FUNCTIONS WHEN ENTERING THE SERVICE FACTORY MODE
The settings for the
following functions are set to OFF when Service Factory mode is entered (including
when the “FAY” command is received) :
User data will be treated as follows:
- User data on picture-quality and audio-quality adjustments are not reflected, and factory-preset data are output (user data will be retained in memory). When the unit enters Service Factory mode, the current audio-quality adjustment data will be still be retained in memory.
- User-setting data will be applied to the various settings (items on the menus), signal formats, and the items that are associated with path change (HDMI settings, etc.).
- Data on screen (i.e., screen position; meaning clock dividers, and not including data on screen size). Are reset to the default values (data stored in memory will be retained). Screen size will be retained.
The keys labeled with the same names on the service remote
control unit have the same functions as those of the supplied remote control unit.
For the keys not
provided on the supplied remote control unit, see the explanations below:
PROTECTION FUNCTIONS
HIGH-TEMPERATURE PROTECTION FUNCTION - 1
The panel temperature (TEMP1) reaches 70 °C, the limit for
the maximum count of plasma discharge will be gradually decreased to lower the
temperature of the panel.
- This function is activated based on the TEMP1 temperature.
- The limit for the maximum count of plasma discharge will be decreased 8 per 5 seconds.
- The lowest limit for the maximum count of plasma discharge is about 700.
- The maximum count of plasma discharge will begin to increase gradually if the panel temperature falls to the specified temperature.
HIGH-TEMPERATURE PROTECTION FUNCTION - 2
If the panel temperature (TEMP1) reaches 65 °C, the
plasma-discharge count that is determined based on the input APL will be
decreased. In actual operation, the ABL adjustment value will be offset.- This function is activated based on the TEMP1 temperature.
- The ABL adjustment value will be decreased by one step per 30 seconds.
- The ABL adjustment value will begin to increase gradually if the panel temperature falls to the specified temperature.
PANEL PROTECTION FUNCTION-1 [Protection against still picture]
If a still picture is displayed for 3 minutes or more, the
limit for the maximum count of plasma discharge will be gradually decreased to
minimize the effects of phosphor burn.- This function is activated after detection if the displayed picture is still (the picture will be considered to be still if only the mouse cursor is moved).
- The limit for the maximum count of plasma discharge will be decreased 8 per 5 seconds.
- The lowest limit for the maximum count of plasma discharge is about 700 (it takes about 15 minutes to reach the lowest limit, although the required time varies depending on the displayed picture).
- The maximum count of plasma discharge will begin to increase gradually if the displayed picture is changed to animated picture.
PANEL PROTECTION FUNCTION-2 [SCAN IC Protection]
If a particular load is applied to the SCAN IC, the limit
for the maximum count of plasma discharge will be gradually decreased.
Note: How to decrease the brightness level in this function
is the same as in high-temperature
protection function 1
PANEL PROTECTION-3 [Protection against panel cracking]
A bright window, as shown in the figure on the right, on the
screen increases the heat of the panel. If such a pattern is recognized on the
screen, the limit for the maximum count of plasma discharge will be gradually
decreased.
Note: How to decrease the brightness level in this function
is the same as in high-temperature protection function 1
