Check
Is the picture low quality,
or "fuzzy", when you
YES
are expecting to see an
HDTV-quality picture?
NO
D
Can you see only regular
(analog) channels but not
YES
any digital channels?
Suggested solution
Some programmes may include "copy
protection" which means, if your set-top is
R
connected to your HDTV via the component
video jacks, the picture is downgraded to
standard TV quality. To prevent this from
happening, use an HDMI (high definition
multimedia interface) connection instead.
The bypass feature may be turned on. Check
in the Setup menu whether RF Bypass is On
R
or Off. If bypass is on, use the menu, or press
the BYPASS button on your set-top's front
panel, to turn the feature OFF.
