Using the Service Center repair guide (SCRG)
The SCRG is primary dealing with fault located in the Plasma Display Panel.
Faults that occur due to setting, link failure or other faults on external connected
equipment, can not be expected to be described.
The Service Center repair guide will explain and guide you through repair of the
product.
Symbols and illustrations
A survey of symbols are available.
Symbols are used to guide in following situations:
- User action shown in an illustration
- Reference to an illustration
The symbol  is used to refer to a specic illustration.
See 2, refers to illustration 2.
Illustrations are placed in the guide so that you can read an instruction and look at
the illustrations at the same time.
Survey of symbols
Make a shortcircuit between the marked points, usually for discharging e.g. a
picture tube
Push with nger, in arrow direction
Disconnect internal plug
Connect internal plug
Disconnect mains plug

How to service
Servicing
The PDP may only be serviced by qualied technical personal.
If it is not possible to determine the location of the fault or replacing spare part
does not clear the fault, please contact your national Service Center for technical
support.
Handling
The PDP must always be placed vertical to avoid damaging it self.
There is a major risk on damaging the PDP if it is placed in a horizontal position.
Whenever possible place the PDP in the servicestand.
Clean the product
Never use alcohol or other solvents to clean any part of the product!
Use white gloves to avoid smudging the contrast screen.
Wipe dust off the surfaces using a dry, soft cloth or a micro bre cloth. Remove
grease stains or persistent dirt with a soft, lint-free, rmly wrung cloth, dipped in a
solution of water containing only a few drops of mild detergent, such as washing-up
liquid.
To retain the optimum performance of the screen, make sure that no streaks or
traces of the cleaning uid are left on the screen.
Burn-in
Burn-in on the PDP might occur when displaying a non-moving picture for more
than app. 30 minutes.
Warning
Static electricity
Static electricity may damage the product.
Static-protective eld service kit.
A static-protective eld service kit must always be used when the product is
disassembled or modules are being handled.
Follow the instructions in the guide and use the ESD-mat for both old and new
modules.
Please note:
When mains voltage on the television is required, remove the connection between
the PDP and the ESD-mat.
The chassis or modules must always be connected to the static-protective eld
service kit or placed in an ESD-proof bag.
Symbol of safety components
When replacing components with this symbol, the same type has to be used, also
the same values for ohm and watt.
The new component is to be mounted in the same way as the replaced one.
STATIC ELECTRICITY
MAY DESTROY THE
PRODUCT
ESD

1.4 How to service, English
Trouble shooting
Actions before dismantling the PDP
Check the PDP for burn-in and pixel errors!
This check is very important when the PDP must be transported to a workshop.
Refer to PDP pixel test, page 1.9.
Before dismantling the PDP - disconnect the mains supply and wait minimum
1 minute for the electolytic capasitors to discharge.
Connect ESD-mat.
Test and adjustment of module(s)
Preparations before adjustment
- Do not connect ESD-mat to PDP.
- Set the PDP to receive a picture, eg. generate internal picture. Refer to PDP pixel
test, page 1.9.
- Checking and adjusting voltage may be performed with a DC-voltmeter
(e.g. multi meter).
Ground is connected to the chassis in the PDP, if nothing else is specied.
Measuring- and adjustment point please refer to illustrations page 1.7.
