The service mode on a Panasonic HDTV is fairly easily accessed by using the remote supplied with the unit. Adjustments allow more in-depth settings, inaccessible from the standard user menu. Although these settings have the ability to disable the set if maladjusted, the potential for far better image quality is attainable in the right hands. However, on a lower level, some useful items can be changed or disabled that do not require further access within the remaining lifespan of the set.
