Does anyone have any idea what the problem is? Could it have something to do with the TV itself, or is it an electrical problem?
I have slight moving gray noticeable only if the brightness is very high and the screen is all black or mostly dark. It seems to me like its interference too. I did not even notice it at all until I hooked up the Wii with component cables. I don't see it at all with my other inputs so I suspected the Wii or the Wii component cable which was not the Nintendo brand cable but an import.
Since then, I also noticed it with the PS2 but only very slightly. I unplugged everything from my system and I have the PS2 going through the TV but its a digital connection so I doubt that is related.
For me, its almost not noticeable and I also suspect it could be related to something someone else is running on that power line in my building. I have considered a power conditioner but the problem is so slight I figured it may not be worth it and it may not even be the problem.
The strange thing is, I notice it most with the Wii and the component hookup. With the composite hookup I don't think I ever saw it. Also, I don't think I have ever seen it on the TV input or the 360 at all. They all look very solid.
Very strange indeed.
Also, keep in mind a "Surge Protector" is not a line conditioner and even some line conditioners don't eliminate noise. I get the feeling its not the power but I am no expert.I am defiantly going to try removing the Sound inputs from the Wii and see if that has an effect on the interference.
I will let you know if I find any relationship between the two. I admit the Wii is the only device I have going through analog on the TV so I guess its possible.Also, if you get that 99$ video isolation transformer thing, let us know if it worked. 99$ is not drop in the hat but if it works it might be worth it.
After reading up on ground loop noise, I don't think that can be my issue because I have all my equipment hooked up to the same/single outlet.
Video hum may be a problem in any system where video sources and display devices are connected to different A/C power sources with varying grounding potentials.
So I don't see how that statement could apply to my situation.
UPDATE: I just went to see if disconnecting the sound would make a difference but before I could test anything, I did not see any banding/interference. So for me it seems like its not always happening so I think its related to things not under my control. If I see it again, I will try it though.
