1-6. Unleaded Solder
3) Iris Adjustment
Boards requiring use of unleaded solder are printed with a
lead free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come
printed with the lead free mark due to their particular size.)
: LEAD FREE MARK
m
. Be sure to use the unleaded solder for the printed circuit
board printed with the lead free mark.
. The unleaded solder melts at a temperature about 40 dC
higher than the ordinary solder, therefore, it is recommended to use the soldering iron having a temperature
regulator.
. The ordinary soldering iron can be used but the iron tip
has to be applied to the solder joint for a slightly longer
time. The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful.
1-7. Service Knowhow
1-7-1. 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.”
Preparation
1. Enter “34/Iris Adj.” in Other of Device Adjust.
2. Change the value of “34/Iris Adj.” from 0 to 1.
Adjustment
1. Set the value of “35/Open Reg” to 0 and check the
value of “37/Open Hall”.
2. Check the value of “37/Open Hall” while increasing
the value of “35/Open Reg”.
3. Check the value of “35/Open Reg” when the value of
“37/Open Hall” is decreased by 2 from the value of
step 1.
4. Save the value that is increased by 10 from the value
of “35/Open Reg” in step 3.
5. Set the value of “36/Close Reg” to 255 and check the
value of “38/Close Hall”.
6. Set the value of “36/Close Reg” to 0 and check the
value of “38/Close Hall” while increasing the value of
“36/Close Reg”.
7. Check the value of “36/Close Reg” when the value of
“38/Close Hall” is increased by 1 from the value in
step 5.
8. Save the value that is decreased by 14 from the value
of “36/Close Reg” in step 7.
Procedure after adjustment
1-7-2. After Replacing the Board

other than the C board had been replaced.
1) When Replacing the C Board
1. Before replacement, unsolder the IC1403 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 “3) Iris Adjustment.”
2) When Replacing the Other Board
There are no need to perform the adjustment.
1-20

C board is replaced and mount them on a (new) C
board.
3. Perform the iris adjustment in step 3) of Section 1-7-2.
4. Perform the VCOM adjustment in Section 2-2.
5. Perform the W/B adjustment when the W/B state is
remarkably bad.
6. Minimum voltage adjustment for fan 3 drive
1. Adjust the voltage so that pin 1 of the connector
CN1909 on the C board is within the following
specification.
Specification: 6.2 ±0.1 V
7. Maximum voltage adjustment for fan 5 drive
1. Enter “32: Fan3/Reg Max” in Other of Device Adjust.
2. Adjust the voltage so that pin 1 of the connector
CN1911 on the C board is within the following
specification.
