(1) If the convergence gets out of spec during servicing, call up the process mode and select the following sub-

jects.
Group

: NOKO

Subject

: R-CNV-H, R-CNV-V

G-CNV-H, G-CNV-V
B-CNV-H, B-CNV-V

(H: Horizontal adjustment, V: Vertical adjustment)

Adjust the above settings in the range of 0-4. When changing each setting from the initial setting of 2, however,
the 1280 x 1024 dot display area will have a fewer number of lines.

Example 1 : When the R-CNV-H setting is changed from 2 (initial) to 4, the number of lines will be from 1280 to

1278.

Example 2 : When the R-CNV-H, G-CNV-H and B-CNV-H settings are changed to 3, 3 and 4, respectively, the

display will be 1278 x 1024 lines. But when the above settings are switched to 2, 2 and 3, respec-
tively, the display will be 1279 x 1024 lines.

(2) When calling up the process mode, make sure the following appears onscreen.

Feed test pattern signal from 
PC.

Use specified cable.

Is specified cable connected 
between PC and projector?

Power circuit in trouble.

Is supply voltage as specified?

Check the connectors, starting 
from the input  circuit.

Does image appear?

Video input in trouble

Go to "Checking the video unit 
circuit".

Through-output in trouble

Through-output circuit in 
trouble.

Remote control in trouble

Go to "Checking the remote 
control".

Go to "Trouble shooting table 
for PC I/F unit ".

Go to "Lamp fails to light-up".

Is specified voltage fed to EA  
connectors?

Check the power circuit and its parts.

Are there signal inputs at pins (12), 
(31) and (37) of SC401?

Are there signal outputs at pins (7) of 
IC6014 and (7) of IC6015?

Check the input unit circuit (IC1401, 
IC1402, IC1403, IC1404, IC1405 
and its  peripheral circuits).

Go to "Checking IC803 
(RGB signal output circuit)".

Check IC6009, IC6011, 
IC6014, IC6015 and their 
peripheral circuits as well 
as switching circuit.

Is the lamp on?

Check the IC1403, IC1406 selector 
switch, terminal voltage and input 
circuit.

Is there video signal input at IC4001?

Check the low-pass and buffer 
circuits of Q4002, Q4003 and Q4004.

Are there signal outputs at pins (6) 
and (8) of IC4001?

Check IC4001 and its peripheral 
circuits (bias).

Check the low-pass and buffer circuits 
of Q6008 thru Q6014. Is the signal as 
specified?

Go to "Checking IC801 (RGB signal 
output circuit)".

Is there video signal output at pin (7) 
of IC1405?

Check Q4005 thru Q4008 and their 
peripheral circuits.

Check the data transfer and other 
performance at pins (17) and (18) of 
video IC803.

Go to "No colour or unusual tone", 
"No Y signal" or "Out of sync".

Are there output waveforms at pin 

1 

of Q6801, Q6802, Q6803?

Check Q6801, Q6802, Q6803 and 
their peripheral circuits.

Are there output waveforms at pin 
(8), (10), (12) of SC8404?

Check IC6801, Q6807, Q6808, 
Q6809 and their peripheral circuits.

Are there RGB output waveforms at 
pins (31), (32) and (33) of IC803?

Go to "Trouble shooting table for PC 
I/F unit".
