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.

voltages. Power stage which is on-chassis generates 5V, 3V3 stand by voltage and 12V,
8V, 5V, 3V3, 2.5V, 1,8V and 1,2V supplies for other different parts of the chassis. Chassis
block diagram is indicated below.
The blocks on power block diagram is using dependent to main supply. For PW26 and
PW27 just common blocks are enough for proper operation.
For IPS16, IPS17, IPS60 below blocks must work properly.
For adopter case also below blocks are necessary.
Short CCT Protection Circuit
Short circuit protection is necessary for protecting chassis and main IC against damages
when any Vcc supply shorts to ground. Protect pin should be logic high while normal
operation. When there is a short circuit protect pin shold be logic low. After any short
detection, SW forces LEDs on LED card to blink.

131,072 x 8 internally.The MX25L1005 feature a serial peripheral interface and software
protocol allowing operation on a simple 3-wire bus. The three bus signals are a clock
input (SCLK), a serial data input (SI), and a serial data output (SO). SPI access to the
device is enabled by CS# input. The MX25L1005 provide sequential read operation on
whole chip. After program/erase command is issued, auto program/ erase algorithms
which program/ erase and verify the specified page or sector/block locations will be
executed. Program command is executed on page (256 bytes) basis, and erase
command is executes on chip or sector(4K-bytes) or block(64K-bytes). To provide user
with ease of interface, a status register is included to indicate the status of the chip. The
status read command can be issued to detect completion status of a program or erase
operation via WIP bit. When the device is not in operation and CS# is high, it is put in
standby mode and draws less than 10uA DC current. The MX25L1005 utilize MXIC's
proprietary memory cell, which reliably stores memory contents even after 100,000

14. NAND FLASH MEMORY – NAND512XXA2C (U162)
14.1. General Description
The NAND flash 528-byte/ 264-word page is a family of non-volatile flash memories that
uses the single level cell (SLC) NAND technology. It is referred to as the small page
family.
The NAND512R3A2C, NAND512R4A2C, and NAND512W3A2C have a density of 512
Mbits and operate with either a 1.8 V or 3 V voltage supply. The size of a page is either
528 bytes (512 + 16 spare) or 264 words (256 + 8 spare) depending on whether the
device has a x8 or x16 bus width.
The address lines are multiplexed with the Data Input/Output signals on a multiplexed x8
or x16 input/output bus. This interface reduces the pin count and makes it possible to
migrate to other densities without changing the footprint.
To extend the lifetime of NAND flash devices it is strongly recommended to implement an
error correction code (ECC). The use of ECC correction allows to achieve up to 100,000
program/erase cycles for each block. A write protect pin is available to give a hardware
protection against program and erase operations.

25. TROUBLESHOOTING
25.1. No Backlight Problem
Problem: If TV is working, led is normal and there is no picture and backlight on the panel.
Possible couses: 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.
Backlight power supply should be in panel specs. Please check CN705 for MB60, related
connectors for power supply cards.
STBY_ON/OFF should be low for standby on condition, please check R1677.
25.2. CI Module Problem
Problem: CI is not working when CI module inserted.
Possible couses: Supply, suply control pin, detect pins, mechanical positions of pins
CI supply shoul be 5V when CI module inserted. If it is not 5V please check
CI_POWER_CTRL, this pin should be low.
Please check mechanical positions of CI module.
Detect ports should be low. If it is not low please check CI connector pins, CI module pins
and 3V3_VCC on MB60.
25.3. Led Blinking Problem
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.
25.4. IR Problem
Problem: LED or IR not working
Check LED card supply on MB60 chasis.
25.5. Keypad Touchpad Problems
Problem: Keypad or Touchpad is not working
Check keypad supply and KEYBOARD pin on MB60.
25.6. USB Problems
Problem: USB is not working or no USB Detection.
Check USB Supply, It should be nearly 5V. Also USB Enable should be logic high.
25.7. No Sound Problem
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.
25.8. No Sound Problem at Headphone
Problem: No audio at headphone output.
Check HP detect pin, when headphone is. Check 5V_VCC and 3V3_VCC with a voltagemeter.
25.9. Standby On/Off Problem
Problem:
Device cannot boot, TV hangs in standby mode.
There may be a problem about power supply. Check 12V_VCC, 5V_VCC and 3V3_VCC
with a voltage-meter. Also there may be a problem about SW. Try to update TV with latest
SW. Additionally it is goood to check SW printouts via hyper-terminal (or Teraterm).
These printouts may give a clue about the problem.
DVD Problems
Problem: DVD is not working.
Check that DVD source is selected in Service menu. Check supply voltage of DVD
namely 12V_VCC.
25.10.
No Signal Problem
