Troubleshooting
TUNING CABLE CHANNELS
Tip:
The 232-ATSC+ will skip encrypted channels automatically when you activate a channel scan
Tip:
You can skip scanning analog channels by pressing
Select
after you start the scan.
Symptom: Channel ID is in XX-XX form, not cable box Guide form
Cable boxes translate the actual channel #s into a virtual Channel Guide, using channels 2
– 900, or more.
The actual (physical) channels have IDs in XXX-XX form, just like off-air channels. Non-
cable HDTV tuners like the ATSC or LCD TVs don’t provide Guide features, so the channels
will be displayed in their native, physical major-minor channel form.
Some cable franchisees have a listing by physical channel, many do not. You can press the
INFO button on the HD2-RC remote to view the channel name.
POWER/VIDEO OUTPUT
Symptom: Tuner appears to be on, channel display is lit, but unresponsive, no video/audio out
This often occurs when a 232-ATSC+ is used to replace an old 232-series analog tuner.
The solution is to not use the old 500 Ma power supply, and use the 1.5 Amp power supply that
comes with the ATSC. The old supply has enough juice to light up the front panel LEDs, but nothing
else.
Symptom: No video on Component Out
The RGB and Component outputs are switchable, and the tuner ships set to RGB. Use Front Panel
Mode, next section to switch the HD analog video to Component.
HDMI
Symptom: No Video or Signal
Most monitors accept HDMI in the RGB and Component color space, but there are exceptions. Try
switching from RGB to Component (Front panel mode 48).
Switch between 720p and 1080i, or down to 480P or 480i for old DVI sets. (Front panel mode 49)
If you’re connecting via a Cat5 interface, HDMI receiver, or switcher, some delay the HDCP signal
slightly out of range. Call CR Support on how to extend the delay on HDMI.
Symptom: No audio or fluttering sound in display speakers connected via HDMI
Change ATSC digital audio to PCM or PCM variable (most displays do not use Dolby 5.1)
RGB/Component
Symptom: No RGB or Component Video output
Check the RGB or Component output setting in Front Panel mode 48 (48.0 is RGB, 48.2 is Component).
Symptom: No output display on VGA input
Some monitors or projectors do not support 1080i or 720P operation on the RGB port. Set resolution in Front
Panel mode 49 (49.2 for 480P).
Composite Video
Symptom: Composite video out has small image in 16:9 setting, analog channels
For a 4:3 set, tune to an analog channel and press RATIO on the remote to set to 16:9. Image will
fill left to right, you’ll always have a black band top and bottom.
Set to 4:3 if you’re only feeding video to 4:3 TVs.
Set output ratio on a digital channel as well - this a different setting than for analog channels.
If the tuner is used for 16:9 displays and analog TVs, choose the best setting for the widescreen,
and the NTSC will have to be a compromise. Most of the time, setting the RATIO while tuned to an
analog channel and again for a digital channel will provide the best result.
