Problem
Possible Solution
There are black bars
to the right and left
of the picture
Wide screen TVs display 4:3 programs in this format unless set to Stretch. Turn
on the 4:3 OVERRIDE feature in the User Settings menu. This enables most
wide screen TVs to stretch the video to fill the screen (see your TV manual for
information about stretching 4:3 video).
If the RNG set-top is connected to a wide screen TV, verify that the TV TYPE is
set to 16:9 in the User Settings menu.
Many HD programs are broadcast in pillar-box format with black bars to the left
and right of the picture. These programs are broadcast in 16:9 HD formats even
though the video is not 16:9.
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 RNG set-top
is tuned to a 4:3 program.
Set the TV TYPE to 4:3 Pan-Scan. This enables the RNG set-top 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 wide screen 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 RNG set-top 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 the colors will not appear correctly on your TV.
The RNG set-top is
making a humming
noise.
The RNG set-top includes an integrated hard drive and a fan for cooling. During
normal operation, the RNG set-top 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 RNG set-top.
Please note the hard drive will stay on even when the RNG set-top is turned off
(standby).
