Hello,I usually spend time in another forum on the asylum, but could use some help from you video inmates on my home theater setup...
I just moved my entire sound system (including HT) to a small room which also houses our new computer system, including wireless networking.
The hifi portion seems unaffected, but the Sony TV/monitor now has video hash running diagonally across the screen.
My HT system is powered through a Tripplite Powerline conditioner/spike filter. The video is routed from the different sources (VHS deck and DVD player) throught my Harman Kardon Signature 2.0 (tuner/processor) with typical interconnects and from the Signature with a higher quality run of interconnect to the monitor. Since I have no broadcast TV signal in my house, I don't even use the tuner in the Sony.
Would it be more likely that the computer is getting into the line cord or the interconnects? Since the Signature is itself computerized, I figure that it would be shielded (and the construction is sooo stout that it would appear to be!
I am ready to tackle it, but would appreciate some aiming before I ask my friend for some of the MuMetal that I think will sheild just about anything.
Thanks for your comments.
Phil
Follow Ups:
I found that the only time there is noise in the video is when the HK Signature is displaying its menu! I can surely live with that...I found that the DVD and VHS signals were clear and clean. Only the blue screen of the HK menu shows any noise.
I am happy with that, and BTW, it was the wireless router, but I choose to no longer care about it since the other video sources are clean.
Thanks for your assistance folks! You are super...HT rules!

Yep, your line sums it up. WIRELESS computer, means you now have a bunch of radio transmitters flooding your room with RFI. And what does a TV pick up? That's right, RF! That is most likely the source of your problem.Unfortunately, I don't know how to help with the problem, short of moving things or getting rid of the wireless network. Sorry.
Maybe someone else has ideas?
A good test would be for him to leave everything as is but turn off the wireless capability. Does the interference go away? If not, I suspect he may have a ground loop problem but it's not clear to me how all of his equipment is interconnected.
I have all of my equipment in a roll-around (tall) cabinet with the Sony on top. All of the power comes through a line conditioner. When the gear was in the living room there was no noise in the video. I simply disconnected the power from the conditioner, disconnected the speakers, and rolled the cabinet into the back room.Now, there is noise. So, I will put the wireless down, and see what happens to the video. If that fails, I will put the entire computer system down and check. I suppose it matters which (or both) are causing the interference.
But this brings me back to my original question of what is the most likely place for the RF to be intering my video system, the input or the power source? I won't be able to give up either the computer or the wireless system (I am working on it at the moment!).
Well, thanks for the replies, now I just have to tell the wife to get off the computer (along with me) so that I can test it. This ought to be fun! Maybe I will wait for her to finish her school work, what do you think?

I'm not married so I wouldn't be the right person to ask about how to handle your wife's need to get her school work done. ;-) But somehow I think you're on the right track. When the system is completely free and you can tear it apart as necessary, that would be a good time to start experimenting.I really don't know where the most likely entry point would be for the RFI but you first need to determine if it is in fact RFI from the wireless to begin with. Is the wireless router also in the tall 'roll-around'? If it appears to be the source of your problem, you might try moving the router further away if possible.
Thanks for the reply...no, the wireless router is across the room. Nothing on the equipment cab has changed... so I know it's in the room. It's either hash from the computer itself, the monitor, or the router; none of which I can do without ;2)
Probably I will have to shield the computer. Somehow, I don't think the router puts out enough spurious radiation to cause the video noise. But, I'd bet the computer does.
When the wife is done for the night, I will get in there for a few minutes and check it out. Then it will be time to shield.
Thanks,
Phil
