Since getting my console back after having it repaired, due to the red ring of death problem, I haven't played it much. I decided today to sit down and play Assassin's Creed, and about five minutes into it, my screen starts to look posterized. Basically, it looks like the colors are reduced. Think cheesy 80's music video special effects. Here's some shots:

Of course, if I go to XBox.com and look up my repair information, it says I'm out of warranty. Fantastic. A console I hardly play is broken yet again. I'm going to try to call and deal with their customer service people (in India.. ugh.) But I doubt I will be able to get them to fix this for free.

I haven't found any other information online about this problem. I can't be the only one, though.

Stuff I've tried:

- Changing from 1080p to 1080i, 720p, etc. -- no change.

- Jiggling the entire cable, in case there's a short.

- Unplugging/re-plugging in the video cable.

- Performing the "Reset Video Settings" trick per Microsoft's KB article.

How *$()@% frustrating is this? Microsoft really doesn't get it sometimes.

Update: According to users who replied to my XBox.com forum post, the problem appears to be that the GPU is either overheating, or beginning to break away from the motherboard. This is similar to what causes the "Red Ring of Death" errors, but not the same. I think I'm going to just have to bite the bullet and pay for repairs, even though this is clearly a design flaw, and not a problem I caused.
