Servicehinweise

Achtung: ESD-Vorschriften beachten

Vor Öffnen des Gehäuses Netzstecker ziehen.
Leitungsverlegung

Bevor Sie die Leitungen und insbesondere die Masseleitungen lösen,
muss die Leitungsverlegung zu den einzelnen Baugruppen beachtet
werden.
Nach erfolgter Reparatur ist es notwendig, die Leitungsführung wieder
in den werkseitigen Zustand zu versetzen um evtl. spätere Ausfälle
oder Störungen zu vermeiden.

Wichtige Masseverbindungen!

Beim Zusammenbau des Gerätes ist darauf zu achten, dass die
Masseverbindungen zwischen den einzelnen Platinen und dem Rah­men sowie dem Laufwerk und dem Rahmen gewährleistet sind.

Durchführen von Messungen

Bei Messungen mit dem Oszilloskop an Halbleitern sollten Sie nur
Tastköpfe mit 10:1 - Teiler verwenden. Außerdem ist zu beachten,
dass nach vorheriger Messung mit AC-Kopplung der Koppelkonden­sator des Oszilloskops aufgeladen sein kann. Durch die Entladung
über das Messobjekt können diese Bauteile beschädigt werden.

Messwerte und Oszillogramme

Bei den in den Schaltplänen und Oszillogrammen angegebenen
Messwerten handelt es sich um Näherungswerte!

Ausbauhinweise

Service Instructions

Attention: Observe the ESD safety regulations
Disconnect the mains plug before opening the set.
Wiring

Before disconnecting any leads and especially the earth connecting
leads observe the way they are routed to the individual assemblies.
On completion of the repairs the leads must be laid out as originally
fitted at the factory to avoid later failures or disturbances.

Important: Ground Connections!

When reassembling the set it is essential to observe that the ground
connections between the individual circuit boards and the frame as
well as between the Drive Mechanism and the frame are in good order.

Carrying out Measurements

When making measurements on semi-conductors with an oscillo­scope, ensure that the test probe is set to 10:1 dividing factor. Further,
please note that if the previous measurement is made on AC input, the
coupling capacitor in the oscilloscope will be charged. Discharge via
the item being checked can damage components.

Measured Values and Oscillograms

The measured values given in the circuit diagrams and oscillograms
are approximates!

Disassembly Instructions

1. DVD/CD aus defektem Laufwerk entfernen

– Rastnasen A (Fig. 1) zum Laufwerk drücken, Zentrierscheibe B

anheben und Halter C nach hinten schieben.

– Halter C (Fig. 1) anheben und DVD/CD aus defektem Laufwerk

entnehmen.

2. Hauptplatte

– Nach dem Tausch der Hauptplatte, des EEPROM´s (U10, optional)

oder des FLASH (U4) muss ein Software-Upgrade (Seite 1-4)
durchgeführt werden.

1. Opening the Tray when the Drive is Defective

– Press the locking lugs A (Fig. 1) against the drive, lift the centring

washer B then slide the holder C to the rear.

– Lift the holder C (Fig. 1) then remove the DVD/CD from the

defective drive unit.

2. Main Board

– After replacing the main board, the EEPROM (U10, option) or the

FLASH (U4), a software upgrade must be carried out (page 1-4).

Software-Upgrade

Das Software-Upgrade können Sie mit einem Internet-Browser über
das P@rtnerWeb (https://partnerweb.grundig.de) downloaden.
– Selbstentpackendes Programm z.B. "Vx_xx.exe" auf ein Laufwerk

Ihres PCs kopieren.
– Selbstentpackendes Programm "Vx_xx.exe" starten.
– Software-Upgrade-CD erstellen.

– Verwenden Sie nur eine neue beschreibbare CD-R / CD-RW

(keine gelöschte).
– CD-Name ist frei wählbar (z.B. Versionsstand und Gerät).
– Entpackte Dateien auf die CD-R / CD-RW brennen.
– Im Stammverzeichnis (oberste Ebene) der Software-Upgrade-

CD müssen folgende Dokumente enthalten sein:

aml_dd.TXT, Gdp2200.bin

Achtung: Sollte während dem Software-Upgrade eine Störung
(z.B. Stromausfall) auftreten, so sind eventuell die Geräte­funktionen und ein Neustart der Upgrade-Funktion nicht mehr
gewährleistet. In diesem Fall müssen Sie die eingebauten FLASH­ICs (U17) durch vorprogrammierte ersetzen (siehe entsprechen­de Ersatzteilliste).

– Software-Upgrade-CD einlegen und die Hinweise am Display und

am Bildschirm des Fernsehgerätes beachten.

– Initialisierung des Gerätes durchführen.

Gewährleistung

Wir weisen ausdrücklich darauf hin, dass nur von GRUNDIG freigege­bene System-Software zulässig ist. Wurde als Fehlerursache festge­stellt, dass eine aus nicht legitimierten Quellen gleich welcher Herkunft
stammende oder eine veränderte System-Software in die Geräte
geladen wurde, so ist dies ein Fremdeingriff. Ein Fremdeingriff führt
zum Erlöschen jeglicher Gewährleistungsansprüche. GRUNDIG muss
daher alle aus diesen Gründen resultierenden Kostenerstattungen
generell ablehnen. Instandsetzungskosten, auch innerhalb der Gewähr­leistungszeit, gehen in diesen Fällen zu Lasten des Händlers bzw. des
Endkunden.

Software Upgrade

You can download the software upgrade from the P@rtnerWeb
(https://partnerweb.grundig.de) using an Internet browser.
– Copy a self-extracting programme, e.g. "Vx_xx.exe", on a drive of

your PC.
– Run the self-extracting programme "Vx_xx.exe".
– Creating a software upgrade CD:

– Use only a new CD-R / CD-RW (not an erased one).

– Give the CD a name of your choice (e.g. version and unit name).

– Burn the unpacked documents on the CD-R / CD-RW.

– The root directory (uppermost level) of the software upgrade CD

must contain the following documents:
aml_dd.TXT, Gdp2200.bin

Attention: if a failure should occur during the software upgrade
(e.g. a mains failure), it may happen that the units function and a
restart of the upgrade function are no longer possible. If this
should be the case, you must replace the integrated FLASH ICs
(U17) with preprogrammed ICs (see corresponding spare parts
list).

– Insert the upgrade CD (see corresponding spare parts list) and

observe the hints on the display and on the screen of the TV set.
– Carry out an initialization of the set.

Warranty / costs

We expressly point out that only operating software authorized by
GRUNDIG is allowed. If a failure is caused by an operating software
which has been downloaded from not authorized sources, indepen­dent of its origin, or a modified software, this represents an outside
interference. An outside interference leads to the expiration of any
warranty claims. For this reason, GRUNDIG is obliged to generally
refuse any payment due to such infringements. In such cases, the
repair costs are at the charge of the retailer or the final customer, even
within the period of warranty.

Software-Versionsnummer anzeigen

– Am Gerät die Tasten "STOP" und "EJECT" nacheinander drücken.
– Mit der Fernbedienung die Zahlenkombination 2812 eingeben.
– Mit den Cursor-Tasten der Fernbedienung die Software-Versions-

nummer "MICRO VERSION" bzw. "CUSTOMER VERSION" an­wählen. Dabei wird jeweils die Software-Versionsnummer ange­zeigt.

Displaying the Software Version Number

– Press one after the other the "STOP" and "EJECT" buttons on the

unit.
– Enter the number 2812 with the remote control.
– Using the cursor buttons on the remote control, select the software

version "MICRO Version" or "CUSTOMER VERSION". The respec-

tive software version number then is displayed.
