VPL-HS60/HS51A

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 recom-
mended 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.

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

2.

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

3.

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

. Refer to the cross table (page 1-21).
. There are no need to perform the adjustment when 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.

Enter “34/Iris Adj.” in Other of Device Adjust.

2.

Change the value of “34/Iris Adj.” from 0 to 1.

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 100 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 2 from the value in
step 5.

8.

Save the value that is decreased by 11 from the value
of “36/Close Reg” in step 7.

1.

Reset the value of “34/Iris Adj.” to 0.

2.

Save the value in the memory.

1.

Enter “27:Fan/Reg Adj.Cont” in Other of Device
Adjust.

2.

Change the value of “27:Fan/Reg Adj.Cont” from 0 to 1.

1. Maximum voltage adjustment for fan 1 drive
1.

Enter “28: Fan1/Reg Max” in Other of Device Adjust.

2.

Adjust the voltage so that pin 1 of the connector
CN1907 on the C board is within the following
specification.
