2.2 The power supply should keep the rating voltage 110~240 VAC 50 / 60 Hz。
2.3 Ambient conditions: All the standards are measured under following conditions without other
specification.
1)Ambient temperature : 25 ℃
5℃
2)Relative humidity : 60 %
20 %
2.4 If no prior notice, the TV set should work for more than 20 minutes before adjustment.
2.5 Equipments needed
-- Multimeter

IF no extra specify, the standard input COLOR BAR PATTERN signal is 60 ~ 80 dBu from factory
centre or PM5418 signal generator
3. Software
3.1 Instructions
This chassis uses FLASH ROM to memory the program, and it can be re-rewritable.
The program is related to chassis function, the chassis with different functions should use different
program edition.
4. Chassis checking
4.1 The upside of the chassis should be clear and no short or open circuit, no missing components or
wrong polarity components insertion.
4.2 Check the input and output pins of 24V,12V,5V,3.3V，1.8V,regular IC (U23，U31，U32，U22，U24
，U21),confirm no short circuit to GND
4.3 Connect the chassis to LCD panel and the power supply ,confirm 5V,3.3V,2.4V,1.8V from any
regulators are OK.
4.4 Confirm OSD is OK, blue back appears without signals.
4.5 Confirm remote control functions and all collation keys control functions are OK.
4.6 Check searching function, save every factory TV signal, confirm the pictures in every system (PAL/
BG/DK/I，SECAM L/L') are OK.
4.7 Confirm HDMI1/HDMI2/SCART1/SCART2/SCART3/YpbPr/picture and sound in/output are OK,
confirm the picture and sound from PC are OK.
4.8 Confirm TELETEXT is OK.
4.9 Set into the whole machine, enter the aging line, set the TV to snowflake points state in the line.
5. Complete check
5.1 Check the pictures and sound in every system (PAL/BG/DK/I，SECAM L/L')are OK, check the picture
and sound under weak and strong signal, check picture in low and high voltage power input mode.
5.2 check NICAM function
5.3 Confirm teletext function is OK.
5.4 Confirm HDMI1/HDMI2/SCART1/SCART2/SCART3/YpbPr/picture and sound in/output are OK,
-18-
Service Adjustments
confirm the picture and sound from PC are OK.
5.5 C heck the remote control and the KYE-press can work normally, make sure it can make the TVset
enter the standby mode and return to the normal mode. Check the sound and picture can be adjusted
normally. Check the sound and picture ,make sure it can be adjusted normally.
6. Final setting
① PICTURE

※ special items set as the BUYER'S requirements。
7. Others
7.1 Because the LCD panel is high-tech product, please don't pull, crush or drop it, Please don't use the
cloth that with high humidity to clean it, because the moisture may lead short. You can use some soft
things to clean it, such as glasses cloth and camera lens
7.2 please pay attention to the high voltage in the INVERTER module output of the core. (About540Vrms
@60KHz)
7.3 Because the power supply id inside, please pay attention to the 220VAC.
