Purple/green rolling horizontal
bars and buzzing noise from the
TV speakers with Component
cable connection.
• Remove the left and right audio connections from the set-top-box. If the
buzzing stops, this indicates that the set-top-box has a grounding issue.
Replace the Component video cables with an HDMI connection.
The picture won’t display in full
screen.
• HD channels will have black bars on either side of the screen when
displaying up scaled SD (4:3) contents.
• Black bars on the Top & Bottom will be shown on movies that have
aspect ratios different from your TV.
• Adjust the picture size options on your external device or TV to full
screen.
Image Retention (Burn In) Issue.
• To minimize the possibility of screen burn, this unit is equipped with Pixel
Shift screen burn reduction technology. Pixel Shift lets you set the picture
so it moves slightly up and down (Vertical Line) and side to side (Horizontal
Dot). The regular, slight movement of the picture reduces screen burn in.
