View Full Version : Component cabling issue

Any help will be greatly appreciated.

I recently decided to tear out my fireplace and built in entertainment center and opt for a more modern look in my house. Due to the remodeling, the wall which originally housed the fireplace and entertainment center was without sheetrock. I decided to wire the wall for any and all connections I might currently need and would need in the future.

I have 2 locations on the wall for component connections, each with a component hookup running directly to behind my tv and to my a/v receiver. I used 15ft component cables for the in-wall installation and terminated each cable using modular keystone jacks. My hope was that I would simply be able to plug in my Wii, or Xbox 360 to one of the connections and use a 3ft component cable to connect the other end to the a/v receiver. Not a single component connection in my wall is currently working and the sheetrock has already been put up. Does anyone know what I did wrong?

I have the wall plates off so I can see the cables plugged into the jacks and the connections are fine, and I've tried every possible combination to ensure I didn't cross any wires somewhere. I figure for each connection there is maybe a total of 22ft of component cables being used, will it maybe not travel that distance?

I apologize if I've been unclear, I've been battling this issue for hours now and have no possible explanation of what could be wrong. I'll be happy to further explain something or go into greater detail if needed. I'd really just hate to think that I put all of these connections in my wall for nothing.

Make sure component cables are plugged into the a/v receiver input and not output.

Not to echo the exact sentiment already posted, but do check the very most basic things first. We've all been there...things just aren't working and you start to suspect this and that when instead, its pilot error. ;)

I'd think the chances of the cable itself being bad or having been damaged in installation to be pretty low. I would take a look at the wall plates/jacks, though.

If the wire in the wall is terminated for component on each end, why not try it without the wall plates in the path and start to eliminate variables? I'd also try just analog audio over the cable if video doesn't come through.

It will definitely go way more than 22 feet. I agree, taking the plates off should help quite a bit in tracking this down.

To trace the wires, you can take an old RCA terminated cable and cut off one end, leaving a littel wire. Then you can strip and twist the wires together. Plug that into one of the jacks and you can use a meter or continuity tester on the jacks on the other end to make sure which jack is which.

I also like the suggestion of just running audio on each cable. Hook a source up to one end (just use right or left, it does not matter) and have your receiver on the other. you should be able to turn it on and then plug the cable into each individual jack and when you hear sound you know it works and which cable it is.

Well I was able to get one of the connections to work. I have 4 component hookups on my wall. 2 run directly to the tv and 2 run directly behind the a/v receiver. For 3 of the in-wall runs I used 15 ft component cables from monoprice and one of the runs to the a/v receiver I made with a shorter component cable I had from a previous cable box.

So far the one made with the non-monoprice component cable is the only connection I've been able to get working. The only way I accomplished that was to switch the 3 ft component cable I had going from the wall to the a/v receiver (which also came from monoprice) to another component cable I was using for my satellite box.

Currently I have one of the 15ft monoprice component cables, from the same order that I received the others in, hooked up in my bedroom and it's working fine. However it runs directly from the tv to the satellite box.

I looked for a tone generator at Lowes today but they were sold out, so I will have to call a friend to get his and test for continuity. However (and I don't know if this would be considered a viable test) I have the other connection behind the a/v receiver currently hooked up (patch cable run from the wall connection to the a/v receiver). I'm not able to get a signal across it, but when I hook up my xbox 360 to the jacks on the other end I'm getting feedback on my surround sound system when I initially plug the audio cables in. So it's as if there is definitely something being passed across the cables, but that's all I can get. No actual sound is actually being passed through.

If I can't figure this out soon, I'm thinking I may look for some of the F connector to RCA jacks and change the ends of the cables in the wall.

I've just got so many cables in my wall now that it would break my heart for all of these component connections to not work.

You don't need a tone generator to test for continuity. Do you have a regular Volt Ohm Meter (VOM)? That works just fine.

Monoprice cables are usually pretty good. I would find it VERY hard to believe that 3 of the 4 cables are bad (and all 3 wires at that).

Do the wires in the wall pass through any studs? Any chance the wires had drywall screws put through them? I would unplug all the cables at both ends and test for continuity. If there is any continuity I would expect a screw has been run through them.

From there, take each cable and test for continuity using a cut RCA as mentioned before.

Just curious...did you test the cables BEFORE the drywall went up?

On a tip from BigmouthInDC I tested all mine (from monoprice as well) first. Now that the drywall is up, we're hosting a Halloween party in the barely finished basement I hooked up a HTib and fortunately all the speaker cables still work. I haven 't hooked up any HDMI sources yet to test those out.

Good luck!
