Problem
Possible Solution
There are black
bars above and
below the picture
All 4:3 HDTVs display HD programs in letterbox format (black bars above and
below the picture) because of the shape of the display screen.
•
Turn on the 4:3 OVERRIDE feature in the User Settings menu. This
enables most standard screen TVs to display a full screen picture when the
QIP7000 series is tuned to a 4:3 program.
•
Set the TV TYPE to 4:3 Pan-Scan. This enables the QIP7000 series to
remove the black bars above and below the picture when possible.
Some SD programs are broadcast in the letterbox format with black bars
above and below the picture. Some widescreen TVs offer a zoom feature
that may be able to remove the black bars (see your TV manual for
information about zooming 4:3 video).
There are black
bars on all four
sides of the picture
This may occur on a 4:3 TV if the 4:3 OVERRIDE setting is OFF. To set 4:3
SD programming to fill the screen, depending on the capabilities of the TV,
set 4:3 OVERRIDE to 480i or 480p.
This may occur on a 16:9 TV if the active video for an SD broadcast is in
letterbox format. To confirm, wait for a commercial or look for a graphic,
such as a network logo. If the commercial fills the screen from top to
bottom, or the graphic appears below the active video, the program is being
letterboxed by the broadcaster. You can minimize this by activating the zoom
feature on the TV.
A broadcaster may include black bars on either side of a widescreen
broadcast. This is called a “hybrid” aspect ratio and results in a black border
surrounding the video on a 4:3 TV. Because this is part of the broadcast, the
QIP7000 series cannot correct the video. You may be able to minimize the
border using the zoom feature on the TV.
Colors do not
appear correctly
Be sure to match up each signal to the same YPbPr connection on the TV.
Otherwise, colors will not appear correctly on your TV.
The QIP set-top is
making a humming
noise
The QIP7200 includes an integrated hard drive and a fan for cooling. During
normal operation, the QIP7200 emits a low humming noise, similar to a
personal computer. The noise varies in volume occasionally when the speed
of the internal fan adjusts to changes in the temperature around the QIP set-
top. Please note the hard drive will stay on even when the QIP7200 is turned
off (standby).
