I have a 3790 and I've noticed something very strange about the svideo output. Everything outputs fine when the system is running off the battery, however when I plug the laptop into the AC adapter, I notice that a faint, skinny, horizontal, black bar that slowly makes its way up the tv screen until it reaches the top, then it starts again from the bottom. I could understand (sort of) if it were happening all the time, but that horizontal bar doesn't appear if I unplug the AC adapter and let the laptop run off the battery.

Anyone else experience something like this or know of any possible ways to fix it? I'm guessing that its probably poor design and the power from the AC adapter ends up interefering with the signal or something, in which case I'm out of luck...

Thanks
