SUPPLEMENT

IMPORTANT SAFETY NOTICE
Proper service and repair is important to the safe, reliable operation of all
Funai Equipment. The service procedures recommended by Funai and de-
scribed in this service manual are effective methods of performing service
operations. Some of these service special tools should be used when and
as recommended.
It is important to note that this service manual contains various CAUTIONS
and NOTICES which should be carefully read in order to minimize the risk of
personal injury to service personnel. The possibility exists that improper
service methods may damage the equipment. It also is important to under-
stand that these CAUTIONS and NOTICES ARE NOT EXHAUSTIVE. Funai
could not possibly know, evaluate and advice the service trade of all con-
ceivable ways in which service might be done or of the possible hazardous
consequences of each way. Consequently, Funai has not undertaken any
such broad evaluation. Accordingly, a servicer who uses a service proce-
dure or tool which is not recommended by Funai must first use all precau-
tions thoroughly so that neither his safety nor the safe operation of the
equipment will be jeopardized by the service method selected.

ELECTRICAL ADJUSTMENT INSTRUCTIONS
General Note:
"CBA" is abbreviation for "Circuit Board Assem-
bly."
NOTE:
Electrical adjustments are required after replacing
circuit components and certain mechanical parts.
It is important to perform these adjustments only
after all repairs and replacements have been com-
pleted.
Also, do not attempt these adjustments unless the
proper equipment is available.

1. Auto Calibration (Black & White)
1. Operate the unit more than 20 minutes.
2. Input black raster signal fromonly Component AVIn-
put (2) video/Y jack (green). Do not input any signal
to Component AV Input (2) video/Pb or Pr jack.
3. Enter the service mode.
4. To enter the Auto Calibration (Black) adjustment
mode, press "2" button on the service remote con-
trol unit. If no signal, "No signal" appears on the
screen.
5. To start auto adjustment, press "CH o" button on
the service remote control unit.
6. Input white raster signal (100% or 110%) from only
Component AV Input (2) video/Y jack(green).Do not
input any signal to Component AV Input (2) video/Pb
or Pr jack.
7. To enter the Auto Calibration (White) adjustment
mode, press "3" button on the service remote con-
trol unit. If no signal, "No signal" appears on the
screen.
8. To start auto adjustment, press "CH o" button on
the service remote control unit.
9. Upon completion, wait for at least 5 seconds.
10. UnplugACcordandplugitinAC outletagaintoreset
then enter the service mode again.
11. Confirm thatboththe"Black Calibration : Complete"
and "White Calibration : Complete" are displayed
on the screen as shown in Fig. 4. If "Yet" is dis-
played instead of "Complete", repeat above steps.
2. White Balance Adjustment
Purpose: To mix red, green and blue beams correctly
for pure white.
Symptom of Misadjustment: White becomes bluish
or reddish.
Notes:
- Use service remote control unit.
- This adjustment should be performed in both Com-
ponent 2 mode and Video 1 mode. Adjustment in
Component 2 mode should be performed after com-
pletion of ADC calibration adjustment.
1. Operate the unit more than 20 minutes.
2. Input the gray scale pattern signal (5 scales) from
Component AV Input (2) video/Y jack.
3. Set the color analyzer to the CHROMA mode and
after zero point calibration, for high light adjust-
ment, bring the optical receptor to the 2nd scale as
shown below.
4. Enter the Service mode.

unit.
6. Press "4" button on the service remote control unit
for Red adjustment. Press "6" button on the service
remote control unit for Blue adjustment.
7. In each color mode, press "CH o/ p"button to ad-
just the values of color.
8. Adjust Red and Blue color so that the temperature
becomes 9200°K-5MPCD (x: 288 / y: 288) ±3%.
9. For low light adjustment, bring the optical receptor
to the 4th scale as shown below.
10. Press "1" button on the service remote control unit
for Red adjustment. Press "3" button on the service
remote control unit for Blue adjustment.
11. In each color mode, press "CH o/ p"button to ad-
just the values of color.
12. Adjust Red and Blue color so that the temperature
becomes 9200°K-5MPCD (x: 288 / y: 288) ±3%.
13. Check adjustment value in high light adjustment
again. If adjustment value is not within specifica-
tion, repeat steps 2-8.
14. To enter the adjustment mode in the Composite
mode (Video 1 mode), press "VOL p" button once
on the service remote control unit.
15. Input the gray scale pattern signal (5 scales) from
Composite AV Input (1) video jack (Video 1).
