Asked Nov 17, 20180 views1 answer
I recently bought a Samsung TV model UN43NU6950F (serial number BZCF34CK913641). I have a USB cable connected to my Cox Communications box via HDMI, but I'm unable to receive any local channels. The TV displays a message indicating 'no signal.' I need help troubleshooting this issue.
Troubleshooting Samsung TV No Signal Issue with Cox Communications Box
If you're experiencing a "no signal" message on your Samsung TV (model UN43NU6950F) when trying to access local channels via a Cox Communications box, don't worry. This guide will help you troubleshoot the issue step by step.
Step 1: Check Your Connections
HDMI Connection
- Confirm the HDMI Cable: Ensure that the HDMI cable is properly connected to both the Cox Communications box and the HDMI input on your Samsung TV. Sometimes, a loose connection can be the culprit.
- Verify HDMI Port: If your Cox box is connected to HDMI2, make sure to select HDMI2 as the input source on your TV. If it is connected to HDMI1, select HDMI1.
USB Cable
- USB Cable Misunderstanding: It's important to note that a USB cable is not used for video input. Ensure that the Cox box is connected via HDMI only.
Step 2: Selecting the Correct Input Source
- Use the Remote:
- Press the Input or Source button on your Samsung TV remote.
- A menu will appear showing all available input sources.
- Select the HDMI port to which your Cox box is connected (e.g., HDMI1 or HDMI2).

Make sure your TV is set to the correct HDMI input. You can do this by pressing the "Input" or "Source" button on your remote and selecting the HDMI port where your device is connected. If your previous TV was set to HDMI 2, try switching to that HDMI option on your new Samsung TV.
If you're currently seeing "TV" as the input and don’t see any other HDMI options, check to ensure that your device is properly connected to the HDMI port. Sometimes, the cable can be loose or not fully inserted. If you’re using a cable box or disc player, make sure it’s powered on and functioning correctly.
If you still don’t see the expected options, you might want to try connecting your device to a different HDMI port on the TV, if available. This can help determine if the issue is with the port itself.
