Normally a black and white picture is an indication of the cables being mismatched or connected to the wrong input. If the screen appears in black and white when a set-top is connected, it may be due to a poor HDMI cable connection. If the screen appears in black and white only in certain channels, it is likely an issue with the broadcast signal rather than the TV itself.

Before troubleshooting can be started, you will need to determine which type of cables you are using.
Is the TV currently on the Component Input?
If so, check the component connections on both the output device and the input of the TV. The colors should match. The component cables should have a total of 5 color coded connectors and they should be firmly connected to the output and input connection.Sometimes a loose connection can cause a black and white picture so you will need to check each connection on the back of the TV to ensure it is firm and secure.
You will also need to check the output device’s cables to ensure they are also firmly connected.
Check the various inputs on the television to see if the problem occurs with multiple inputs.
Select a Picture Mode that does not say User beside it. You may also need to perform a Picture Reset. If not, there could be a problem with the cable itself that is being used.
Connect the output device to the television with a different set of cables to determine whether or not the problem is with the output device itself.
