Quick Summary
If you are experiencing issues with General devices, typically related to home theater setups, follow the checklist below to restore your connection.
Symptoms
- Black screen or "No Signal" message.
- Flickering video or audio dropouts.
- Device not recognized by TV or Receiver.
Troubleshooting Steps
1. Hard Reset All Devices
Unplug your TV and source device from the wall for at least 60 seconds. This clears the HDMI protection handshake cache.
2. Check Your Cables
Ensure you are using a Certified High Speed cable. Many generic cables fail at 4K/HDR bandwidths.
3. Adjust Settings
- TV: Ensure "Enhanced HDMI" or "Deep Color" is enabled on the input port.
- Source: Try lowering the resolution to 1080p to see if the signal returns.
Need More Help?
If replacing the cable doesn't work, the issue might be with the port itself. Try moving to HDMI Port 2 or 3.
