II. Image and Sound Process
UOC chip receives the IF signal separated from SAW, detect and decode. Output RGB
color analog signals from the 85、86、87 pin respectively. Output the main channel L、R audio
signal from 60、61 pin. Output earphone channel L、R audio signal from 62、63 pin. additional,
Part number U7,TDA9178 complete the enhancement of quality of the picture ,by the output
74、75、76 pin Of UOC and the input 70、71、72 pin, combined with UOC to form a loop circuit.
Further, AV、S-Video、YC signal of inside DVD(some types of TV have not) is also decoded
inside of UOC chip, switch internal UOC with TV input and output a RGB color analog signal,
send it to back-end process.
III. Digital Signal Processes
The analog RGB signal output from UOC and RGB signal output from DFP are switched
and selected by a PI5V330A; input it into the 65、63、60 pin Of MST518. The RGB signal output
from computer and HD-YpbPr signal are switched and selected by another PI5V330A,input
into the 75、72、70？of MST518.This two channel RGB signal are switched inside
MST518,then AD converter, video format transition, at last output digital color signal which is
suitable for TFT drive circuit. MST518 process the pixels ratio converting of input video signal、
the image auto optimization process, then process memory buffer、scaler、chroma matrix
circuit、chroma look-up table、chroma space gain, etc. Output corresponding standard physical
resolution digital color signal and corresponding sync, clock signal to TFT, control the TFT to
display image correctly.

turning on the TV,
poor light is bright.
No picture, no sound,
no snowflake in TV
condition, but AV is
normal.
LCD TV can not be
controlled (inc red
lamp is no but the TV
is off, remote control
and key press in TV
can not control the
TV, etc.)
If some display board of DVI can not receive the data
when turning on the TV, there is no output; if pull out
the DVI line abruptly, there is also no DVI output;
Before starting PC, connect the DVI line with LCD TV
steadily. So DVI can receive the correct date from
DDC (Display Data Channel) when turning on the TV,
DDC is in chassis 24LC21.
Check the connect line in up screen, and connect the
line.
Check the outside of RF (also bus and power
supply), there is no problem but no output from RF,
so the RF is disabled.
The LCD TV can not work abruptly, power off and
turning it on again.

WALL-MOUNTING BRACKET INSTALLATION GUIDE
READ CAREFULLY BEFORE INSTALLATION!
THE INSTALLATION GUIDE SHOULD BE RETAINED FOR FUTURE REFERENCE.
Caution:
1. DO NOT attempt to install the TV by yourself to avoid mistakes or hazard. Refer all installation to qualified servicing personnel.
2. DO NOT install the TV on a wall aslope or a wall that makes the TV screen sloping over 25º off plumb line. Otherwise, it may cause tumble or injury.
3. One must follow the instructions in this guide to correctly install the TV.
4. It requires more than one person to install the TV.
5. Before installation, examine whether the wall conforms to the specifications and whether the supplied parts can be fixed on it. The wall for mounting should
sustain the weight of TV and speakers e.g. cement wall or brick wall. DO NOT attempt to install an area with standard building rigidity, which sustains the
weight of the TV and speakers. If the rigidity of the wall can not be measured, every mounting hole should sustain a frontal force over 75N, and a shearing
force of over 150N.
6. Use the specified electric drill and drill bit for drilling. The drilling holes should conform to the specifications.
7. To avoid fire and shock, do NOT place radiator, heater or humidifier below the installed TV.
8. The TV should be kept away from moisture, sensors and power line. The TV should be kept away from impact and vibration.
9. Ensure that the power supply be disconnected before installation for fear of fire and shock.
Wall-mounting Installation Steps:
1. Take out the bracket form the package and check if there are serious defects (e.g. infirm juncture).
2. Adjust the bracket to the desired angle. Use bolt 7 to adjust the angle by meeting holes of column beam2 and holes of lever 4.
3. Drill locating holes in the specified dimension in a vertical wall of concrete or brick. The hole size should be 11mm. The hole depth should accommodate
the expanding tube of the bolt.
4. Fix the bolts into the drilled holes in step3, and then cover each bolt with a metal washer. Meet the four mounting holes in the bracket with the four bolts in
the wall, cover each bolt with a metal washer, and then fasten with a screw nut. Check its rigidity by pulling the bracket.
5. Fix the fixture disk to the back cover of the TV using six M4x20 bolts.
6. Wall-mount the TV by putting the six-fixture disk into the six mounting holes A.
