Running Cable to Garage-Help!!

[Umclemrbig]

At one point cable worked to my garage but the tv died so I quit worrying about it.
Well for Christmas I bought a tv for the garage and now it doesn't work. I go under the house and the splitter that runs to my garage has been replaced. Also, there is a cable running into one of the out ports of the splitter that is plugged into the wall. If I disconnect it, other tvs in house go out. The other out port goes to my garage(the line that doesn't work). I have replaced the splitter, run new cable, rescanned for channels from tv and now I am stuck. Any help would be most appreciated. And for the new year, the person who helps me conquer this issue will receive a new Witte nut driver set. If u would like to text just inbox me and I'll send my number.

I assume you have the TV set to scan for channels on cable vs. over air antenna.

 

[Umclemrbig]

Yep-I tried an HD antenna and didn't like the signal for some stations. Then I tried a cable box and it never showed a signal

How long is the run to the garage?

Is this a 2 port splitter?

Have u tried swapping cables on the splitter to see if the problem travels with the port?

What brand splitter?

 

[CNGsaves]

Did you test with another TV ??

Or did you test right at splitter and avoiding the run to garage altogether ??

You haven't really determined your ROOT CAUSE yet.

 

[Umclemrbig]

The splitter is under the house so it's inaccessible that way.

Are you using a HD cable box? The new digital HD signals are really picky about needing to be clean and strong. The time when the cable use to work in the garage was that back when the signal was analog?

 

[Umclemrbig]

Yes to analog and I have tried an HD box and and ran it straight to computer

Cables and splitters are cheap . . . . I'd RE-DO everything from scratch so you know exactly what you have, where it's at, AND everything works.

As a general practice, CENTRALIZE all your RG6 cable runs to the one splitter location that is fed by incoming cable from CableCo - - - - like in unfinished portion of basement or utility room.

If you feel that problem is with the drop that CableCo has from pole to house (ie aerial) or buried underground from alley to house if you have buried service . . . . THEN . . . have CableCo put in new drop (if necessary) and have them check signal strength. Most CableCo's will also give you RG6 cable (or at low cost) to finish out room-to-room distribution of cable within house. Good CableCo tech might also give you quality splitter while he's there if a bad splitter is your problem. Good luck.

I made fresh runs from splitter and upgraded the splitter.

Maybe there's no analog signal on your cable anymore, and you need some kind of digital converter. The last analog channels disappeared from my cable about a year ago - now everything needs a digital box.

 

[Umclemrbig]

I hooked up a digital box-no dice

Sounds like operator error to me. Did you do your own terminations on the cable? You may just have a poor connection.

 

[Umclemrbig]

U redid the connections twice and pulled like hell and they aren't coming loose

As suggested you may need to crawl under the house and switch ports and see if the house tv's still work. I've bought new splitter that was bad out of the box. What Mhz range splitter did you buy?

 

[CNGsaves]

Keep It Simple . . . remove splitter and cable run from testing.

Go from one working TV (direct off incoming cable from CableCo). Test with another TV. Then add splitter, and rinse and repeat.

You still are no where close to ROOT CAUSE.

Are you using proper RG6 cable and COMPRESSION connectors and compression tool ??

can you post a picture of the splitter? with one of the feeds cutting the rest of the house off, you are either at the very beginning of the distribution in the house, or it sounds like you may beworking with a backfeed amp and that is the power feed you are disconnecting.

Also, please clarify, you have replaced the splitter, i understand that, did i also read that you have already re-ran the wire? if that is the case try to trace and map your cable system thru the crawl starting from the D-Mark on the side of the house.

Do most/all the other cables run to the D-Mark?

 

[Umclemrbig]

I posted a pic of the splitter above. Here is what
Is plugged into one of the out ports.

When I disconnect this from the splitter at least one other tv goes
Out.

you are tapped into a power feeding run, ****** cable guy did not remove the splitter. Somewhere in your house (maybe behind tv, or at the D-Mark) there is an amp, you need to remove the splitter and barrel it*, and extend/pull back the garage feed to where that amp is. you are splitting power, hopefully no damage has been done to your new tv

Edit: *Barrel the power that is.

 

[Umclemrbig]

So if I take out the splitter and have a straight run from power to Dmark and then split on a different cable (like to tv in living room) I should be ok?

[pattenp]

That is a power adapter for a signal amplifier. It shouldn't plug into a splitter. Where is the amplifier?
I am a little late, typing on my phone.

 

[Umclemrbig]

I think he added a second box and stuck it in there. The cable runs to it

Start from OUTSIDE the house at the D-Mark. Connect fresh good RG6 cable from there and lay it temporarily on ground and into house where you'll test one or multiple TV's with the new splitter you are trying.

Sure sounds like you have no idea where cables are going. You shouldn't be needing an amplifier with just 2 splits of TV signal (ie only 2 TV's total).

What length are longest runs of RG6 cable ??? From where to where ???

Do you also have INTERNET service from CableCo ??? Have you traced that cable so you know EXACTLY where it goes ???

 

[Umclemrbig]

I have one cable modem and three tvs up stairs. There is one cable running up there with amp and a two splitters.

Downstairs I have cable drops in 5 rooms and the line I'm trying to run.

You're battling a . . . . "Frankenstein" . . . setup !!!

So to RECAP . . . . you're trying to run 4 live TV's plus the Internet feed on RG6 ??

You are prime candidate to rewire all that with home runs down to unfinished space so you could just have one HIGH QUALITY 4 or 6 way splitter.

You'll want to get very astute at fish taping down through wall cavities and NOT doing jerry-rig workaround of drilling through walls and routing cables on exterior of house. Those are the standard jack-wad work of CableCo techs that you do NOT want to allow (ie walk around house with giant long drill) !! Instead, plan out locations on interior walls if you need to totally abandon prior locations of haphazard cable runs.

Every house SHOULD have each room's RG6 CATV cabling all ran home run to common centralized location. That is only way you can properly manage splitters and implement amplifiers if needed. Also, it's so easy to change the rooms which have live feeds.

 

[Umclemrbig]

The house was wired when new. My buddys a contractor and built it for himself so I'm sure he had it done right. But who knows. Upstairs is a home run with a four way splitter. That I know because I put in the home theater. Downstairs who knows. It was my first foray there.

If I remember correctly he used RG-9

Those are good connectors. Theyre SNS/snap n seal brand. Comcast uses those.

I usually use those(but with a different tool) and never have an issue.

Good job using compression connectors instead of crappy crimp on connectors.

It should be RG6...

How long is the run to the garage?

U need to tap in at the demarc...

can u draw in paint the wireing from the Pedestol to the garage.

i used to be a cable tv contractor so i did this alot.

there are 3 possibilities, too much signal, too little signal, or improper wiring/connection broken
