12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold
with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination
to avoid injury from tip-over.
13. Unplug this apparatus during lightning storms or when unused for long periods of time.
14. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has
been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled
or objects have fallen into the apparatus, the apparatus has exposed to rain or moisture, does
not operate normally, or has been dropped.
16. WARNING - To Reduce The Risk Of Fire Or Electric Shock, Do Not Expose This Appliance To Rain Or
Moisture.
17. Wet Location Marking : Apparatus shall not be exposed to dripping or splashing and no objects
filled with liquids, such as vases, shall be placed on the apparatus.
POWER CAUTION
Most appliances recommend they be placed upon a dedicated circuit; that is, a single outlet circuit
which powers only that appliance and has no additional outlets or branch circuits. Check the specification
page of this owner’s manual to be certain. Do not overload wall outlets. Overloaded wall outlets,
loose or damaged wall outlets, extension cords, frayed power cords, or damaged or cracked wire
insulation are dangerous. Any of these conditions could result in electric shock or fire. Periodically
examine the cord of your appliance, and if its appearance indicates damage or deterioration, unplug
it, discontinue use of the appliance, and have the cord replaced with an exact replacement part by an
authorized servicer.

SAFETY
Protect the power cord from physical or mechanical abuse, such as being twisted, kinked, pinched,
closed in a door, or walked upon. Pay particular attention to plugs, wall outlets, and the point where
the cord exits the appliance.
ELECTRICAL SAFETY NOTICE
Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified
in the Schematic Diagram and Replacement Parts List. It is essential that these special safety parts should be replaced
with the same components as recommended in this manual to prevent , Shock, Fire, or other Hazards. Do not modify the
original design without permission of manufacturer.
ELECTRICAL SHOCK WARNING
An lsolation Transformer should always be used during the servicing of a receiver whose chassis is not isolated from the
AC power line. Use a transformer of adequate power rating as this protects the technician from accidents resulting in
personal injury from electrical shocks. It will also protect the receiver and its components from being damaged by
accidental shorts of the circuit that may be inadvertently introduced during the service operation. If any fuse (or
Fusible Resistor) in this monitor is blown, replace it with the same specified type. When replacing a high wattage
resistor (Oxide Metal Film Resistor, over 1W), keep the resistor 10mm away from PCB. Keep wires away from high voltage
or high temperature parts.
LEAKAGE CURRENT COLD CHECK (ANTENNA COLD CHECK)
With the instrument AC plug removed from AC source, connect an electrical jumper across the two AC plug prongs.
Place the AC switch in the on positioin, connect one lead of ohm-meter to the AC plug prongs tied together and
touch other ohm-meter lead in turn to each exposed metallic parts such as antenna terminals, phone jacks, etc. If
the exposed metallic part has a return path to the chassis, the measured resistance should be between 1M ohm and
5.2M ohm. When the exposed metal has no return path to the chassis the reading must be infinite. An other
abnormality exists that must be corrected before the receiver is returned to the customer.
LEAKAGE CURRENT HOT CHECK
Plug the AC cord directly into the AC outlet. Do not use a line Isolation Transformer during this check. Connect
1.5K/10watt resistor in parallel with a 0.15uF capacitor between a known good earth ground (Water Pipe, Conduit,
etc.) and the exposed metallic parts. Measure the AC voltage across the resistor using AC voltmeter with 1000 ohms/
volt or more sensitivity. Reverse plug the AC cord into the AC outlet and repeat AC voltage measurements for each
exposed metallic part. Any voltage measured must not exceed 0.75 volt RMS which corresponds to 0.5mA. In case
any measurement is out of the limits sepcified, there is possibility of shock hazard and the set must be checked and
repaired before it is returned to the customer.

GROUNDING
Ensure that you connect the earth ground wire to prevent possible electric shock. If grounding
methods are not possible, have a qualified electrician install a separate circuit breaker. Do not try to
ground the unit by connecting it to telephone wires, lightening rods, or gas pipes.
PLACEMENT
The TV can be installed in various ways such as on a wall, or
on a desktop etc. Some models can be mounted verically
(Portrait) or horizontally (Landscape). Do not mount models
that are not denoted as pivot models veritcally. For proper
ventilation, allow a clearance of 4 in. on each side and the
top, 2.36 in. on the bottom, and 4 in. from the wall.

