, then we're in familiar "optimizing your antenna" territory on this forum.
Lastly, try adding the AVR into the mix. You should be able to go from the HW130STB to the AVR with an HDMI cable and from there to the TV with the Ethernet cable and converters.
At this point you may discover that the HW130STB's digital audio output is problematic. If you get weird "echo-y" audio, it's a bug in the HW130STB firmware. You can usually stop it by changing channels and changing back. But if you find it intolerable, once again you may have to replace it with an HW150PVR or iView 3500STBII and use the coaxial digital audio vs. HDMI.
