- The Info Menu appears on the left side of the screen by pressing the “I” information key. The selected submenu appears to the right next to the information menu.
- The green marker is moved to the relevant sub-menu item with the {_ / _} buttons. The marker moves to the selected sub-menu by pressing the { _ } button.
- Select < back with the {_ / _} buttons to return to the info menu from the various sub-menus. The marker moves back to the info menu by pressing the { _ } button.

Settings in service mode
menu:
- Version number: mark the software version. For a new initialization of the NVM values, without adjusting the geometry settings, the version number must be changed, stored, leave the service mode and start it again using the mains switch.
- NVM reset initializes all NVM values in the eeprom IC905 with geometry values. Setting to on, store, leave the service mode and start it again using the mains switch. Before the initialization you can write the service mode parameters in the alignment table.
The
following settings should be checked after each initialization and, where
necessary, set properly again:
picture size: 4:3 or 16:9 picture tube
picture tube: type of the picture
tube
Important: Change this value only,
if is absolutely necessary. A change is
programming all parameters of the picture tube. If you can`t find the correct
type of the picture tube, select “USER PICTUB” and set all parameters manual.
TO ENTER SERVICE MODE
- Before activating service mode set suited test pattern. Set medium brightness, color, contrast, sharpness, noise and picture mode.
- A standard 4:3 test pattern is necessary for the geometry adjustment. The chassis for 16:9 requires a 4:3 test pattern covering the entire area to be set in the decoder mode, thus creating a horizontal extension (horizontal ellipses).
To enter service mode, press the
buttons "MUTE" "Red" (picture menu) and ‘TV’
on remote control
one after another.
KEY FUNCTIONS IN SERVICE MODE
Red button: select menu line or digit
Buttons ▲ / ▼ : select further parameters
Buttons ◄ ► : change parameters
OK button: store the changes
TV button: leave Service Mode
Child lock-code global ON / OFF
OFF: During the search operation all
channels are not "prepared" for a possible activation of the
childproof lock and have to be individually set.
ON: During the search operation all
channels are "prepared" for a possible activation of the childproof
lock.
Child lock-code reset
ON: To deactivate the childproof
lock, set to ON.
After switching on with the mains
switch again, the childproof lock is switched off.
G2 [screen] adjustment
After an operating time of approx.
30 minutes set a gray bar test pattern. Actuate the G2 controller to set the
cathode with the largest value (measured) in such a way that the measured value only just changes
from a single –digit numerical value to a two-digit value.
Focus adjustment
Set
a test pattern and set color, brightness and contrast to nominal value. With
Focus control set to optimum normal focus. For bi-focus tubes
(16:9/32"-tubes with separate focus block) adjust the left control (FOC-L)
so that horizontal lines are refocused to a minimum over the complete image
width in vertical direction. Adjust the right control (FOC-H) so that vertical
lines are refocused to a minimum in horizontal direction. The adjustment must
be repeated reciprocally.
Cut off / white drive
(black-white balance)
Cut off: Set the three cutoff values so that
the darker grey areas turn achromatic. The default values of the cutoff setting
points are 50. Leave the value of the cathode with the middle controlled value as it
is, set the two other cathodes.
White drive: The default values of the White
Drive setting points are 128. If the picture seems too “cold” reduce the white
drive blue setting point. If the picture seems too “warm”
turn the white drive red setting point back.
Hints for the real-flat picture tube
The surface of the screen is covered
with a laminated and 40% light-absorbent film with a hard coating. Under
no circumstances may this be damaged.
Under no circumstances:-
May the screen be wiped with
conventional glass cleaning fluid.
May the screen be brought into
contact with abrasive materials.
May soiling be removed by polishing
or scouring.
To clean off sticky
substances, the cloth can be moistened with acetone.
