Wrong colors or erratic video on screen
Problem: During the Media Center optional setup, if your display uses a component video connection, the
wizard may change the display color depth and show wrong colors or erratic video. This may occur if you select
a resolution that is not supported by your TV/Display. The component video cables might not be plugged in
correctly.
Solution: If the colors look wrong, or the video seems erratic, do the following:
1 See “Check component video” on page 23.
2 See “Correcting an extended blank screen with component video out” on page 25.
Line at bottom of the screen
