Interference With Component Cables
Posted 24 March 2010 - 06:16 AM
and away I went. (After turning on 1080, 720 & 480p modes through Enigmah Video switcher)
However, I am having trouble with interference that moves across the screen in vertical bars...
The strange thing is, it only happens in 720p mode, ie, using Xdescent in 720p mode & Xduke etc...
Also Final Burn Legends & Xport emus in 720 mode (haven't tried too many others yet).
If I am using 1080 mode in Final Burn Legends or Xport emus, this interference doesn't happen at all...!
I initially put it down to using 3rd party cables that weren't shielded as well as official ones,
but if that was the case, surely it would do it in 1080 mode as well....
Does anyone have any suggestions as to what might be causing this?
Trying to find official component cables now is like trying to find hens teeth. (Anyone have some?)
I also noticed when I have my network cable attached to the Xbox, that the interference becomes
a lot worse, brighter & throbbing looking as it moves across the screen.
Any help would be greatly appreciated.

They're used via an official MS HD pack component cable going into the same (CRT at 480p) TV as my XB360. I've tested my XBoxes and XB360 at both 480p and 1080i
and the XB360 shows the interference at both resolutions. There's a hint of some sort of mild interference at 1080i on the Xbox most noticeable when using the menus in XBMC but it is no way as obvious as with the XB360.
Initially I thought the independent make XB360 component cable I was using might the problem. So I bought an official MS replacement but that resulted in no improvement.
I've had similar trouble on a Philips CRT when using a RGB SCART cable with a PSOne. That was solved by either re-tuning the TV to a blank channel before switching on the console or, as I eventually did, removing the video and audio output SCART pins.
You can't do the latter with component, obviously, but the the former ie,. re-tuning to a blank channel before switching over to whatever AV input you're using, might be worth trying.
I've also had intereference trouble when connecting my amp via the AV output block provide on many types of games console cables. This was resolved by a), using a better quality, shielded, cable to go to the amp and . using a separate in line AV breakout connector instead of the the AV block,
In my case though the TV I'm now using isn't connected to anything else ie. no aeriel or cable TV it's just being used as a monitor for gaming/XBMC. I'm not online with it either so no problem for me from that quarter. My UK PAL Dreamcast suffered from some nasty inteference problems when connected online until I re-routed the connecting telephone cable away from the TV, other cables and replaced the telephone wall socket with a proper BT (British Telecom) one.
So where on earth is the interference coming from in this case? If it is a grounding issue as some others have suggested how (details please) do you go about resolving the problem?

Still have to get over my mates to try this stuff out, also gonna have a tidy up in the snakepit at the back of the yv, have noticed a red green moving tint on the ps2, which was not there before also.

I found another thread here which listed possible causes of such interference and apart from the grounding matter (please, somebody, explain the problem/cure) it also mentions using a multi-input surge protector.
I do indeed use a 8 way type but only the TV, specific console I'm using and amp are powered on at any one time. Nothing else is on at all not even in standby. So if this is a possible source of the interference problem can somebody, again, explain the whys and wherefores?

if the problem is still there disconect the cable into the tuner/cablebox/tv
then plug everything back in one at a time looking for the problem to return..

ie, get back to the very basics of tv and xbox only, then work up from there till problem
surfaces... (remove Xbox & tv from area/cabinet to test if possible too)
In my case, it was the wall plug that was giving me interference, so I plugged my Xbox
into another wall socket, but also found that running my aerial cable through my
belkin surge protector created interefence too.
So I disconnected the aerial from that and plugged straight back into the tv.
Also, as mentioned, a snake pit behind your tv can cause this interference, with wires & cables
crisscrossing each other, creating "cross contamination". I had this too with the component cables
touching other cables (especially Xbox power cord).
Best bet is to tidy them up as best you can & keep them all seperate (not easy lol).
Also worth trying is checking/cleaning your connectors on your plugs & sockets,
is it loaded up with dust grime etc?
Hope some of this helps...

I will post back over the weekend after i test in a new environment.

I have eliminated two possibles causes though in this case - I plugged the console into a completely different power socket from the TV (direct ie. no surge protector) and the interference was still there. I also disconnected the red/white stereo leads from the TV too (I use TOSlink for audio) - no improvement either.
Thing is what happens if I find I get the interference with just the TV and console connected alone.? As said I've used both an official and independent Component cable so far and unless I've been unlucky and both are faulty what might be the cause then? I definitely have no similar problem on the same TV with my PS2 or GC via Component.
It's why I'm so interested in hearing more about the possible grounding issue mentioned earlier in both this thread and others as being a likely source of the interference but, as yet, nobody has explained.

Like i said my mate has a modded box, so im gonna do a mine over his his over mine test, i will let you know what happens, promise i will tell the secret lol.
Here are some shots of my problem, although it does not look that bad in the pics, trust me it is, just look for the white horizontal specs.
This is 1080p
