If anyone is plagued with upward scrolling horizontal lines that are driving them crazy, here's a great little product that really works!

I've had these damn lines on channels 3 & 6, and tried everything to get rid of them. Was told it was a 'ground loop. I have a MonsterPower cleaner, had the cable company out a couple of times, plus had them ground the cable (at some point my water line was changed to PVC, so the ground was lost). Had an electrician out to ground the entire house electrical system. The only thing I didn't do was a dedicated circuit. Heard about the 'MAGIC box' from Klipsch http://store.klipsch.com/details.asp?ProdID=9 , so I ordered one. Voila! The lines disappeared 95% of the time, and the other 5% they are so faint that you really have to look for them. If you've tried everything else for scrolling lines, try this - it works!

If this is about the thead I think it is then we had your problem nailed - a difference in ground potential induced by the cable ground. This "box" is nothing more than an isolation transformer circuit. Glad to hear you got it resolved!

"If this is about the thead I think it is..."

It is. Thanks.

By the way, my new family room/'home theater' is under construction, and today the electrician installed a dedicated line for my A/V components. Yeah!

I have had this problem for a while, it is VERY faint, but still there. I would love to had a component switch but every time I have done this problem get WAY worse.

Are you running a switch by any chance? If so, did this help.

Any help would be great. I would buy the device and get a switch if this would solve my problem.

I use S-Video to view the standard definition channels that were affected. No, there's no switch - it's an in-line device.

Bill,

Which Monster power supply do you have? Also, did you try splitting the cable before it gets to your cable STB and running coax directly to the TV?

BTW, how big is the MAGIC device and in the picture what is the sticking out of it on the right side?

I have the MonsterPower HTS 5100. No, I didn't try bypassing the cable box. I did however try both running it through the MonsterPower as well as bypassing the MonsterPower. The thing sticking out you mentioned is for an optional ground (not required). Try it - if it doesn't work, send it back. It works great for me - solved my problem --- nothing else I tried did!

It's about the size of a pack of cigarettes.

Bill T,

It would have been nice if he had used shielded power cable or at least the type with metal armor. That would/could have provided some end-to-end RFI protection so these silly, hi-$ shielded equipment power cables might actually do something : - )

Now you tell me!

Shielded power cable is able to conduct high frequencies the way coax does, while unshielded wire would radiate this energy off as a radio wave. UHF noise is 90% gone from an unshielded straight wire after 10 ft and 99% gone after 20 ft, and thus would not likely make it to your STB.

There are many good arguments to this debate. Without a doubt shielded power cables will reduce interference in some cases. It is not obvious to me how often shielded conduit is better than it is worse. I am presently unconcerned by the wiring in my house, which is unshielded.
