HDMI cable confusion encore

post #1 of 11
Thread Starter 
HI All,,,just wanted to let you all know that I finally found the problem. It was my cable box and not the 'cheap' Colby TV set. It was replaced by TWC with a Samsung SMT-H3050 brand and now I can also use my HDMI cable to the Colby and the sound is there. Just like to mention a curious situation prior to my having to replace the box. The Colby support team told me to do some changes to the component inputs. ...and to repeat it at the older cable box outputs. Remove the green cable and put it into the standard Video input and the box std Vid output....then go to Colby's input settings and choose "AV" input...remarkably, it gave me not only the video but also the audio. Isn't that weird? Nevertheless, I prefer the HDMI cable connection better. One caveat..now i have to get a reliable hdmi coupler, if I want to view HD with my main 55"" TV set.

First congratulations - that is great.

On the "weird" part - no that isn't surprising. Basically you selected a different (standard def) output so it probably changed the configuration of the (old) cable box.

Finally, why do you want a coupler? Removing and inserting an HDMI cable is not a good long term solution. It can cause failures if done over a long time.

For your setup with the Samsung cable box, I'd simply run the component video outputs to your 55" TV. I think you said the cable box and TV were close together. That way you never need to connect/disconnect a cable nor deal with HDMI switchers or splitters. Much less headaches.

Well its the only way i am able to get HD resolution from my cable box to my main 55'' TV. The box only has 1 output. The other setup was the box and my Colby which is about 15' away, and that is where i am getting my HD...on the Colby. I thought with a splitter and/or a coupler, I can insert it into the one hd outlet of the box and then attached 2 hdmi cables, one going to my main TV and the other to the kitchen one. I guess if it works then i wouldn't need to unplug and replug. The other thing about the Colby manual says nothing about that "AV" input, its just there. Don't know what its purpose other than when I clicked on it, it gave me my sound., before I changed the box. Now, I use my component connection from the box to my main TV....

Your new box has 2 HD outputs (component and HDMI), looking at the owners manual. So you can use both of those (assuming they are both active simultaneously).

A coupler simply attaches two cables to each other, making the combined cable longer. It does not add any connections.

What you would want is a distribution amp, more commonly known as a splitter. That would take one input and provide you multiple outputs. However, with HDMI your Colby could cause a problem. It's complicated but basically HDMI can only send out one video and one audio signal at a time. So, your cable box will try to send a signal that is compatible with both the Colby and your 55" TV if you try to use a splitter. I have no idea how the Colby will change the video that is going out to the 55" TV. It could be the same if both TVs have the same capabilities or if the Colby has less capability than the 55" TV, then your 55" TV will also get the lesser signal. "Turning off" either TV will likely not change anything since the HDMI cable is still active.

Anyway, that is why I recommended using the component video output in this case.

I am finding strange things going on since I got the replaced cable box. Like I said previously, its all setup with HDMI going to my Colby and the components going to my Samsung 55''. Last night we all set to watch some TV on the Samsung 55'' and a black screen appeared with the source shown as Component. The first thing I looked for was if the power sign was on at the cable box. It was. Then I turned on the Colby to see if I could see my cable there and of course it was blank too. So I rebooted the box while both sets were on. Eventually, i saw cable on my Colby only, but Samsung still remained black with the component connection. I turned off my Colby and just as I did that, my component video finally came on. It seems one TV cancels out the other, especially if I have both on at the same time...which is very rare. In this scenario I keep thinking what good is a splitter.

That reads like good old content protection, were you trying to watch HBO or Showtime? If you want a splitter or a switch try monoprice.com. If your Colby is a 720P and the Samsung can do 1080I the set top box well output 720 with a splitter. Looks the same.

They also have any HDMI cable you need.

I think Phil is probably right although it could also be that many of the cable boxes won't do both HDMI and component simulaneously consistently. Either way, it looks like the only remaining option is an HDMI splitter. Do you know what resolution the Colby is? I'm not sure if you ever appended the Colby model number but I might be able to find out more with that number.

I am aware of Monoprice and cables and etc...the question is would they work? The Colby is an LEDTV2235 1080i,1080p. A couple of years ago I bought a 2 x 1 hdmi splitter and had the same problem i was having now...

Looking at the Coby LEDTV2235 specs, the panel is a 1920x1080 and the specs say that it can handle 720p, 1080i and 1080p inputs. So you should be OK.

What you want to make sure is that you get a 1x2 splitter (not a 2x1 - that's a switch) that has a power adapter included. You do not want to rely upon the power coming through the HDMI cable to power the splitter. Instead get an AC adapter (wall wart).

Monoprice has these as do may other places. These switches depend upon firmware (software burned into hardware) and as such are only as good as the firmware. So, you'll want to read reviews to see if there have been any problems. This is an example of switch that should work:
http://www.monoprice.com/products/product.asp?c_id=101&cp_id=10113&cs_id=1011306&p_id=8154&seq=1&format=2

This is an example of one that does *not* include the AC adapter (but you can add one). This is the type to avoid unless you add the AC adapter.
http://www.monoprice.com/products/product.asp?c_id=101&cp_id=10113&cs_id=1011306&p_id=8204&seq=1&format=2

I use Monoprice only as an example. There are other places you can find a powered splitter.

Thanks, I will look into those links. As of last night, with both TV's off, we started to watch some TV from our main TV and of course, like the previous night, I was only greeted with the Component source and black screen. I walked over to the Colby and unplugged the hdmi cable and as soon as i did that, the picture appeared on the Samsung. They recommend that I use AWG 22 or 24...hdmi cables with either of those products. I looked at my 15' cable which does work, but its covered with a light blue covering and no identification is on it, except the name of the company, I think ..."Insten" gold plated. The other two hdmi cables I have only one has a AWG number which is 34...the other just says AWG without any number.

It just needs to be High Speed for the 15' cable. At 6' most cables will work. You'll know if they don't work - it won't be subtle as you suspected earlier.

I wouldn't worry about the cables until you try them.
