xbox 360 - wavy purple lines

My old release 360 finally gave up the ghost as far as I know, when I power it on, we just get wavy purple lines. Am I correct in thinking its the video card? If so anyone have to replace one and how much did Microsoft charge? I already bought a shiny new elite to replace it(got a free $50 gc with it from wallmart), but was wondering if it was worth saving it to bring to my folks or inlaws for when I visit.

The 360 doesn't have a video "card", per se. The GPU is part of the mainboard, not on a card that can be swapped out. (You are probably correct in your assessment of the situation, though - GPU failure is a good bet. My launch 360 behaved very similar right before complete failure).

Out-of-warranty 360 repair from Microsoft is $120 plus tax/shipping, if I am reading their page correctly.

That sounds more like a video input or cable issue. If you are using a RGB Component cable, if the green input/line is defective, or you accidentally plug it in wrong, your picture will have a strange Indigo filter appearance to it.

Have you tried it on another TV, with another cable?

Had something similar happen to my second Xbox death, purple crash screens/fragmented images. GPU died had to send it in for repair..

My 360 burped a bunch of purple boxes and lines onto the screen the day it red ringed.

used the same standard cable from the old xbox on the new xbox, and don't get the purple lines, so most likely is the GPU then. So good thing I just replaced it, now I need to find a memory card so I can transfer game saves.

No need, just slide the hard drive into the new or repaired unit. I would pick up an Arcade for $199, as the new chips have really eliminated the bulk of the red rings and such. Either way, you take your hard drive out before sending it in to be repaired.
