Sharp LC-32LE140E LCD TV – 17MB62 chassis – Troubleshooting - Service mode - Software update
LC-32LE140E, LC-32LE140EV, LC-32LE140EK, LC-32LE140RU
TUNER(TU3)
A horizontal mounted and Digital Half-Nim tuner is used in the product, which covers 3 Bands(From 48MHz to 862MHz for COFDM, from 45.25MHz to 863.25MHz for CCIR CH).
The tuning is available through the digitally controlled I2C bus (PLL). Below you will find info about the tuner.
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 micro-controller.

General description of Sony RE216
The SUT-RE216 is designed for terrestrial TV (digital & analog) and digital cable reception. It includes a full band tuner and a channel filtering for digital signals. It provides a low IF output after channel filtering to drive a channel demodulator. Tuning, band switching and initialization are made via an I2C bus interface. The module is built on a low-loss printed circuit board carrying all the components in a metal housing frame with top and rear covers. The single aerial connector is mounted on one frame side and all other connections are made via pins at the bottom.

AUDIO AMPLIFIER STAGE WITH AZAD2102(U163, U164)
17MB62 uses two 2,5W Class D Mono Audio Amplifers for from 16” to 24” TVs.
AZAD2102B is a 2.9 Watts (max. can offer 3.0 Watts @ Load = 3Ω,THD=10%,AVdd=DVdd=5.5Volt)with high efficiency filter-free class-D audio power amplifier in a 1613 mm x 1613 mm wafer chip scale package (WCSP). AZAD2102B uses Current switch technology to achieve high performance class-d amplifier that features 0.03% THD, 85% efficiency, –70 dB PSRR, to improve RF-rectification immunity.
AZAD2102B provide a Vibration-Spectrum modulation clock for PWM Output. This vibration frequency is around 10KHZ shift (+/- 5KHZ of Fpwm).
The advantage of the small size package (WCSP) makes AZAD2102B very
suitable for mobile phone and PDA device application. And the Class-D amplifier
structure let AZAD2102B to have highly efficiency power consumption than
Class-AB amplifier. AZAD2102B can shrink
the application board, reduce system cost, and external components.

Audio amplifier stage with TPA3113(U168)
17MB62 uses a 6W Class D Mono Audio Amplifers for from 26” to 32” TVs. The TPA3113D2 is a 6-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 TPA3113D2 can drive stereo speakers as low as 4 Ω. The high efficiency of the TPA3113D2, 87%, 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 short-circuit protection and thermal protection includes an auto-recovery feature.

POWER
STAGE
The DC voltages required at various parts of the chassis and panel are provided by a main power supply unit. MB62 chassis can operate with IPS60, IPS16, IPS17, PW26, PW27 as main power supply and also with 12V adaptor. CN706 is used for IPS60, IPS16 and IPS17 and CN1 is used for PW26 and PW27 JK9 is used for the adapter option and also CN75 inverter socket or DB32 chassis with CN709 is used to supply backlight.

The
power supplies generate 18,12,5,3.3 and 12,5 volsts standy mode DC
voltages. Power stage which in ON
Chassis generates 5,3.3 standby voltes and 12,8,5,3.3,2.5,1.8 and 1.2 volts
supplies for other different parts of the chassis.
No Backlight Problem
If TV is working, led is normal and there is no picture and backlight on the panel. Possible causes: Backlight pin, dimming pin, backlight supply, stby on/off pin Backlight pin should be high in open position. If it is low, please check Q181 and panel cables.
Dimming pin should be high or square wave in open position. If it is low, please check S16 for Mstar side and panel or power cables, connectors.
Back-light power supply should be in panel specs. Check CN705 for MB62, related connectors
for power supply cards.
Led
Blinking Problem
LED blinking, no other operation
This problem indicates a short on Vcc voltages. Protect pin should be logic high while normal operation. When there is a short circuit protect pin will be logic low. If you detect logic low on protect pin, unplug the TV set and control voltage points with a multimeter to
find the shorted voltage to ground.

No
Sound Problem
No audio at main TV speaker outputs.
Check supply voltages of VDD_AUDIO, 5V_VCC and 3V3_VCC with a voltage-meter. There may be a problem in headphone connector or headphone detect circuit (when headphone is connected, speakers are automatically muted). Measure voltage at HP_DETECT pin, it should be 3.3v.

What is 3D Display?
• A system that display 3D images artifcially
• How ? Using binocular time delay
1. Left eye recognizes left image, right eye recognizes right image.
2. Human eyes be far away each other 65mm horizontally.
So each eye feels a little bit of time delay of left and right information. Human brain merges those images and can feel three-dimensional.