OPERATION
MANUAL PICTURE CONTROL
The Manual Picture Control option allows users to set individual picture controls such as Contrast,
Brightness, Color, Tint, Sharpness, and Color Temperature. The Manual Picture Controls should be
used to properly set the display once it is in a users home. The environment around the display will
affect the perceived quality of the display. For example, the color of the walls and flooring will
affect the color levels seen on the display. Also, the amount of ambient light in the room will affect
the brightness of the display.
To properly set the Manual Picture Control levels:
1. Make sure the display is in its final place in the room. (If the display is moved to another
position, the controls will need to be re-adjusted.)
2. Adjust ambient light. The adjustments should be made for night time movie watching as,
this is when consumers are most critical of picture quality. The room should be darkened
with little to no ambient light in front of the display. For best results, and to reduce the
chance of eye strain, there should be slight ambient light behind the display.
3. Turn off or disable any additional video signal processing such as: XD Engine, Velocity
Scan, etc
4. Set EZ Picture to the Normal setting.
5. Set Color Temperature to the Warm setting.
Contrast – The Contrast control is used to adjust the White Level of the display. The proper setting
for contrast is only high enough to allow the difference between white and light gray to be seen.
When contrast is set too high, light grays will appear washed out or white, and whites can begin to
bloom or over saturate with color (appear slightly blue, pink, or green). When contrast is set too
low, whites will appear gray.
To properly set the Contrast Level, lower the contrast setting so that white becomes gray. Next,
begin stepping up the contrast level until the lightest gray color becomes white (white and gray
sections become one larger section) and then move the control down one step. There should always
be a noticeable difference between white and light gray and also note that for best results on all
display types (and to reduce display wear) the Contrast Level should be no higher than “85”.
Brightness – The Brightness control is used to adjust the Black Level of the display. The proper
setting for brightness is only high enough to allow the difference between black and dark gray to be
seen. When brightness is set too high, blacks will appear washed out or gray. When brightness is set
too low, dark grays will appear black.
To properly set the Brightness Level, begin stepping down the brightness level until the darkest
gray disappears into black (at the same time, black and “blacker-than-black” will mix into one.
Next, step the brightness level up once so that, black and “blacker-than-black” remain together yet
the darkest gray is visible.
NOTE: The Brightness and Contrast controls interact with each other. The current brightness
setting will affect the white level and the current contrast setting will affect the black
level. Therefore, you may need to readjust the contrast setting after adjusting the
brightness setting, and likewise readjust the brightness setting after subsequent contrast
settings. Keep repeating the adjustment until the black and white levels are reached.
Color – The Color control is used to adjust the Color Saturation of the display. The proper setting
for color is to the point where the primary (red, green, & blue) and sub-primary (yellow, cyan, &
magenta) colors appear as their pure, natural colors without “bleeding” into other colors. When
Plasma Training 19 Operation
Page 20
OPERATION
color is set too high, predominant colors, such as red, will bloom and bleed, causing white to
appear pink, and yellow to appear orange. When color is set too low, the entire image will appear
more gray than colored, with the extreme lower limit resulting in a Black & White picture. To
properly set the Color Level, lower the color setting to the point where colors begin to appear gray.
Next, begin stepping up the color level until the primary and sub-primary colors begin to exceed
their normal color representations.
Tint – The Tint control is used adjust the Hue of the display between red or green. The proper
setting for tint is, as with the color setting, to the point where the primary (red, green, & blue)
and sub-primary (yellow, cyan, & magenta) colors appear as their pure, natural colors without
bleeding into other colors. The extreme settings of tint will result in a red/magenta overall hue or
a green/cyan overall hue. To properly set the Tint control, adjust towards red if yellows appear with
a green tint or towards green is yellows appear with a red or orange tint.
NOTE: The Color and Tint controls interact with each other. The current color setting will affect
the hue and the current tint setting will affect the saturation. Therefore, you may need
to readjust the color setting after adjusting the tint setting, and likewise readjust the tint
setting after subsequent color settings. Keep repeating the adjustment until the best
color representation is reached.
TIP: After Color and Tint adjustments are completed, reds may over saturate slightly, causing
yellows to appear orange. You may need to slightly reduce the color level to compensate
for this effect.
Sharpness – The Sharpness control is used to adjust the amount of data added to the display
image. When the sharpness control is set too high, white or jagged edges will appear on black lines
or the edges of objects. When the sharpness control is set too low, the edges of objects or black
lines will appear fuzzy. To properly set the Sharpness control, adjust the setting up or down until
black lines have crisp, clean edges, while maintaining the overall brightness level across the image.
TIP: If a noticeable difference is not seen during the sharpness adjustment, simply place the
control at the 50 mark.

