Control4 and Crestron Touch Screens Not Connecting

Control4 T4 Series and Crestron TSW touch screens are professional home automation controllers that require dealer configuration. This guide covers common user-level troubleshooting for these systems.

Touch Screen Not Powering On

Symptoms

• Screen completely black
• No LED indicators
• Screen flickers then goes dark

Solutions

1. Check power - Verify PoE (Power over Ethernet) switch is powered and providing power to the panel.
2. Test ethernet cable - Replace ethernet cable if suspected of damage. Use Cat5e or Cat6.
3. PoE requirements - Control4 T4 requires 802.3at PoE+. Crestron may require 802.3af or higher.
4. Power cycle - Disconnect ethernet for 30 seconds, then reconnect.
5. Contact dealer - These are dealer-installed systems. Contact your integrator for hardware issues.

Touch Screen Not Connecting to Controller

Symptoms

• "Not Connected" message displayed
• Control functions unavailable
• Screen shows but can't control devices

Solutions

1. Check controller status - Verify the main Control4 EA/CA controller or Crestron processor is powered and online.
2. Network connectivity - Touch panel must be on the same network/VLAN as the controller.
3. Restart panel - Access settings menu and restart, or power cycle via PoE switch.
4. IP addressing - Check if panel has valid IP address. DHCP issues are common.
5. Firewall rules - Enterprise networks may block required ports. Consult with IT and dealer.

Solutions

1. Clean screen - Use a soft, dry microfiber cloth. Avoid cleaners with ammonia or alcohol.
2. Recalibrate touch - Access settings menu and run touch calibration if available.
3. Screen protector - Remove third-party screen protectors that may interfere.
4. Check for damage - Physical damage may require dealer replacement.

• Intercom audio one-way or missing
• Video feeds black

Solutions

1. Camera connectivity - Verify camera is online and accessible on the network.
2. Bandwidth - Video streaming requires adequate network bandwidth to the panel.
