1. Chassis Introduction
2
This chassis is designed for European LCD TV with MPEG4. The main chip is
from MediaTek (MT5362 series). the MediaTek MT5362 series is a backend
decoder and a TV controller and offers high integration for advanced applications.
It combines a transport de-multiplexer, a high definition video decoder, an AC3
audio decoder, a dual-link LVDS transmitter, and an NTSC/PAL/SECAM TV
decoder with a 3D comb filter (NTSC/PAL).
The MT5362 series supports most Full-HD video decoder standards, including
H.264, MPEG4, MPEG2 and JPEG. The MT5362 series also supports MediaTek
MDDiTM de-interlace solution can reach very smooth picture quality for motions.
A 3D comb filter added to the TV decoder recovers great details for still pictures.
The special color processing technology provides natural, deep colors and true
studio quality video. Also, the MT5362 series has built-in high resolution and
high-quality audio codec.
The MT5362 series enables true single chip experience. It integrates high-quality
HDMI1.3, high speed VGA ADC, dual-channel LVDS, USB2.0 receiver and
multi-media decoder.
For DTV demodulation, the chip MT8295BNE is a companion chip combined with
MT5362 DVB serial chips to enable Common Interface (CI/CI+) function. It
supports DVB compliant Conditional Access Module (CAM) and PCMCIA type
memory cards. A NAND-flash-like or SPI-like bus bridge is built-in to perform the
communication between the host and the card through the Host Interface.
MT8295BNE supports one parallel or two serial or one parallel + one serial
MPEG2 transport stream (TS) inputs (2 x Host TS Input) from the front-end
demodulator or TS storage and a serial MPEG2 transport stream output (Host TS
Output) to MT5362 MPEG2 decoder.
The chassis is a high performance and fully integrated IC for multi-function LCD
TV with resolution up to full HD (1920X1080) and vertical frame up to 120Hz.
Also it’s a analogue/digital 2 in 1 TV receiver.
ATV System: PAL B/G D/K I, SECAM B/G D/K L/L
DTV System: DVB-T, DVB-C
This chassis includes 4 circuit assembly boards: main board, power board, key
board and IR board.
There are two kinds of power supply solution on this chassis, PWE4210 is for 40
and 46 inch TV, PWE3210 is for 32 inch TV.
PWE4210 outputs following voltages:
3.3VSB/0.2A is for standby power supply, 24V/1.0A is for main board, 24V/4.5A is
for inverter board.
PWE3210 outputs following voltages:
3.3VSB/0.2A is for standby power supply, 24V/3.5A is for main board and inverter

6. Alignment Procedure
29
INFO:
All tests and measurements mentioned hereafter have to be carried out at a normal mains
voltage (220 ~ 240 VAC),
All voltages have to be measured with respect to ground, unless otherwise stated,
All final tests have to be done on a complete set including LCD panel in a room with
temperature of 25+/-7°C,
The White Balance (color temperature) has to be performed into subdued lighted room after
at least 1 hour of warm-up/burn-in. This is applicable for both Alignment and Picture
Performance evaluation at OQA in order to be set fr ee of any t emperature dr ift (colorimetr y vs
time).
1. Electrical Assembly Alignment
1.1. Preconditions – DC/DC Check
Before power on, please check the board according to the relevant block diagram and
circuit diagram, and make sure that no serious error should destroy the board. For
example, the output of DC/DC and LDO should not be shorted to ground. Supply a suited
voltage and power on, then check the voltage according to the relevant block diagram ,
circuit diagram and voltage spec. the error should less than 5% .For example, the voltage
for main chip(DV33, AV33,DV18,DV11,etc.), the voltage for DDR (DDRV) , the voltage
for amplifier(AUDIO_PWR),etc. Only the standby voltage is necessary if there is no
software in the flash.
1.2. Panel ID check and modify
There is different ID stored in the NVM depended on different Panels. Modify it with Hyper
terminal if the initial ID or a wrong ID make the set can not display clearly. It can be
checked and modified in Factory menu->Feature->Panel ID if the set can display clearly.
The set should be restart if the panel ID is changed.
1.3. Functional Test
Once the boards (chassis, KB, IR, PSU…) and the panel are well interconnected,
connect all external generator devices to relevant inputs/outputs below acc ording to their
respective test patterns format and check picture content and sound quality accordingly

Audio tones can be defined by the factory (ie: 1KHz & 3KHz, sweep, …).
Picture video formats can be changed by the factory according to their own standard.
1.4. ADC Calibration
To ensure the ADC performance, the error of “generator + cable” must be less than 2%. The
following inputs require an ADC calibration for the time being.
VGA (skip this step if no VGA input on the chassis)
Provide a test signal 1024×768@60Hz with White Black squares.
Select the corresponding Factory Menu->
press ”OK” key on
Remote Control to start. Value of status will change to “OK” if succeed.
ADC Calibration-> Auto Color , then
CMP
Provide a test signal 720p@60Hz with 100% 8 steps Color Bar.
Select the corresponding Factory Menu->
press ”OK” key on
Remote Control to start. Value of status will change to “OK” if succeed.
ADC Calibration-> Auto Color , then
Scart RGB
Provide a test signal PAL 576i with 100% 8 steps Color Bar.
Select the corresponding Factory Menu->
press ”OK” key on
The mean of status value:
“NONE”= no input is successful in ADC calibration.
“OK”= current input is successful in ADC calibration.
“NOK”= current input is fail in ADC calibration.
“ALL”= all inputs required are successful in ADC calibration.
Remote Control to start. Value of status will change to “OK” if succeed.
ADC Calibration-> Auto Color , then
R Gain, G Gain, B Gain, R Offset, G Offset, B Offset in Factory Menu-> ADC
Calibration page
can be fine-tuned if necessary but not required.
1.5. DDC & EDID Test
The E-EDID data structure are according to VESA Enhanced EDID 1.3 (and EIA/CEA-861B
for HDMI).
Both VGA and HDMI have their own separate bin files:
For EDID check, it’s needed to check whether the correct EDID is downloaded by checking
corresponding EDID NVM Checksum or read them out to check bit by bit if it is in line with the
released EDID bin file.
1.6. HDCP Test
31
For HDCP compliancy, it’s needed to check whether the HDCP key has been well set.
1.7. CI+ Key activation and test (This step is only for the models with CI+
function )
Select factory men u-> Update CI+ Credential-> Update CI+ Crede ntial , then press ”OK”
key on
Cus Code(Custom Code), Serial Num display if succeed. Download the CI+ Key and try to
active it again if fail.
Remote Control to active the CI+ KEY. The Valid(CI+ state) state turn to “Yes” and

2.2. Entering to “P” Mode
Turned on the factory key to enter into “P” mode, The TV will display “P” in bottom left
corner in “P” mode.
2.3. White Balance Alignment
Make sure that the picture mode is “vivid”, enter to “P” mode (turned on the factory key) and
switch off “Pic. Enhance” in Factory Menu-> WD Alignment before white balance
alignment.
VGA,CMP,SCART RGB,DTV,CVBS_PAL Color Coordinates are relative to HDMI.
CVBS_SECAM and CVBS_NTSC Color Coordinates are relative to CVBS_PAL.
Warm and Cool Color Coordinates are relatives to Normal mode.
