Most of the alignments for this chassis are software-driven.
Most of the alignments must be accessed and modified through the front panel service mode.
Entering the TV Service Mode Using the Front Panel Controls
1. Press and release the POWER button to turn the instrument off.
2. Wait 10 seconds before trying to enter the Field Service Mode.
3. Press and hold the VOLUME DOWN and CHANNEL DOWN buttons for at least 8 seconds.
4. The instrument will switch on and come up with the field service main menu on the screen. LED will illuminate
before the picture comes up.
The instrument should display the following menu:
The CH /\ and CH \/ buttons on the front panel are used to navigate up or down in the menu.
The VOL + and VOL - buttons on the FPA are used to select a menu item or decrease or increase a value in a selection list.
NOTE: Before the Field Service Mode is exited; you must check STORE or all changes to alignments will be lost.
The remote control can also be used to navigate the field service mode.
· Clear button: When this button is pressed the Field Service Mode disappears and the every-day TV functions are available.
· Menu button: To re-enter the Field Service Mode, make a long press on the Menu button. The service technician re-enters in the same menu point where he left the Field Service Mode.

Common features found in the submenus
Return: The submenu is closed and the main Field Service Mode menu appears.
Defaults: The default values for the current menu are copied from ROM to RAM.
Note: If Default is checked a complete realignment of that particular menu is required.
Store: All current values from a menu group are stored into memory.
Restore: The last stored settings for the menu displayed are copied from NVM to RAM.
In Level 1 and 2, Press OK to select the color to be aligned. The position of the adjustment point can adjusted using the navigation keys (up, down, left and right) on the remote. Press the 2 key of the remote to move to the next adjustment point. Press the EXIT/CLEAR key to exit when completed.
Level 3 alignment works simular to Levels 1 and 2. The only difference, to move to the next adjustment point press 2(up), 8 (down), 6 (right) and 4 (left) on the remote unit.
when completed with convergence, press STORE to save all changes.
Sensor Calibration is used to calculate a reference border for the autoconvergence photo sensors. Check the box to begin the process. Autoconvergence starts the autoconvergence process.
Defaults enters a default submenu. Checking the box loads a set of default values from the convergence backup NVM to the Convergence IC RAM. The box will remain checked until the value is changed or store or restore is pressed in the convergence submenu.
Note: Before the Convergence Alignement menu is exited, you must check Store or all settings will be lost.
