MAIN MENU DEFAULT SETTINGS
A/V RESET DEFAULT SETTINGS
A/V Memory
Each of the external inputs has its’ own Audio/Video Memory.
A change in an A/V setting at a specific input is stored in memory for that
specific input.
A/V Reset
- The front panel AV Reset button initializes all A/V Memories.
- The AV Reset in the user’s menu initializes only the selected input’s A/V Memory.
LED BLINKING CODES
The “Power ON LED” provides an indication of the sets
operation, and the possible cause of a malfunction.
Initial Control Circuitry Check
- Immediately after the TV is connected to an AC power source: The LED flashes three times ... indicating the Microprocessor has initialized and is functioning properly.
- If the LED does not flash ... the Microprocessor is NOT functioning.
Error Code Operational Check
- Pressing the front panel “INPUT”and “MENU”buttons at the same time, and holding for 5 seconds, activates the Error Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem has occurred since the last Initialization.
- Note: The front panel buttons must used, NOT those on the Remote Control.
- The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
- The flashing then pauses for approximately 1/2 second.
- The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
- The Error Code is repeated a total of 5 times.
Error Codes
The Error Code designations indicating a malfunction, or no
malfunction, are listed below:
- “12”à indicates no error has occurred.
- “21”àRay Protect circuit.
- “22”àort Protect circuit.
- “23”àrizontal Deflection failure.
- “24”àrtical Deflection failure.
CIRCUIT ADJUSTMENT MODE
Most of the adjustments can only be performed using the
remote hand unit. Many of the adjustments must be performed in both the NTSC
and HD modes. Video/Color adjustments must be performed in the NTSC and HD
modes, and data must be preset in the 480P (DVD) and VGA modes.
ACTIVATING CIRCUIT ADJUSTMENT MODE
- Select the signal source (NTSC or HD).
- Press the "MENU" button on a remote hand unit.
- Press the number buttons "0", "1", "5", "7" in sequence. The screen will change to the Adjustment Mode.
- Note: Repeat steps 1 and 2 if the circuit adjustment mode does not appear on screen.
SELECTION OF ADJUSTMENT FUNCTIONS AND ADJUSTMENT ITEMS
- To select an adjustment item in the circuit adjustment mode, first select the adjustment function that includes the specific adjustment item to be selected. Then select the adjustment item. Refer to the following pages for the listing of adjustment functions and adjustment items.
- Press the "AUDIO" button on a remote hand unit to select an adjustment function. Each time the button is pressed, the Function changes in the following sequence:
- Press the “VIDEO” button to select a specific Adjustment Item. The Item number increases each time the “VIDEO” button is pressed.
- After selecting an adjustment Item, use the “ADJUST UP/DOWN” button to change data.
- Press “ADJUSTS DOWN” to decrease the data value.
- Press “ADJUSTS UP” to increase the data value.
Press, “ENTER” to save adjustment data in memory. The
character display turns red for approximately one second in this step.
Note: If the circuit adjustment mode is terminated without pressing,
“ENTER”, changes in adjustment data are not saved.
- Press the “MENU” button on the remote hand unit twice to terminate the adjustment mode.
- Note: The circuit adjustment mode can also be terminated by turning power OFF.
- Pressing “3”when in the Adjustment Mode toggles between NTSC, HD, 480P and VGA. However data changes are not automatically saved. Press, “ENTER”to save data before pressing “3”.
CONVERGENCE ADJUSTMENT
The Convergence mode is used to perform raster geometry
correction, and convergence adjustments. These adjustments must be made in both the SD (NTSC) and HD modes.
- Press MENU-0-1-5-9
- When the Convergence Mode is activated, the display below appears on a Green Crosshatch.
Selecting the HD or SD Mode
- Select the Signal Source before entering the Convergence Mode, either an NTSC or HD source.
- If the signal source is NTSC, the SD mode is activated.
- If the signal source is HD, the HD mode is activated.
- Activate the Factory Option Menu (MENU-0-1-7-0)
- Use the “Adjust” keys to select “DTV Port” and use the “Enter” key to change the setting from “AUTO” to “1080i”.
- Exit the Option Menu (Press MENU twice)
- Select the DTV Inputs as the signal source (INPUT button)
- Activate the Convergence Mode ... the Convergence mode will be in the HD mode and the internal crosshatch is displayed.
- After adjusting Convergence, be sure to set the DTV Port back to AUTO.
- Select an analog Input as the signal source (INPUT button)
- Activate the Factory Option Menu (MENU-0-1-7-0)
- Use the “Adjust”keys to select “DTV Port”and use the “Enter”key to change the setting from “HD”to “AUTO”.
- Exit the Option Menu (Press MENU twice).
Convergence Mode Functions
In the Convergence Mode there are three main Functions
(Categories).
- Pressing “6”activates CONV MISC
- Pressing “5”activates COARSE CONV
- Pressing “4”activates FINE CONV
This mode is used to preset data values controlling the
Convergence Generator, and to perform the HV Regulation adjustment.
- Use the VIDEO button to select an item.
- Use the ADJUST buttons to change data.
- NOTE: When Item “0 HVOL” is selected the screen goes black except for the data display. This occurs since a black screen is required when making the HV Regulation adjustment.
COARSE CONV (Press 5)
There are four Sub Functions in the Coarse mode, COARSE
GREEN, COARSE RED, COARSE BLUE and DF.
- COARSE GREEN .... used to make Coarse Raster Geometry Adjustments.
- COARSE RED ... used to make Coarse Red Convergence Adjustments.
- COARSE BLUE ... used to make Coarse Blue Convergence Adjustments.
- DF ... used to preset data values controlling the Dynamic Beam Focus circuit drive signal.
- Use AUDIO button to select a Sub Function
- Use the VIDEO button to select an Adjustment Item.
- Use the ADJUST buttons to change data.
FINE CONV (Press 4)
Sub Functions
This mode is used to perform Fine Raster Correction, and
Fine Red and Blue Convergence Adjustments.
There are three Sub Adjustment Functions, selected with the
AUDIO button:
- FINE GREEN .... a Green Crosshatch is displayed, to make Fine Raster Corrections.
- FINE RED .... a White Crosshatch is displayed, to make Fine Red Convergence Adjustments.
- FINE BLUE .... a White Crosshatch is displayed, to make Fine Blue Convergence Adjustments.
Cursor
In the Fine mode a Cursor is added to the Crosshatch. The
ENTER button toggles the Cursor between two modes:
- MOVE (blinking Cursor) .... use the ADJUST buttons to select any of 64 points on the Crosshatch.
- ADJUST (Non blinking Cursor) .... the ADJUST buttons adjust the active color at the current Cursor position, horizontally or vertically.
Cursor Coordinates
Specific intersections in the Crosshatch are assigned
vertical and horizontal coordinates. These are shown in the adjacent diagram.
The Cursor can only be moved to those positions that have coordinates assigned.
If the Cursor is at coordinates outside the screen area, the Cursor will not be
visible. Use the ADJUST buttons to move the Cursor to an intersection on the
screen.
Display
- The on-screen display changes in the Fine mode, as shown at the right. The display shows the vertical and horizontal data for the current Cursor Position, and the horizontal and vertical coordinates for that position.
Saving Data and Exiting the Convergence Mode
- Press MENU twice to exit the Convergence mode, data is automatically saved.
