Technical Manual 3
1. Introduction
This manual is only intended for technically trained personel!
It was designed to enable the technician to carry out repairs on board—level in case of malfunction.Attempts
of repairs going on component level or, due to missing knowledge, will cause follow up defects, will lead
automatically to lapse of any warranty claims. The manufacturer reserves the right to check units, having been
returned for repair, to that effect.
In the case you should need support via telephone, please keep ready the ident—no. and the serial—no., both
can be found on the type label, located on the rearside of the unit, close to the mains inlet.
If you will have to return a defective unit for repair, please attach a detailed fault description, including when
and how the problem appears ( e.g. always after swichting on, sporadically, etc.)
In the unlikely event a problem should be unreproducible in our workshop, we immediately would like to get in
contact with you. For this reason it is very helpful if in the delivery note, besides the fault description, also a
technical contact person (incl. telephone—no.) is mentioned.
When working at respectively inside the device, always
disconnect mains inlet!
There are dangerous voltages inside the unit. The
regulations
and safety instructions according to VDE
shall be valid as well as the respective national
deviations!
Keep to ESD regulations!

Service Hints
4. Service-Hints
4.1 Transport
The displays may only be transported in upright position! For the transport you have to take care for a save
pakking, for this the original packing, which is available at your LOEWE service (
See chapter 2. on page 3)
suits best.
4.2 Cleaning
For cleaning of the surface a dampened, lint—free cloth is most suitable. As cleaning liquid the manufacturer
recommendsenvironmental friendly glass cleaner.
Most suitable for the claening of the ventilation openings is a handheld vacuum cleaner, cleaning by means of
compressed air is not recommended, as dust might get into the unit.
4.3 Test patterns
When usingAV3 signal processing, test patterns are available under the service menu
(see also chapter 8. on
page 16)
4.4 Ground straps
Ground straps, which connect the display with the housing of the unit, must be refitted after repair, to keep to
EMI regulations. Straps, which have been torn apart when removed, have to be substituted.
4.5 OSD—Duration
ForService itishelpful, toset theduration fortheOSD to”off”.Themenues willthennot disappearautomatically
(see also Operating Manual)
4.6 Reset
On malfunction or when the device has ”stuck up” (no control via IR possible anymore), switch off unit via
mains power switch — wait for 30 sec (until all electrolyt—capacitors are discharged) — switch on unit again.

6.4 Fault finding
6.4.1 Without opening the unit
— Analysis Front LEDs
Red LED remains lit in spite of switching unit on with remote: device stays in standby, possible faults are IR
remote control or AV3..
Green LED but no picture: device is active but shows no image, possible faults are: wrong input source
selectedor panel defective.
Red and green LED is lit at the same time: unit is in an undefined state, fault caused mostly by AV3
— Analysis Screen
If with a black screen (no image is displayed) a light gleam is still visible (darken point of view with hand),
normally the problem is located in the signal routing and not on the panel itself.
.
— Accoustic Analysis (Relais)
When switching between the different input sources, there is a gentle click of a relais to be heard. If this is not
audible, the problem is certainly located on the AV3.
6.4.2 With open unit
— Check supply voltages (use the pins of the connectors for testing points,
(see chapter 6.3 on 11)
.
— Problem containment (by means of checking and / or exchange of single PCB’s)..
6.4.3 FAQs
Noisy picture in tuner mode
— Signal level must be higher than 68dbµV (typical level of cable TV)
— High noise level on RF signal (poor SNR)
— Adjust DNC to max. (OSD)
— Due to the digital signal processing flat panels are more sensitive to noise levels than 50Hz interlace CRTs
or50Hzprogressive CRTs (8Bitresolution,False Contouring, Dithering,Deinterlacing, limits ofthe used PDPs,
...)
Noisy picture in Video mode
— High noise level on Video signal (poor source)
— Adjust DNC to max. (OSD)
Technical Manual 13
—
Due to the digital signal processing flat panels are more sensitive to noise levels than 50Hz interlace CRTs or
50Hz progressive CRTs (8Bit resolution, False Contouring, Dithering,Deinterlacing, limits of the used PDPs, ...)
— If possible do not use FBAS signals, better is SCART—RGB or S—Video.
Regular horizontal or vertical stripes in Video picture
— Change position of external signal wiring (emission of PDPs)
— Humming loop (ground shift)
Video picture only in black and white
— Poor signal level or non—standard signal
— Signal not supported (e.g. NTSC via RF)
At channel search, not all channels are recognized or recognized with the wrong name
— device is not supporting PDC
— device is working with internal channel name table, if the channel name changes shortly, this may lead to
wrong information
Image is flat and low contrast (Video/VGA)
— The factory defaults for brightness and contrast are suitable for most applications, only for exceptions this
settings should be changed
— Also other settings and adjustments might influence the picture quality, for this reason always first reset to
factory
defaults (OSD—Menu)
Picture out of focus in VGA—Mode
— Max. resolution of 848x480 is recommended
— in rare cases (poor signal quality or unfavourable display), auto—adjustment is not able to work correctly
(see Operating manual), select manual adjustment in the OSD
— Adjust focus in menu Picture to the signal source

