RGB Color
NOTE: Displaying an anomaly in this diagnosis screen is not necessarily a failure.
This screen verifies that the ODMD (TM) is displaying the RGB (Red, Green, and Blue) components properly. The three primary colors should all appear without distortion. The combination of all three should produce a central white section.
The diagnostic screen is displayed in full screen mode when you touch the screen. To return to the previous screen, touch the screen again.
Color Pattern
NOTE: Displaying an anomaly in this diagnosis screen is not necessarily a failure.
The screen shows the colors being used for the menu screens. This is for factory use only. To check the color signal, use the RGB Color diagnosis.
The diagnostic screen is displayed in full screen mode when you touch the screen. To return to the previous screen, touch the screen again.
Gray Tone
NOTE: Displaying an anomaly in this diagnosis screen is not necessarily a failure.
This screen checks problems with contrast in 32 gradations. You should be able to see the changes from bar to bar across the scale. It is normal for the two bars on either side to appear the same.
The diagnostic screen is displayed in full screen mode when you touch the screen. To return to the previous screen, touch the screen again.
White Raster
NOTE: Displaying an anomaly in this diagnosis screen is not necessarily a failure.
This screen checks for pixels that may be dead (off). The entire display must be white.
The diagnostic screen is displayed in full screen mode when you touch the screen. To return to the previous screen, touch the screen again.
Black Raster
NOTE: Displaying an anomaly in this diagnosis screen is not necessarily a failure.
This screen checks for pixels that may be stuck on. The entire display must be black.
The diagnostic screen is displayed in full screen mode when you touch the screen. To return to the previous screen, touch the screen again.
Touch Panel Check 1
The panel touch sensing system consists of a touch sensitive resistive membrane covering the display. The screen has to be physically touched to make it work. The display has the capability of 800 touch locations (left to right), and 480 touch locations (top to bottom). The upper left hand corner is position (0, 0) and the lower right hand corner is (800, 480) as displayed. Touching anywhere on the screen displays the coordinate of the location, and cause the place you touch to display a + icon. If any area of the screen either does not respond, or responds at some other location when touched, do a battery cable reset, and recheck. If the results are the same, replace the ODMD(TM) panel .
NOTE:
- Unlike earlier screens that used infrared sensors, direct sunlight does not affect this test.
- A box appears after you touch the screen.
Touch Panel Check 2
If you touch any icons on the screen, the icon color changes while pressing the icon. If any icons on the screen do not respond, do a battery cable reset, and recheck. If the results are the same, replace the ODMD(TM) panel .
Touch Calibration
The panel touch sensing system consists of a touch sensitive resistive membrane covering the ODMD (TM). The screen has to be physically touched to make it work. The display screen uses a touch sensitive membrane. This means that every location of the entire surface of the display is touch sensitive. This diagnosis allows alignment of these touch locations with the location of the buttons images on the screen.
This should never need adjustment, and is used only by the factory to adjust the touch locations for parallax (the touch locations appear different when viewed at an angle). If you are directed to make an adjustment by the factory or other service information, follow this procedure:
- The screen consists of the + icons. Select Start, and long press the center of the five + icons on order 1
- To store any changes you make, Select Set.
- Select Return to exit the diagnosis.
