(to page 2).
Feed in a grey scale test pattern with burst.
White balance:
Central position.
Contrast:
Maximum.
Colour contrast:
Mean value.
Screen brighness:
Mean value.
Call up the "White level alignment" menu via "EASY
DIALOG" –> "Installation" (to page 2) –> "Dealer service
menu" –> "8500" –> "Picture settings".
Call up the "Picture tube type" menu via "EASY

service menu" –> "8500" –> "Special functions".
Feed in a transmitter picture.
Press and hold down the "PIP" button while switching on
with the mains switch.
Call up the "Screen geometry" menu via "EASY DIALOG" –>
"Installation" (to page 2) –> "Dealer service menu" –>
"8500".
Feed in a geometry test pattern.
Attention: The "Horiz. Pos." alignment influences the
horizontal phase. Prior to carrying out this adjustment, set
the picture width to minimum and correct the lock-in position
if necessary using the "H-Shift" plug.
Reset: The "Reset" field contains:
- either the optimum picture geometry data set at the
factory,
- or an average data record from the ROM if the set has
been started with the emergency data record.
After an incorrect alignment you may reload this basic data
at any time:
Call up the "Reset" menu via "EASY DIALOG" –>
"Installation" (to page 2) –> "Dealer service menu" –>
"8500" –> "Screen geometry".
Switch the set to channel position "AV5" and feed in a
geometry test pattern via the VGA socket.
Call up the "Reset" menu via "EASY DIALOG" –>
"Installation" (to page 2) –> "Dealer service menu" –>
"8500" –> "Screen geometry".
Call up the "TeleWeb" menu via "EASY DIALOG" –>

The channel positions 1…199 are adjusted at the same
time.
Adjust the values for red, green and blue so that the
picture becomes achromatic.
Set the picture type (T=Toshiba, P=Philips, V=Videocolor).
(This effects the peak beam current).
Adjust the vertical and horizontal PIP position so that the
small picture is not confined by the picture borders.
With the help of the user guide adjust the geometry values
first for the vertical deflection and then for the horizontal
deflection.
Only when this is done position the picture contents into the
centre of the screen. Re-adjust the picture width according
to the test pattern.
Saving:
The set value is saved by pressing the "yellow" button.
The picture geometry adjusts itself to the last saved value
