7. PCMCIA CARD Check
You must adjust DTV 29 Channel and insert PCMCIA CARD
to socket.
- If PCMCIA CARD works normally, video signals will appear
on screen.
But it works abnormally, “No CA module” will appear on
screen.
[ Caution: Set up “RF mode” before launching products.
8. POWER Supply Unit PCB Ass’y 
Va/Vs Voltage Adjustment
Caution: Both Vs and Va voltage adjustment are necessary.
8-1. Va/Vs Adjustment Procedure
(1) Connect positive(+) terminal of DMM to Vs/Va pin, connect
negative(-) terminal to GND.
(2) Turning ‘Vs/Va Adjust’ and adjust Vs/Va voltages to a
value which is written on a right/top label of a module.
(deviation ; ±0.5V)
[Caution]
- Each Power Supply Unit PCB assembly must be checked by
check JIG set. (Because power PCB Ass’y damages to PDP
Module, especially be careful)
- Set up “RF mode(noise)” before a voltage adjustment.
- Test equipment: DMM 1EA
9. White Balance Adjustment
Caution: Press the POWER ON KEY on R/C before W/B
adjustment.
O
Test Equipment
Color Analyzer (CS-1000, CA-100+(CH.10), CA-210(CH.10))
O
Please adjust CA-100+ / CA-210 by CS-1000 before
measuring
You should use Channel 10 which is Matrix compensated
(White, Red, Green, Blue revised) by CS-1000 and adjust
in accordance with White balance adjustment coordinate.

<Notice> Module Heat-Run Condition for W/B
(1) The adjustment must be performed in the circumstance of
25 °C ± 5 °C of temperature and 65 % ± 10 % of relative
humidity if there is no any specifics.
(2) Before an W/B adjustment, the module which will be used
should be placed in the circumstance of 15 °C ~ 25 °C for
above 2 hours.
(3) If a module was placed in the circumstance of below 15°C,
it should be placed in the circumstance of 15° C ~ 25 °C
for above 2 hours or be run for above 5 minutes in an
aging environment of 60 °C.
(4) Before an W/B adjustment, TV set should be run for 5
minutes at least.
10. Serial Number Download
10-1. Download Procedure
(1) Press  “Power on” button of a service R/C.(Baud rate :
115200 bps)
(2) Connect RS232-C Signal Cable.
(3) Write Serial number through RS-232C.
