I forget - I think it is an Audio Authority DA. Either way, the problem is solved...
Ed - If you lived in the area, I would say come in and buy one over the counter... I have no idea where you can buy just one over the internet, but a good boutique retailer/CI firm in your area should have one for btw. 15-25 bucks...
Good luck

Well this is the differance between programmers and installers...
I walk into the install after the guys are all done. They say here you go. I look at teh screen and see this annoying walking line. Well since I came from install I start unplugging things one by one. See changes in the loop. Start messing with grounding... blah blah blah. INstaller comes back about an hour later and sees me digging in my bag looking for various ground breaks...
"What are you doing?"
Don't you see this loop?
"Check this out.."
Takes off all the stuff that I have put in there that lessened the loop.
Takes out a pair of dikes and cuts the ground of an extention cord. Flips it over and plugs it back into the surge strip. I complain bitterly... but the ground loop is banished! Don't get me started about my complaining about that one.. everything was on this strip and an extention cord was run from it to the projector. Sure enough.. cut the ground off and FLIP over the the prongs and it was "fixed". I need to look into what waranty just got voided.
Untill he came in, I was doing everything listed in this thread as it is S.O.P. But I was S.O.L.

Tried the extention cord thing, works great, so I need to get sparky over there to swap one leg to the other.

Hi everyone,
I have almost the identical problem with the slow,
upwardly scrolling purple and green bars. I'm
using a Sony plasma connected over component to
a Sony amp that has two component inputs for DVD
and HDTV.
As suggested above I tried disconnecting the cable
feed and that solved the issue. However I obviously
would like to have cable TV in the bedroom and
was hoping that someone could tell me how to fix
this.
I tried, again as suggested above, to pass the
cable feed through a surge protector; but to no
avail. Now it was a "cheap" surge protector ($40ish),
and after reading around a little more was wondering
if using a Monster Powerbar, retailing around
$200. I have read from numerous people that the
Powerbar solved this problem for them. Will this
do the trick for me, or am I wasting my time?
And can I save some bucks and find a better/cheaper
solution?
I see THXrick suggests a DC Groundbreak. I don't
know what that is, or whether it would help in
my situation. If it is what I need, who makes
them and where could I get one from? And finally,
will a DC Groundbreak work with my HDTV Cable
Box and a modulated CCTV channel that I soon plan
to add.
Thanks for any help in advance, it is greatly
appreciated.
Ed. Xantech makes a nice groundbreaker. It will work with your HDTV cable box and a modulated CCTV channel.

Thanks for the advice Michael,
I have ordered the Xantech 63400 Ground Breaker from hometech.com, $7.45.
I'll post my results when it arrives.
Thanks again for the help.
Ed.

Hmm, had one yesterday where everything is plugged into the same place and there's a hum in the audio. Disconnect anything to the subwoofer amp (use ground isolator, unplug amp, unplug audio cables to the amp) and it goes away. No cable TV to the house; using Dish; disconnected all lines from dish and no change...Ideas?
Also, system used an Adcom amp for center rear speaker and on the back of it there was a ground lift switch. How do you like that? Do I break the law by flipping it (I saw the ground break police patrolling just yesterday in the area...)??

There is no truth anymore. Only assertions. The internet world has no interest in truth, only vindication for preconceived assumptions. |

Well, I ran into sparky yesterday, nice guy. thought it might work, so he switched it from 1 phase to the other, didn't fix the problem...
Any other thoughts???

Hi Everyone,
Thanks for all the help. The Ground Breaker did the trick. The picture is now completely clear of the scrolling lines.
One thing I did wonder, and I'm fairly sure it's just my imagination, but does the ground breaker decrease the image quality at all? I thought the image appeared a little, and I mean only very fractionally, fuzzier, or softer.
Again I think it is somewhat my imagination and perhaps my disbelief that an $8 part completely resolved my issue.
Also, just for my own interest I would love to know how the ground breaker works. I'm just fascinated at the fact that this tiny piece of plastic has made my day.
Thanks once again for all your help.
Ed.
