ADJUSTMENT INSTRUCTION
1. Application Range
This specification sheet is applied to all of the LED TV with
LC34N 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.