7. Startup Sequence
Description and Pinning
Startup sequence AV3 in connection with the PSU of the Plasma:
1. Step
On CN801 of the PDP PSU, Pin3, +5VDC appears.
2. Step
CN801, Pin1 (ACDET) switches to ”high”, as soon as the voltage from the PSU becomes higher than 90VAC. If the
voltage remains under 90VAC, the startup will stop here (is interrupted by the AV3).
3. Step
To start the plasma, the signal RYLON (CN801, Pin2) is set to 5V, which causes the startup of the low voltages on the
PSU, as e.g. 5V, 12V, 30V, etc.
4. Step
The signal 5VDET (CN801, Pin6) is under surveillance. If the signal is ”low”, the AV3 will setRYLON = 0V (this causes
the switch off of the panel).
5. Step
On ”high”—signal (RYLON = 5V) the AV3 will set VSON to ”high” (CN801, Pin5) and will switch also the high voltages,
the panel is under operation.

8. Service OSD
Beside the User—OSD there is an additional Service—OSD, in which settings and adjustments can be
made whichwill change the performace of the display, alternatively will show information which are helpful
for service. For this reason the access to this menu should only be familiar to suitablely educated persons.
To enter the service menu, first the user menu has to be opened (button ”menu” on your remote control),
afterwards you can enter the service menu by typing the code ”8640” on your remote control.
The following menu will appear (the values which are shown are only wildcards and will differ in most cases
from the effective values):
Here the download speed for an eventual software
update is set. If there are problems during an update. it
is recommended to reduce the speed.
In the internal memory of the AV—electronic logos of
different customers are archived. To avoid irritations,
this setting should not be changed.
This item defines the input source, which is activ when
the unit is started up. There are all input sources
available to chose from, additionally there is the
possibilityof”Last”. Ifthisis chosen,thedevice willstart
up autiomatically with the same source it has been in
when being switched off.
For service purpose (Pixelfault finding, check of Burn—
Ineffects) it ishelpful to displaya picture inRed, Green,
Blueor White.The selectedmaskis shownafter leaving
the menu. When ÒInvertedÓ is selected, the actually
displayed image will be shown in inverted colors. This
functionmight be helpfulto eraseslight Burn—In effects
(the ”Burned—In” image must be available). Items,
which are not part of the above mentioned table, can
be set via the following sub—menus:

8.1.1 Version / System Info
Sub menu Version / System Info shows the actual
software version, the hardware version and the
audio processor type (MSP).
Ther are no adjustments possible. In all service
cases, where consultation with the manufacturer
should be necessary, for this information will be
asked.
8.1.2 Operation Time
Sub menu Operation Timeshows the operation
time of the complete unit (also standby) as well as
the operation time of the panel.
Via ”Reset” both values can be reset to ”0” . This is
necessary when, e.g. the panel has been
exchanged during repair.
CAUTION:
If here the values are reset to ”0”, there
is no other possibility to assess the operating time
of the device. It is highly recommended to record
the operating time in written form in the repair form
or in different form (e.g. photograph).
8.1.3 Default Color Setting
In sub menu Default Color Setting the basic
adjustment of the colors for all input sources is set.
The offset value defines the color temperature for
the complete display, including the background, the
gain-value influences the colors of the image
content.
As a basic principle it should always be tried to do
any color adjustments via the user—menu, for
certain applications, however, it might be
necessary to do adjustments in this menu (e.g.
applications in T.V.
producing branches).
8.1.4 Temparature Setting
The AV3—electronics contains an implemented
temperature—control, which consists of three
steps
(see chapter 4.9 on page 7)
. The factory—
made values are for optimum operation of the
device and should only be changed in extreme
individual cases after consulting the manufacturer.
Any defects, caused by unauthorized changes in
the temperature control, will automatically lead to
loss of any warranty claims.
For service purpose it is possible to reset the
Max.— / and MIN.—Temperature. This allows to
check, if the unit moves towards critical
temperatures at certain applications.

the customization can be done here.
8.1.6 Reset Everything
With Reset Everything all adjustments, the channel
memory, the Max.— / Min.—Temperatures as well
as the Operating hours will be reset, which means
thedevice isin thesamestatus asoriginally delivered
by the manufacturer.
This should only be done after consulting the
manufacturer, as with the erased temperatures and
operating hours important information will be lost
which might be necessary for warranty claims.

9. Plasma Display
Following you will find the description of the Plasma Display Type PDP 42V6####.
9.1 Rear view including PCBs
If a repair exchange has to be carried out, special care has to be taken of the so called E/X Tube. Via this
sealed glass tube the panel is bleeded first, after that it becomes filled with gas. If this tube becomes broken,
the panel is totally lost.Also when changing the panel, take care of the flec cables, any damages will also lead
to a total loss of the panel, as those cables are bonded between the glass layers of the panel.
On the so called Type Labels you will find the panel type and the serial number of the panel. This information
should be noted on the delivery notes in case of repair exchange.
9.2 Schematic Configuration
Theschematicconfiguration ofthe panel shows,which PCBs belongtogether and whichsignals are conducted
to the panel. The mentioned voltages Vs, Va and Vcc are from the PSU, which is part of the panel. Any
exchange of the PSU by untrained persons is not recommended, as the voltages on the PSU have to be
adapted to the correspondingpanel.
