ADJUSTMENT INSTRUCTION
1. Application Range
This specification sheet is applied to all of the LED LCD TV
with LC22E chassis.
2. Designation
(1) Because this is not a hot chassis, it is not necessary to
use an isolation transformer. However, the use of isolation
transformer will help protect test instrument.
(2) Adjustment must be done in the correct order.
(3) 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 specific designation.
(4) The input voltage of the receiver must keep AC 100-240
V~, 50/60 Hz.
(5) The receiver must be operated for about 5 minutes prior to
the adjustment when module is in the circumstance of over
15.
In case of keeping module is in the circumstance of 0 °C, it
should be placed in the circumstance of above 15 °C for 2
hours.
In case of keeping module is in the circumstance of below
-20 °C, it should be placed in the circumstance of above 15
°C for 3 hours.
[Caution]
When still image is displayed for a period of 20 minutes or
longer (Especially where W/B scale is strong. Digital pattern
13ch and/or Cross hatch pattern 09ch), there can some
afterimage in the black level area.
3. Automatic Adjustment
■ Enter Service Mode by pushing “ADJ” key,
■ Enter ADC mode by pushing “► key at “8. ADC Calibration”
■ There are 2 ways for ADC Calibration. ( OTP, External )
*. OTP mode
the manufacture line, OTP is used for ADC Calibration
automatically.
*. External mode
: Manual ADC Calibration. When OTP mode is failed, ADC
calibration should be “OK” by using External mode.
3.1. OTP mode
1. Change the ADC type “OTP” by using “►”key.
2. Enter “Start” key.
3. Check the sign “OK” below ADC type.
3.2. MAC address D/L, Widevine key D/L
Connect: PCBA Jig-> MTK Board 4pin -> RS-232C Jig->
RS-232C Port == PC-> RS-232C Port
Communication Prot connection
▪ Com 1,2,3,4 and 115200(Baudrate)
Mode check: Online Only
▪ Check the test process: DETECT → MAC → Widevine →
ESN → CNTV
▪. Play: START
▪. Result: Ready, Test, OK or NG
▪. Printer Out (MAC Address Label)