The Warm setting will provide a slightly red tint to the picture. Once the previous adjustments have
been made, the color temperature may be changed for personal preference.

DIGITAL PCB
The digital board below is from the 60PY2DR, other models may differ slightly.
The digital PCB provides Digital Signal Processing (dsp) and controls the state of each FET on each
DRIVER B/D with R, G, B, each with 8bit input. This board contains the Cablecard slot and supporting
buffers which are shared with the Cablecard while it is in operation due to the data flow from the
cable headend to the card. This data flow constantly updates the channel list and the CP (Copy
Protect) data and the channel authorization list and the encription and descramble data. This is done
every ten to twenty seconds. This PCB also is host to the HDD (Hard Disk Drive) control circuit. This
circuit will recognize the HDD if it is programmed and formated correctly. These drives are setup
especially for this function, thus a drive from another vender will not function in this unit. This is
done for CP (Copy Protect) reasons. If the HDD is suspect of errors or video issues, power down the
unit and remove A/C and disconnect the IDE cable and power the unit back on. If the problem still
exists, the problem is not on the HDD. The unit can be used without the HDD connected. In this
situation the unit will function normally except any function related to the HDD or demo mode which
is stored on the HDD. This PCB also contains all of the Digital inputs. The analog to digital conversion
is done on this PCB as well.

TUNER PCB
TUNERS
JACK PACK
CABLE INPUT
A tuner is a device to adjust the resonant frequency of an antenna or transmission line to work most
efficiently at one frequency or band of frequencies. Most tuners do all the low level demodulation
needed to convert a radio signal into an on-screen image using a hardware DSP chip or ASIC; some
also have hardware MPEG decoders. This PCB contains three tuners, one OOB (Out Of Band), one
digital tuner, and an analog tuner.
NOTE: The RCA cables connecting the tuner to the RF adapter do NOT come with PCB replacements.
They must be removed from the original PCB and connected properly to deliver the correct
signal to the correct tuner.
NOTE: The ribbon cables seen in the upper left connect this PCB to the Digital PCB and will tear or
crease easily. A tear or crease can easily lead to a misdiagnosis. If these cables become creased
or damaged in any way. Test them with an ohm meter to check each conductor for continuity.

During normal operation the Vsc at this testpoint is +75Vdc and -Vy is -84Vdc. These adjustments are
crucial to the panel performance. The effects you will get when _Vy is too high is minimal on a still
image. When this is set too low you will see after image and speckeling in the image due to lack of
elminating the previous displayed image. This occurs at around -125Vdc.
When Vsc is too low the brilliance of the image is not as strong due to lack of drive voltage, this is
hard to see with the naked eye. When Vsc is too high the panel begins to over drive and will reduce
the life of the panel.

SIGNAL CONTROL
Signal processing (Contour noise, reduction) controls the state of each FET on each DRIVER B/D with
R, G, B each with 8bit input (Uses 3.3V/5V 2 kinds of power ). This PCB controls all aspects of the
PDP panel. This PCB also digitally segments the panel and controls the pixels and cells as if the panel
was a large memory IC and changes the data as needed after screen by screen comparison. The data
that differs from one frame to another are the addresses that are reset and changed. The software in
this PCB differs greatly from the software in the Digital PCB.

COF is Chip On Film. If any of the tests indicate the junction is shorted or leaking, the adjacent COF
IC is defective. As a result the PDP panel will have to be replaced. Each resistor is a 10.2 - 10.8 ohm
resistor.

Why the electric discharge happens when it is not supposed to.
Wavelength above shows V_setup /V_set down that created wall charges inside panel. The wall charges that
are created by
“setup/down” wavelength, has an important role for address electric discharge.
• If Vs is less than the value on the panel label.
• The slope of “set down” period descends
• The amount of wall charge decreases.
• The picture gets darker and set turns off eventually
• If VS is greater than the value of panel label.
• The slope of set down will shorten.
• Amount of wall charge increases
• Picture gets brighter because it can’t display gray scale.
Therefore, incorrect electric discharge occurs.

