CHAPTER 2 GETTING STARTED
Before Watching TV
Programs
• Your dealer should adjust the color convergence when your TV is delivered. However,
convergence may drift over time or if you move the TV. If you can see clear images on
the screen, skip this page.
To align the colors
This wide projection TV uses three
separate TV tubes; a red one, a green
one, and a blue one.
The red, green and blue images are
projected onto the screen where they
converge to form a full color picture.
You can see a clear picture when they
converge correctly.

To check and align the colors
1 Select an active channel and wait a moment for the picture to
stabilize.
Push the TEST button to set to the "TEST ON" position.
If alignment is correct, there will be one vertical and one horizontal
white line: so you don't have to align the colors.
