5. If digital audio is to be connected (optional), connect an RCA lead between
the balun and the digital audio equipment at both ends.
6. Power-on the component video equipment. Check the image quality and refer
to troubleshooting if the image quality is unsatisfactory.
Troubleshooting
Video
Symptom Probable Causes Possible Solutions
No video No continuity in video link Verify cable continuity between
pairs of baluns.
No video Power off Check power supplies of video
equipment.
No video Improper connection or swapped
pairs Check that baluns are connected
to correct video inputs and
outputs.
Unusual colors Reversed polarity Check wiring and ensure
straight-through polarity.
Background pattern EMI interference Identify possible radiating
frequency sources (i.e.; wireless
LANs, switching power
supplies). Try to isolate them
from the video connection.
Use shielded twisted pair
grounded at both ends.
Weak contrast Exceeded distance Verify cable grade. Use higher
grade cable if necessary.
Increase contrast on monitor.
Weak contrast Unusual link attenuation Verify cable distance using
ohmmeter or cable tester.
Image not stable Defective link or equipment Verify video equipment interface
integrity.
Horizontal bars moving
slowly Substantial crosstalk between
multiple video sources Consecutively turn off other
video sources to determine
which video source is the cause
of interference.
Snowy picture Distance is near limit Verify cable grade. Use higher
grade cable if necessary. Reduce
color intensity at monitor.
Rolling horizontal bars or
other interference Improper grounding Confirm that either the send or
destination side is grounded. If
the source device, cable run, and
output device are all floating,
ground the chassis of the source
or output device.
Smearing
Exceeded distance Verify cable grade. Use higher
grade cable if necessary.
Digital Audio
Symptom Probable Causes Possible Solutions
No audio Distance exceeded Verify cable length between the two
baluns.
No audio Split pair Check if the UTP pairs are split and
correct. Each signal pair must be
twisted.
No audio Power-off. Check power supplies of digital audio
equipment.
Missing channels Cabling problem between
the decoder/amp and the
audio speakers. Check audio speaker cabling. Verify
Content is multi-channel and decoder is
working when attached straight through.
Noise, static EMI interference. Check that wiring is not too close to
transformers and ballasts.
Noise, static Distance exceeded or
unusual cable attenuation Check cable distance and cable grade.
