Troubleshooting

Should you encounter a problem when using your matrix a soft (power cycle) or hard reset of the unit

should resolve most issues.

A separate troubleshooting infosheet may be available for more complex issues. If you do not resolve

your issue after reading this email sales@antiference.co.uk with as much information about your set-

up and the symptoms as possible.

To perform the hard reset see page 8

ISSUE: No/intermittent picture on HDTV, blocky images or sparkles

Fault finding: 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 that would prevent these high frequency signals from traveling throughout the

intended length.

Ensure that the RJ45 connectors are fully inserted and click locked into place firmly and securely to

ensure perfect connector connection.

This can be caused by:

• Electromagnetic interference affecting the Cat5e/6/7 cable due to proximity to power lines.

• Imperfect RJ45 connector termination

• Use of wallplates or patch panels that cause too much bandwidth drop

• Poor quality Cat cabling or internal cable strand breakages caused by poor production

• 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.

ISSUE: IR control not working, or only working intermittently

Fault finding:

• Check the batteries in your remote control.

• Check that only IR cables labelled RX are connected to the TV Receivers, and TX to the

central hub.

• Double-check and reposition the IR TX emitters so they are directly in front of and approx 1”

from the IR receiving windows on the source devices.

• Connect each IR cable one at a time until the last IR cable connected introduces the fault.

Once discovered contact Antiference for a replacement IR cable
