ADJUSTMENT INSTRUCTION
1. Application Range
This specification sheet is applied to all of the LED LCD TV
with LC22E chassis.
2. Designation
(1)
ecause 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.
(4) The input voltage of the receiver must keep 100~240V, 50/60Hz.
(5) The receiver must be operated for about 5 minutes prior to
(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.
(3) The adjustment must be performed in the circumstance of
25 ±5 C of temperature and 65±10% of relative humidity if
there is no specific designation.
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.
3.1 Main PCB check process
3. Adjustment items
4.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
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.
