It has specific audio inputs for just such a scenario. The question now is does the composite input have it's own dedicated audio inputs also. Manual isn't clear and there's no pic of the entire back inputs. In fact pics in manual might not even mimic what tv actually looks like. Don't come back to me if it isn't so, but I've never seen a TV with composite video input that didn't have an accompanying pair of audio inputs next to it. Usually all on "phono" (AKA "RCA") connectors, which has always seemed an odd choice to me for a video signal, as surely it was originally intended to be an audio connector (though I've even seen it for UHF, e. g. modulator outputs). Actually it should read "RCA (AKA "phono") connector." I think it became known as a phono connector because people weren't really sure what an RCA connector was, so to clarify it for the average user, it was referred to as "phono." I can remember (barely) way back when I started getting into hi-fi stereo equipment, my more knowledgeable friends would talk about RCA connectors, and I really didn't know what they meant until I was shown one, and I said, "Oh, a phono connector" :-) But I digress . . . :-) The Cinch connector can be used two ways. You can solder a twisted pair to it, one conductor ground, one conductor having an audio signal. And that makes it a kind of audio cable. But you can also solder a coax cable to it, the braid goes to shield, the center wire goes into the pin. That provides a roughly 75 ohm environment for controlled impedance transmission of high frequency baseband or some kind of RF signal. As a result, you may see different kinds of cables with Cinch on the ends, and they're not all created equal. You have to think about what you're doing, as to whether a "thinner one" is the right one for the job. http://www.avsforum.com/forum/91-aud...deo-cable.html If you make up a twisted pair of wires, the transmission line impedance may be around 100 to 110 ohms or so. This is why you can still *attempt* to run video through such cables, but it isn't a good match for the impedances on the ends of the line. There might be reflections or ghosting seen. And there's a whole corpus of info about running audio signals that I won't attempt to rewrite - because I'll get it wrong. The above is just to give some explanation of how there can be two types of cables. Some of the Cinch audio cables were invented before there were video applications, so there was no need to be using coax for everything. I've worked with Cinch as a hobbyist, tried to solder to it, and so on :-) What a mess. If you get the central pin too hot, the plastic dielectric can melt. The pin can end up off-center. There's no guarantee that the materials used inside a Cinch, are "soldering iron safe". To connect to the shield on the Cinch, some have a curved lip, and you can wrap solid wire into that lip, and twist the ends tight to get a grip on the connector. That might work to allow jerry-rigging a cable you made. I have also tried soldering braid, or wrapping solid wire around the braid where it meets the shell. But it's really a mess to be making your own cabling. There are other coaxial connectors, which come as an "assembly kit", you strip the insulation, and a ring nut clamps down on the materials and makes a nice connection. I've not seen anything similar for Cinch, so it's "solder and pray" as it were. Paul |

Having never heard of a Cinch connector, I turned to Google and found that Cinch is a company that makes well over 200,000 kinds of connectors, which begs the question, when you refer to a Cinch connector, are you referring to an RCA connector? When I check Google images for a Cinch connector, I do get images of RCA connectors, (among others), so I think that's it. Is Cinch a popular brand name in your neck of the woods? Is this very popular connector not called an RCA connector up north? With so many companies making them, I'm curious to know how Cinch got themselves associated with this item. I get the idea regarding Kleenex, Velcro, and Jell-O, but Cinch is a new one. -- Char Jackson |

Though can't understand why "phono" is more intuitive (I wouldn't have thought of phonographs). I used to think of them as "why use four when one [DIN] can serve the purpose - far more opportunity for plugging them into the wrong place". (But see below re DIN.) But I digress . . . :-) I like digressions too (-: The Cinch connector can be used two ways. (Like Char Jackson, I had no idea what you meant, but like him I'm assuming you mean what the rest of us are calling phono or RCA.) [] I've worked with Cinch as a hobbyist, tried to solder to it, and so on :-) What a mess. If you get the central pin too hot, the plastic dielectric can melt. The pin can end up off-center. There's no guarantee that the materials used inside a Cinch, are "soldering iron safe". Same applies (with knobs on because you're trying to make about five connections) to "DIN" connectors. [Yes, I know DIN - Deutsche Industrie Norme - is a standards body and covers lots; I mean the about half-inch ones with lots of, usually but not always audio, pins, at one time beloved by Philips, and many German manufacturers (Philips Gloeilampen was originally NL).] My original cassette recorder - the one with the "gearshift" control, rather than piano keys - had them. I used to like the _principle_ of the (180°) DIN connector: much more compact than four phonos, and you couldn't plug the signals into the wrong place. (I also much preferred them horizontal, rather than rotated 45° into a sort of "diagonal" alignment as some chassis did; no technical reason, I just thought they looked neater.) However, it did suffer from corrosion of the pins (did they use bare aluminium or something?), as well as the tendency of the plastic holding plate to melt during soldering. [] -- J. P. Gilliver.

Took three days for Walmart to email confirmation item was shipped. When purchased delivery date instead of the 19th became the 22nd. Had a Loomis Waybill/tracking # with the email. Looms seems to know nothing about the Waybill # even 48 hours later. Looms calls me back stating Walmart has issued the Waybill # but not yet used it. I'm wondering WTF is going on then? Walmart calls next day after an email prior day asking questions. I'm told sorry that Waybill # is not valid but call finished without me having a valid waybill #, expected delivery date or if it's even been shipped yet. I was left feeling/thinking - Well so much for that family Christmas present being under the tree. Well it came today. One day after original date web site gave when purchasing and day before email stated it would be delivered. I'll hold off being happy about it until I see tv channels, PC and Blue- Ray all properly working with a good picture and decent sound. Some couriers allow the users of their service, to issue their own tracking number. However, the number does not mean an item is "in the system". In the case of US Post/Canada Post, an item can enter their system and from there, no further tracking info is collected. Until it arrives in your letter box. Tracking systems in 2017 are highly overrated, because hardly any of them work properly. You really have no idea where an item is - it might not have left a shipping dock. Even though you do see the truck driver scanning the item, taking your signature and so on. The tracking info is still there, it's just not available to a consumer. Paul |

What I am curious about is that that same HDMI port also appears to be an HDMI output for connecting to digital recorder etc. Didn't know they even allowed that feature and always assumed any recorder would have to be before the tv saw it, e.g. copy protection.
