Cautions regarding use in high and low temperature environments
• When the unit is used in a low temperature space (e.g. room, offi ce), the
picture may leave trails or appear slightly delayed. This is not a malfunction, and the unit will recover when the temperature returns to normal.
• Do not leave the unit in a hot or cold location. Also, do not leave the
unit in a location exposed to direct sunlight or near a heater, as this may
cause the cabinet to deform and the LCD panel to malfunction. Storage
temperature: –20°C to +60°C

SAFETY NOTICE
Many electrical and mechanical parts in LCD television have special safety-related characteristics.
These characteristics are often not evident from visual inspection, nor can protection afforded by them be necessarily
increased by using replacement components rated for higher voltage, wattage, etc.
Replacement parts which have these special safety characteristics are identied in this manual; electrical components
having such features are identied by “ “.
For continued protection, replacement parts must be identical to those used in the original circuit.
The use of a substitute replacement parts which do not have the same safety characteristics as the factory recommended
replacement parts shown in this service manual, may create shock, re or other hazards.
IMPORTANT SERVICE SAFETY PRECAUTION
Service work should be performed only by qualied service technicians who are thoroughly familiar with all
safety checks and the servicing guidelines which follow:
WARNING
1. For continued safety, no modication of any circuit should be attempted.
2. Disconnect AC power before servicing.
BEFORE RETURNING THE RECEIVER (Fire & Shock Hazard)
Before returning the receiver to the user, perform the following safety checks:
1. Inspect all lead dress to make certain that leads are not pinched, and check that hardware is not lodged between the
chassis and other metal parts in the receiver.
2. Inspect all protective devices such as non-metallic control knobs, insulation materials, cabinet backs, adjustment and
compartment covers or shields, isolation resistor-capacitor networks, mechanical insulators, etc.
3. To be sure that no shock hazard exists, check for leakage current in the following manner.
• Plug the AC cord directly into a 220~240 volt AC outlet. (Do not use an isolation transformer for this test).
•Using two clip leads, connect a 1.5k ohm, 10 watt resistor paralleled by a 0.15µF capacitor in series with all exposed metal
cabinet parts and a known earth ground, such as electrical conduit or electrical ground connected to an earth ground.
•A true RMS reading multimeter should be used for this test, especially where the equipment uses a switch mode
power supply which may result in very non-sinusoidal leakage current.
•Connect the resistor connection to all exposed metal parts having a return to the chassis (antenna, metal cabinet,
screw heads, knobs and control shafts, escutcheon, etc.) and measure the AC voltage drop across the resistor.
All checks must be repeated with the AC cord plug connection reversed. (If necessary, a nonpolarized adaptor plug must
be used only for the purpose of completing these checks.)
Any reading of 1.05V peak (this corresponds to 0.7 mA. peak AC.) or more is excessive and indicates a potential shock
hazard which must be corrected before returning the monitor to the owner.

PRECAUTIONS FOR USING LEAD-FREE SOLDER
1 Using lead-free wire solder
When xing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional lead
wire solder may cause damage or accident due to cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40°C, we recommend you to
use a dedicated soldering bit, if you are not familiar with how to obtain lead-free wire solder or soldering bit, contact our
service station or service branch in your area.
2 Soldering
As the melting point of lead-free solder (Sn-Ag-Cu) is about 220°C which is higher than the conventional lead solder by
40°C, and as it has poor solder wettability, you may be apt to keep the soldering bit in contact with the PWB for extended
period of time. However, Since the land may be peeled off or the maximum heat-resistance temperature of parts may be
exceeded, remove the bit from the PWB as soon as you conrm the steady soldering condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded. Make sure to turn on and
off the power of the bit as required.
If a different type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder. Clean the bit after every
use of it.
When the tip of the soldering bit is blackened during use, le it with steel wool or ne sandpaper.
Be careful when replacing parts with polarity indication on the PWB silk.
Lead-free wire solder for servicing.

2. TUNER
FT 2112/3/8/9 are newly developed Half-NIM modules designed for both digital
(DVB-T / T2 and DTMB for terrestrial China) and analog TV reception in compliance with
the European ATV standards for analogue, as well as with the terrestrial standard ETS 300
744 for DVB-T and the new terrestrial standard ETS 302 755 for DVB-T2. It consists of a 3band RF tuner, which receives RF signal and down-converts it to an IF frequency of 36MHz
for digital and 38.9MHz for analog IF. The analogue IF output can directly drive a SAW
filter. A digital IF Stage, which consists of one SAW filter & gain-controllable IF that offers a
sufficient output level to be connected directly to an A/D converter.
In active antenna option, the following circuit are used. ANT_CTRL pin is controlled by
microcontroller. If ANT_CTRL is low, ANT_PWR will be low. If ANT_CTRL is high,
ANT_PWR will be high. OVER_CUR_DETECT pin is a monitor for short circuit in antenna.
OVER_CUR_DETECT is low, ANT_CTRL will be low, so ANT_PWR will be low. Finally,
short circuit protection is done by circuits and microcontroller.

3. AUDIO AMPLIFIER STAGES
A. MAIN AMPLIFIER (TPA3110)
a. General Description
17MB70 uses TPA 3110 15-W filter-free stereo Class-D audio power amplifier for main
audio output. The TPA3110D2 is a 15-W (per channel) efficient, Class-D audio power
amplifier for driving bridged-tied stereo speakers. Advanced EMI Suppression Technology
enables the use of inexpensive ferrite bead filters at the outputs while meeting EMC
requirements. SpeakerGuard™ speaker protection circuitry includes an adjustable power
limiter and a DC detection circuit. The adjustable power limiter allows the user to set a
"virtual" voltage rail lower than the chip supply to limit the amount of current through the
speaker. The DC detect circuit measures the frequency and amplitude of the PWM signal and
shuts off the output stage if the input capacitors are damaged or shorts exist on the inputs.
The TPA3110D2 can drive stereo speakers as low as 4 7KHKLJKHIILFLHQFy of the
TPA3110D2, 90%, eliminates the need for an external heat sink when playing music. The
outputs are also fully protected against shorts to GND, VCC, and output-to-output. The shortcircuit protection and thermal protection includes an auto-recovery feature.