CABLECARD S-CARD
CABLECARD
DIGITAL CABLE READY (DCR)
A “plug-and-play” DTV is a television that you can plug directly into your cable system and receive
analog and most digital cable services without the need for a set-top box. The cable and consumer
electronics industries have dubbed these types of televisions “digital cable ready” or “DCR.”
Digital plug-and-play will not work quite like analog. For digital plug-and-play, you’ll probably need
to get a security card (also known as a CableCARDTM) from your local cable operator. The security card
will permit you to watch scrambled programming and premium services, to which you’re subscribed.
A CableCARD device is A PCMCIA card distributed by cable operators and inserted into a DCR TV(Host)
to enable premium services, also called “Card” and “Point of Deployment(POD) module”. It provides
authorization, CA (Conditional Access) decryption and CP (Copy Protection) encryption functions for
the consumer’s DCR TV.

The OOB (Out Of Band) tuner runs all the time, locked to the frequency which it is given by the
Cablecard. The data from the Headend should be on this frequency. If it is not, the tuner wil not see
the data nor will the Cablecard. EX: If the cablecard tells the unit to tune to 104.20Mhz. The unit will
tune to 104.20Mhz and not search for other frequencies. If the MSO (Multi System Operator) has the
cards prgrammed to give the unit a list of frequencies, the unit will search that list of frequencies to
find the data and then lock. If the data is on 104.25Mhz, neither the unit nor card can get the data
needed to receive a channel list and an authorization list , the CP and decrypt data. As a result, the
unit will not be allowed to tune premium channels.
HOST-CABLECARD INTERFACE
The data communication to and from the Cablecard and unit is encrypted. The Host (Unit) and POD
(Cablecard) share a buffer so that the data from the headend is never lost. Some of the buffer is in
the POD and some is in the host.The authorization list, CP data, Decrypt data and some other data is
updated every 10 -20 seconds. This allows the cable company to add, remove, and rearrange channels
as needed and the Cablecard is updated within seconds without the customer having to run EZ Scan
to load new channels added to their lineup. The data from the headend is at regular intervals and can
fluctuate in timing. This causes the data to flow at a higher rate at times and a lower rate at other
times depending on other tasks the headend is performing on the system. The comunication between
the POD and host is a two way relationship. While the communication between the Cablecard and
headed is only one way, from the headend to the card.

Most but not all, CADTV (Cable Digital Television) channels are scrambled and or encrypted. Therefore
decryption is a part of a premium package the customer pays for. There are a few channels the cable
company has to provide as open channels. This allows the customer who purchases an HD ready TV
that is capable of processing QAM to recieve a few HD channels thru the cable system. In LG units
there are two ways the channels are displayed, as 2 part channels (EX: 107-1) and as single part
channels EX: 107. With the Cablecard inserted the CADTV map will show only single part channels.
Without the card installed the CADTV map will show two part channels. Due to this it will be in the
ASC’s best intrest to have a constantly updated channel lineup showing which are scrambled and
which are open channels for all the headends in the area you service product. A good relationship
with the local cable company is crucial to this so you are kept up to date with fast changing channel
lineups. This can prevent you from trying to repair a product that is not defective. EX: The customer
complains they no longer recieve CH 186 which was Discovery HD a scrambled channel. The real cause
is the headend moved that channel to CH 205 and CH 186 is no longer in the channel map. All this
occurs through the OOB channel.

CABLECARD AUTHORIZATION & VALIDATION PROCESSES
• In order to activate CA service (called low-value service) and to receive Cable channel map,
“Authorization process” is needed.
* Serial number and CableCARD ID are needed.
* During this process, CableCARD reset may occur.
* After this process is finished successfully, user can navigate cable channel map & can watch
CA Encrypted services to which the user subscribes.
• In order to activate additional CP services (called high-value service), a “Validation process” is
needed.
* Host/CableCARD ID is needed.
* HeadEnd sends Validation message through OOB channel.
* After Validation message is received by the CableCARD, the user can watch CP Encrypted
services also.
