Home Theater Troubleshooting: Black Screen / No Picture

Symptoms

• Device: AV Receiver
• Issue: Black Screen / No Picture
• Connection Type: HDMI 2.0
• Signal Path: Through Receiver
• Resolution: 4K at 120Hz
• Enabled Features: HDMI features (e.g., HDR, VRR)
• Manufacture Years: 2020-2022

Possible Causes

1. HDCP Handshake Issues: HDCP (High-bandwidth Digital Content Protection) is a protocol that prevents copying of digital audio and video content as it travels across connections. A failure in the HDCP handshake could result in a black screen.
2. Cable Issues: Faulty or incompatible HDMI cables can cause signal loss.
3. Receiver Settings: Incorrect settings on the AV receiver may prevent video output.
4. Device Compatibility: Not all devices may support 4K at 120Hz over HDMI 2.0.
5. Power Issues: Devices may not be powered properly or may require a reset.

Step-by-Step Fixes

1. Power Cycle Your Devices

• Turn off your AV receiver, display device (TV/Projector), and any source devices (console, Blu-ray, etc.).
• Unplug all devices from the power source for at least 5 minutes.
• Plug them back in and power them on, starting with the source device, then the receiver, and finally the display.

2. Check HDMI Cables

• Inspect cables for any visible damage.
• Swap out the HDMI cable connecting your source device to the receiver. Ensure you use a high-speed HDMI cable rated for 4K at 120Hz.
• Test with a different HDMI port on the receiver and display if available.

3. Reset EDID Settings

• Access the receiver’s settings menu (refer to your user manual).
• Look for EDID settings and restore them to factory defaults. This resets the communication parameters between the devices.
• Save and exit the menu, then restart the devices.

4. Adjust Receiver Video Settings

• Go to your AV receiver’s settings.
• Ensure that the video output settings are correctly set for 4K and 120Hz.
• Disable any advanced features temporarily (e.g., HDR, VRR) to check if they are causing the issue.

5. Test Direct Connection

• Connect your source device directly to the display (bypassing the receiver) to check if the issue persists.
• If the display works directly, the receiver may need further troubleshooting or servicing.

Prevention Tips

• Use high-quality, certified HDMI cables that support 4K at 120Hz.
• Regularly update the firmware of your AV receiver and connected devices to ensure compatibility.
• Avoid overloading HDMI ports; use a quality switch or splitter if necessary.
• Maintain a clean setup by dusting off connectors and ensuring proper ventilation for all devices.
