What it means
Panasonic explains that panel maintenance turns the screen off and adjusts the panel to prevent image retention. There is a normal, automatic maintenance of about 10 minutes and a regular one of about 80 minutes; when regular maintenance is needed, a message appears after turning the TV off with the remote. During the process the LED turns orange and a white horizontal line may appear for a while, which Panasonic says is not a malfunction. Turning the TV on cancels it. The message alone never proves that the panel is defective.
