PRECAUTIONS DURING SERVICING
1. In a ddition to safety, other parts and assemblies are
speci fied for conformance with such regulations as
those applyi ng to spurious radiation. These must
also be replaced only with specified replacements.
Exampl es: RF converters, tuner units, antenna
selection switches, RF cables, noise-blocking
capacitors, noise-bl ocking filters, etc.
2. Use sp ecified internal Wiring. Note especially:
1) Wires covered with PVC tubing

W ARNING:
Before servicing this TV receiver, read the X-RAY
RADIATION PRECAUTION, SAFETY INSTRUCTION
and PRODUCT SAFETY NOTICE.
X-RA Y RADIATION PRECAUTION
1. Excessively high can prod uce potentially hazardous
X-RAY RADIATION. T o avoid such hazards, the high
volta ge must not exceed the specified limit. The
normal va lue of the high voltage of this TV receiver
is 2 7 KV at zero bean current (minimum brightness).
The high voltage must not exceed 30 KV under any
circu mstances. Each time when a re ceiver requires
servici ng, the high voltage should be checked. The
readi ng of the high voltage is re commended to be
reco rded as a part of the service record, It is
important to u se an accurate and reliable high
voltage meter.
2. The only source of X-RAY RADIATION in this TV
receiver is the picture tube. For con tinued X-RAY
RADIATION protectio n, the replacement tube must be
exactly the sa me type as specified in th e parts list.
3. Some parts in this TV receiver have special safety
related characteristics fo r X-RADIATION protection.
For continued safety, the parts replacement should
be under taken only afte r referring the PRODUCT
SAFETY NOTICE.
SAFETY IN STRUCTION
The se rvice should not be attempted by anyone
unfamiliar with the ne cessary instructions on this TV
receiver. The fo llowing are the necessary instructions
to be ob served before servicing.
1. An isolation transformer shoul d be connected in the
power li ne between the receiver and the AC line
when a service is performed on the primary of the
conve rter transformer of the set.
2. Comply wi th all caution and safety related provided
on th e back of the cabinet, inside the cabinet, on the
chassis or p icture tube.
3. T o avoid a shock hazard, always discharge the
pictu re tube's anode to the chassis g round before
removi ng the anode cap.
-2-
Page 3
4. Completely discharge the high potential voltage of the
picture tube before handli ng. The picture tube is a
vacuum and if bro ken, the glass will explode.
5. When rep lacing a MAIN PCB in the cabinet, always
be certai n that all protective are installed properly
such as control knobs, adjustment co vers or shields,
barri ers, isolation resistor networks etc.
6. When se rvicing is required, observe the original lead
dressing. Extra precau tion should be given to assure
correct lead dressing in the high voltage area.
7. Keep wires away from high voltage or high te mpera
ture components.
8. Befo re returning the set to the customer, al ways
perform an AC leaka ge current check on the exposed
meta llic parts of the cabinet, such as anten nas,
termin als, screwheads, metal overlay, control shafts,
etc., to be sure the set is safe to operate without
danger of electrica l shock. Plug the AC line cord
directly to the AC outlet (do not use a line isolation
transformer d uring this check). Use an AC voltmeter
havin g 5K ohms volt sensitivity or more in the
following manner.
Conne ct a 1.5K ohm 10 watt resistor paralleled by a
0.15µF AC type capacitor, between a good earth
ground (water pipe, conductor etc.,) and the exposed
metallic parts, one at a time.
Measure the AC vol tage across the combination of
the 1 .5K ohm resistor and 0.15 uF capacitor. Reverse
the AC p lug at the AC outlet and repeat the AC
volta ge measurements for each exposed metallic
part.
The me asured voltage must not exceed 0.3V RMS.
This correspo nds to 0.5mA AC. Any value exceeding
this limit constitutes a potential shock hazard and
must be corrected immediately.
The resistance measurement should be done
betwe en accessible exposed metal parts and power
cord plug prongs with the power switch "ON". The
resi stance should be more than 6M ohms.

PCB failure analysis
1. CONTROL:
a. Abnormal noise on screen.
b. No picture.
2. MAIN (VIDEO):
a. Lacking color, Bad color scale.
b. No voice.
c. No picture but with signals output, OSD and back light.
d. Abnormal noise on screen.
3. POWER:
No picture, no power output.
Basic operation of LCD-TV
1. After turning on power switch, power board sends 5Vst-by Volt to Micro
Processor IC waiting for ON signals from Key Switch or Remote Receiver.
2. When the ON signal from Key Switch or Remote Receiver is detected, Micro
Processor will send ON Control signals to Power. Then Power sends (5Vsc,
12Vsc, 24V and RLY ON, Vs ON) to PCBs working. This time VIF will send
signals to display back light, OSD on the panel and start to search available
signal sources. If the audio signals input, them will be amplified by Audio AMP
and transmitted to Speakers.
3. If some abnormal signals are detected (for example: over volts, over current,
over temperature and under volts), the system will be shut down by Power off.

LCD basic display theory.
When an electrical field is applied to the LC planes, the LC molecules re-align
themselves so that they are parallel to the electrical field. This electrical process
is known as twisted nematic field effect or TNFE. In this alignment, polarized
light is not twisted as it passes through the LC material (see Diagram 3A and
3B). If the front polarizer is oriented perpendicular to the rear polarizer, light will
pass through the energized display but will be blocked by the rear polarizer. An
LCD in this form is acting as a light shutter.
Displays with variable characters are created by selectively etching away the
conductive surface that was originally deposited on the glass. Etched areas
become the display’s background; unetched areas become the display’s
characters.
Diagram 3A. The “off” state of a TN LCD-the LC molecules form a twist and therefore
cause polarized light to twist as it passes through.
Diagram 3B. The “on” state-the electrical field re-aligns the LC molecules so they do
not twist the polarized light.

GENERAL DESCRIPTION
The MX29L V160BT/BB is a 16-mega bit Flash memo ry
organized as 2M bytes of 8 bits or 1M words of 16 bits.
MXIC's Flash memories offer the most cost-effective
and reliable read/write non-volatile random access
memory. The MX29LV160BT/BB is packaged in 44-pin
SOP, 48-pin TSOP and 48-ball CSP. It is designed to be
reprogrammed and erased in system or in standard
EPROM programmers.
The standard MX29LV160BT/BB o ff ers access time as
fast as 70ns, allowing operation of high-speed microprocessors without wait states. To eliminate bus contention, the MX29LV160BT/BB has separate chip enable
(CE) and output enable (OE) controls.
MXIC's Flash memories augment EPROM functionality
with in-circuit electrical erasure and progr amming. The
MX29LV160BT/BB uses a command register to manage this functionality. The command register allows f or
P/N:PM1041REV. 1.2, JUL. 01, 2004
100% TTL level control inputs and fixed power supply
levels during erase and programming, while maintaining
maximum EPROM compatibility.
MXIC Flash technology reliably stores memory contents
ev en after 100,000 erase and program cycles . The MXIC
cell is designed to optimize the erase and programming
mechanisms. In addition, the combination of advanced
tunnel oxide processing and low internal electric fields
for erase and program operations produces reliable cycling. The MX29LV160BT/BB uses a 2.7V~3.6V VCC
supply to perform the High Reliability Erase and auto
Program/Erase algorithms.
The highest degree of latch-up protection is achieved
with MXIC's proprietary non-epi process. Latch-up protection is proved for stresses up to 100 milliamps on
address and data pin from -1V to VCC + 1V.
