Entering service mode on a TV provides different options than the typical user menu. For example, you can make advanced adjustments to the TV's calibration settings. Service mode is intended for trained professionals because making changes can cause permanent problems to your Panasonic Plasma if you don't know what you are doing. Therefore, do not enter service mode unless you know exactly what changes you want to make to your television.
Turn your Panasonic Plasma TV on.
Locate the "Volume Down" button on the front panel of the Panasonic Plasma. The button may be concealed by a thin plastic door beneath the screen that swings up to reveal the volume controls, channel control buttons and audio/video inputs. The "Volume Down" button is designated by a minus sign (-). Also, locate the "Status" button on your remote control. Once you have located those two items, proceed to step 3.
Press the "Status" button on your remote control three times while holding in the "Volume Down" button. The "Service Mode" menu now appears.
Make any changes you want in "Service Mode." To exit out of "Service Mode," click the "R" button on your remote control.
Never make changes in service mode unless you are a trained professional.
