This problem has been getting worse over the past couple weeks...
I first noticed it playing Fable, but it is always there, on the dashboard, any game or app I run. It appears as though some pixels are 'stuck' or dead, for instance a dark video or screen will be displayed, and there will be 10-15 little white pixels throughout the screen.
During video it produces a sort of sparkle effect... very subtle, but it has been getting worse.
I know it's not my cables, or any of the software, or the display device for that matter (have trying other cables, games in other xboxes, and xbox on different displays)
I couldn't find anything in the forums previously posted about this, I'm curious if it's either my GPU or my motherboard going out.
Has anyone experienced this or does anyone have advice??
