I don't think my HD is working, any suggestions?
Posted on 1/20/15 at 9:27 am
Posted on 1/20/15 at 9:27 am
I'm not at home now so any advice will be put into action this evening when I get home. A little background- just moved to a new place and bought a new TV as well. The TV is brand new out of the box so surely it's not a problem there. Comcast (yes, I know, first mistake. they suck) came and installed everything last week. However, it doesn't look like the HD is coming in like it should. I'm on the HD channel but is just looks kinda...off. Sort of like halfway between standard def and what HD should look like. I'm using a new HDMI cable as well so that's not it. I also called comcast and they said everything is all good from their end. Any suggestions?
I am not technically inclined AT ALL, so this is probably a stupid question. But the only thing I would even hazard a guess on is that the cable line is split as it comes out of the wall, would that matter at all? So basically, the coax line is coming out of the wall and then into a splitter. From the splitter, one line runs into the modem/router that they gave me. The other line from the splitter runs into the back of the TV. The HDMI cable runs from the cable box to the TV. Again I have no clue if that matters, just trying to come up with any info that might be useful to the board.

Check the video output settings on your cable box
* also, the cable wire should be going to your cable box and not the back of your tv

so there should be no coax cable whatsoever going to TV? I should only have the HDMI cable going from box to TV?
I swear, and I texted my buddy while it was happening, the comcast guy was high as balls. It wouldn't surprise me in the least bit if he fricked up.

Do you have another HD tv to compare? It could just be an issue of panel settings (a lot of TVs don't have the best settings out of the box).
Splitters by themselves inherently weaken the signal, but should not affect quality. If it does, there's a signal problem occurring before the splitter that's just being exacerbated by the splitter. Comcast should be able to test this. Whether they give a shite is a different issue. The coax is going to your receiver, not the tv, right?
The other possibility may be your expectations of HD broadcast (720P), and/or TV size and viewing distance. If you bought a 60" TV and are sitting 6 feet from it, 720P won't look so good. But I assume you were watching 720P broadcast at your previous residence.

One coax is going to the modem, the other coax is going directly to the TV.

Previous residence was a roommate's TV so I have no idea what the settings were. It was a 60" panasonic and the HD looked like a normal HD should. I bought a 60" Vizio and sit the same distance away. HD looks bad. I guess I can play around with the TV settings, but I don't really know what optimum would be. I'll try just experimenting with them.

Don't worry about TV settings for now. This is your problem. Your cable box isn't receiving any signal at all. Comcast guy is dumb.

I knew that fricker did something wrong. Oh, I forgot to mention the window he was supposed to be there was 10am and noon, and he got there right at about 2pm. Dude was in lala land.
I will go home for lunch today and update and report back.

so you have not been using the cable box to control the tv? Are you changing the channels on the box or the TV? That is weird.
Also, they should not have set it up with a splitter to your modem and TV. It should be individual cables going to each... If so, this was the laziest installer ever. You should get on comcast about that shite and have them send a non-stoner to correct the first guys mistakes.

There is nothing wrong with using a splitter. The only considerations are signal level and quality, and usually there is enough to go around. The most common precaution is to give the modem the -3.5 dBmV leg of a 3-way splitter, which is what I do in my attic for the main media room.
If there isn't enough signal, it's often possible to add a quality amp like the Motorola Signal Booster. I use one in my media room for the leg of the 2-way splitter that feeds my cable modem and HD HomeRun Prime via yet another splitter, and there's still another splitter between Prime and tuning adapter. The other leg of the main 2-way goes into the telephony modem and is unamplified so it will work during a power outage even after my UPS has shut off. Signal is nominal at all devices, and they all work great. So there's an example of an amp being added after two splits (one in attic and room) and still performing fine.

But when the service provider is installing service, they should do it the proper way so you can split to your liking later on. It is obvious that the tech was just lazy.

The tech was definitely dumb and/or lazy for connecting the coax to the TV. As for the splitting, it depends on how it's split. Regardless, if you have both cable and internet, the coax is gonna be split somewhere, probably in the attic. It would be lazy if the tech did a second split in the room with a TV and the modem, but I've seen it done that way too. Not 100% sure this was the case though.

Ok I misspoke a little earlier. This was installed Friday afternoon and I've been out of town from Saturday mornign til last night so I wasn't 100% accurate, my apologies!
So the setup is this. There is a cable coming out of the wall into a splitter. The coax on one end of the splitter goes into the modem, and that is the only thing going into the modem:
The 2nd coax coming out of the other end of the splitter goes into the cable box into the "in from box" area, a separate coax cable runs from the cable box "out to tv" area and into the TV, in the "in from box" area. There is also an HDMI cable going from the box to the TV.
The way the dude had me setup I was on some weird input which I realized why I wasn't getting HD. So I ended up moving a cable to a different spot and changing inputs and I did get HD, so that's a positive! However, it was awful reception. It was like it was hiccupping...it would flash to black in and out every couple seconds. I never got a solid picture/sound for more than a few seconds. So I called comcast and they said everything was fine on their end and didn't see any problems.
I'm sure there's probably some super easy fix I just don't know what it would be.

I think that's far from standard practice, and the only reason they'd ever run a second line is if they couldn't get acceptable signal any other way. That said, if the signal is so marginal after the main splitter that it can't be split in half at least once at each outlet, that's probably a future service call. That was not the case for me. I needed an amp in my media room due to all the equipment, plus the Prime has a hidden three way splitter inside it for its three tuners. Running a second line wouldn't have helped me, unless it was a separate full strength drop.

Running coax cable from box to TV was an odd thing to do in this day and age when you have HDMI (or component or even composite). You can remove it.

When I unplug the coax from teh back of the TV it instantly loses picture. Shoudl I also undo the other end of the coax at the box? So basically that would leave me with coax going from the splitter to the box, then only an HDMI cable from box to TV.

Yes, do that, and you'll obviously need to be using the TV's HDMI input.

Cool, will try when I get back home. Thanks for the suggestions, I know this couldnt' be more basic but I just don't really know what I'm doing.
Posted on 1/20/15 at 4:13 pm to WG_Dawg
I did that and it's not helping. I can see the HD now, but it's just constantly blinking/flashing to where it doesn't even play sound
Posted on 1/20/15 at 4:15 pm to WG_Dawg
And it's not doing this with Netflix, so I'll take that to assume the problem is with Comcast?

The way you are describing things is quite confusing...
