Main Preinstall Function

Weather: Provides weather forecast for cities, and lets you know real-time weather.

TCL Voice: Use voice to control the Smart TV. By speaking towards the mic of a smart

phone with Android system or an RCU with 2.4G function, we can let the TV perform the
related tasks(including changing channels, opening app and power off, etc.) For details, refer
to relevant introductions about this app on the screen.
[Note: This application is also included in nScreen. So before using it by phone, you should
enter the nScreen first.]

Face Recognition: Detect the face via the camera if there’s person watching TV. It can
automatically shut down the TV screen for energy-saving when you’re out of the camera’s
view. And it will turn on again when you’re back. Press “Left/Right” to switch among the menu
items. Press “OK” to enter the menu corresponding to the selected item. Press “Back” to exit,
and return to the previous menu. The specific operation can be carried out in accordance
with Help information in the menu.

[Note: To use this function, the TV must be connected with a camera.]

Gesture Control: Control the TV by simple hand movement. Just operate in accordance with

the prompts from the wizard, then you can experience TV control like changing channels,
turning pages, selecting an object and returning from an app or menu, etc.
[Note: To use this function, the TV must be connected with a camera.]

① Once AC Inputs, power board will provide a 3V3SB to the main board. Then
TV set enters standby mode, and the indicator on.Press the power button of
the remote control or the key board to turn on TV, then the Indicator off.

② Pin C3 of U400 sends out a high level, across R002, then directly send to
power board through pin10 of P001 on the main board, control the Power on.
Then the power board output 24V to main board and driver board.

----Backlight and Dimming

① Pin J4 of U400 sends out a high or low level, across R003, then

② Pin B8 of U400 sends out PWM signal, across R006, then directly
sends to power board through pin11 of P001 on the main board, adjust

MCU resets when MCU_RESET is high.

When 3V3SB comes, it charges C409
through R419, and Q401 turns on.
When the voltage of C409 is charged
about 2.6V, the Q401 starts to turn off
and MCU_RESET is pulled to low level.
Reset process finished.

To reset when AC is cut off, the nether
circuit works. When 12V drops to about

8.9V, Q404 turns on. Then the voltage

----Amplifier

The TAS5707 is a 20-W, efficient, digital-audio power amplifier for driving stereo bridge-tied speakers.

One serial data input allows processing of up to two discrete audio channels and seamless integration

to most digital dudio processers and MPEG decoders.

I2S, also known as Inter-IC Sound, is an electrical serial bus interface standard used for connecting

digital audio devices together.The bus consists of at least three lines: 1.Serial Clock, also named BCLK;

2.Word clock line - also called word select (WS) or left right clock (LRCLK);3.The serial data SDATA.

It may also include the Master clock (typical 256 or 384 x LRCLK).

3D TV Introduction

3DTV is television that conveys depth perception to the viewer by employing techniques.
Most modern 3D television sets use an active shutter 3D system or a polarized 3D system,
and some are autostereoscopic without the need of glasses.

The MS901K-AP series use an active shutter 3D system.

How can we see the 3D image?

1.The left eye can only see the left

The formation of 3D

image in the brain

eye image, the right eye can only
see the right eye image.

2.Right and left eyes see image with
parallax.

Right and left eyes

see image with parallax

-42-

3D TV Introduction

An active shutter 3D system is a
technique of displaying stereoscopic
3D images. It works by openly presenting
the image intended for the left eye while
blocking the right eye's view, then
presenting the right-eye image while
blocking the left eye, and repeating
this so rapidly that the interruptions
do not interfere with the perceived fusion
of the two images into a single 3D image.
The glasses are controlled by a timing
signal that allows the glasses to
alternately darken over one eye, and
then the other, in synchronization with
the refresh rate of the screen. The
timing synchronization to the video
equipment can be achieved via a
wireless signal by either an Bluetooth
transmitter.

Updating Mboot from USB Update will
erase the Device ID, MAC and HDCP
key. It may limit the internet services, and
HDMI source may not work as well. So
don’t update Mboot If not that necessary.

USB Update

----MEMC

The Upgrade method of MEMC is similar
to Mboot’s.

Just name the update file as 6m30.bin.
And select MEMC Upgrade.

MEMC chip for MS901K-AP series is 6M40]

Other operation is the same as Mboot

takes more time (about 3 minutes).
