On My 3rd 2400MP... About to give up!

Question

My first 2400MP worked great for about 2 weeks, then DVD input via (S-Video -> S-Video) and by (Component -> VGA Breakout) cable became distorted and unwatchable (flicker and signal loss).  I tried multiple DVD players and had the same results.  All other sources continued to work fine (480P, 720P, 1080i HDTV, Xbox 360, VHS, LD, etc.).  Dell exchanged the item with a brand new one.   My second 2400MP worled great for about 1 month, then a horrizontal line showed up which scrolls from bottom to top with all sources (DVD, progressive & interlace HDTV, 800x600 VGA, 1024 x 768 SVGA, VHS, Xbox 360, etc.  Dell replaced the item with a used / refurbished one.   My third 2400MP (used / refurbished) had the exact same symptom as #2, scrolling horrizontal line on all sources.    I've tried replacement cables, factory reset, multiple laptops, DVD players, and HDTV tuners... no luck!  My other Dell projector (1100MP) does not have any of the above symptoms when used with the exact same equipment.  Has anyone had a similar experience or have any suggestions?   Thanks.

our company recently purchased one and we've had it about 3 weeks. I am about to call my rep to get the next model up or replace it. We have it connected to a Optiplex SX270 for use with VNC to a Linux server. the xterms are horrible. Some of the text is darkened and when you move the window the darkened area stays in the same spot, almost like shadows on them mirrors.

how do you hook up the xbox 360 to the projector? do you use that standard avi jacks or the hd jacks?

The problem is resolved... no thanks to Dell.  The first projector that had signal loss really was defective.  The replacement projectors were all scrolling a faint horrizontal line up the screen as a result of a ground-loop issue.  Everything was connected properly, however it required a visit from my cable provider to solve the ground loop issue between my brand new house and the cable junction box.     A good test for anyone with a similar problem is to watch a DVD (with the component -> VGA breakout cable) to the projector... when you see scrolling lines, disconnect the coax cable connection from the wall receptacle (even though it has nothing to do with the DVD you're watching) and the lines will magically disappear.  Why this wasn't even considered by Dell technical support is beyond me, and cost them a substantial amount of time & money.
