For the customers in the Netherlands
Voor de klanten in Nederland

Hoe u de batterijen moet verwijderen, leest u in de tekst
van deze handleiding.

Gooi de batterij niet weg maar lever deze in als klein
chemisch afval (KCA).

Für Kunden in Deutschland

Entsorgungshinweis: Bitte werfen Sie nur entladene
Batterien in die Sammelboxen beim Handel oder den
Kommunen. Entladen sind Batterien in der Regel dann,
wenn das Gerät abschaltet und signalisiert “Batterie
leer” oder nach längerer Gebrauchsdauer der Batterien
“nicht mehr einwandfrei funktioniert”. Um
sicherzugehen, kleben Sie die Batteriepole z.B. mit
einem Klebestreifen ab oder geben Sie die Batterien
einzeln in einen Plastikbeutel.

1-4. Service Knowhow

1-4-1. After Replacing the Prism Block

1. Perform Section “2-2. V COM Adjustment.”

2. Perform the Look Up Table or 3D GAMMA data
writing of the Prism Block.

3. Perform Section “2-4. White Balance Adjustment on
Servicing.”

1-4-2. After Replacing the Board

. Refer to the cross table shown on right.
. There are no need to perform the adjustment when the board

other than the B board or C board had been replaced.

1) When Replacing the B Board

When the data before replacement can be read properly

1. Make a note of the data before replacement. After
replacement, write the data into the new board with
service mode.

2. If the white balance is extremely deteriorated, perform
the white balance adjustment (Refer to Section 2-4.).

When the data before replacement cannot be read

1. Perform Section “2-2. V COM Adjustment.”

2. Perform Section “2-4. White Balance Adjustment on
Servicing.”

3. Perform Section “2-5. Tilt Adjustment.”

2) When Replacing the C Board

1. Before replacement, unsolder the IC705 from the
replaced C board and then mount it to the new board.

2. Perform Section “2-2. V COM Adjustment.”

3. If the white balance is extremely deteriorated, perform
the white balance adjustment (Refer to Section 2-4.).

4. Perform Section “2-5. Tilt Adjustment.”

3) When Replacing the Other Board

There are no need to perform the adjustment.

W/B
Memory

Gamma memory is actualized through Gamma mode
functions’offsetting the output values to the Contrast and
Brightness devices.
When the power plug is connected to the power line
(Standby status), all data inside the internal ROM are
written into the NVM (Nonvolatile Memory). When the
power is turned to on, required data for the current picture,
such as status memory data, etc., are selected, and they are
written into the internal RAM.
When adjustment is carried out, adjustment data are
written into the NVM automatically (items on the user
mode) or by the trigger of memory operation (items on the
