TROUBLESHOOTING
Should you encounter a problem when using your MHUB a soft power cycle or hard reset of the matrix should
resolve most issues.
TO PERFORM A HARD RESET:
Power down every device connected to the central hub: all input sources and all HDTVs. Now power down the
matrix itself. Leave off at the mains for at least ten to fifteen minutes. Finally connect and power on the matrix
again as if doing it for the very first time.
NO/INTERMITTENT PICTURE ON HDTV, BLOCKY IMAGES OR SPARKLES:
Find the fault
: Drop the output resolution of the source device down to 1080i or 720p. If the picture appears
correctly on the HDTV this indicates a bandwidth issue with the Cat cable run. The available bandwidth is too
low for 1080p transmission. Check that the Cat cable is not bent, knotted, kinked or distorted in any way- this
would prevent the high frequency signals from traveling throughout the intended length.
Ensure that the RJ45 connectors are fully inserted and click locked firmly into place to ensure perfect connector
connection.
THIS CAN BE CAUSED BY:
1.
Electromagnetic interference affecting the Cat5e/6/7 cable due to proximity to power lines.
2. Imperfect RJ45 connector termination
3. Use of wallplates or patch panels that cause too much bandwidth drop
4. Poor quality Cat cabling or internal cable strand breakages caused by poor production
5. Installation bending/strain/damage.
POSSIBLE FIXES:
Relocate cable run away from possible interference from power line (minimum 60cm)
Re-terminate RJ45 connectors or replace with better quality connectors
Remove wallplates and patch panels, replacing with direct cable runs and brush plates.
Upgrade to better quality Cat5e/6/7 cable.
