Question:

What steps should be taken to determine whether the issue with colors on the TV is due to a defective input on the TV or a defective output on the external device?

Answer:

To find out if the issue is caused by a faulty input on the TV or a defective output on the external device, follow these steps:

Test a different device using the same input on the TV (e.g., if you're experiencing color issues with your cable set-top box connected to HDMI 1, disconnect it and connect a Blu-ray player to HDMI 1).

If the color problem doesn't occur with the second device, the original device has a defective output and needs servicing.

However, if the color problem persists with the secondary device, the TV requires service to fix the defective input.

Terms:

Defective Input - A malfunctioning input connection on the TV causing issues when devices are connected.

Defective Output - A malfunctioning output connection on an external device causing issues when connected to the TV.

Color Problem - Issue with the display of colors on the TV screen, possibly due to a fault in the input or output connections.
