DIAGRAMFORKLARING

På diagrammerne er der angivet typenumre på transistorer og IC'er. Hvis positionsnummeret er efterfulgt af en stjerne, skal reservedelsnummeret altid benyttes, da denne komponent er specielt udvalgt, f.eks. TR102*.

Komponenttryk og koordinatsystem

PCB-tegningerne over de største printplader indeholder et komponenttryk og et koordinatsystem. På diagrammerne er enhver komponent forsynet med et koordinatnummer. Dette fortæller i hvilket koordinat på PCB-tegningen, komponenten er placeret. Koordinatnumrene er angivet med mindre skrifttype end positionsnumrene.

Styrekredsløb

I visse styrekredsløb er den aktive tilstand angivet med en funktionsangivelse. Denne kan eksempelvis være ST.BY. = »low« i stand-by-stilling eller ST.BY. = »high« i stand-by-stilling.

Ledningsforbindelser

Ledningsforbindelserne på diagrammerne er samlet i »bundter«. De enkelte ledninger er forsynet med en af følgende koder:

INTERN FORBINDELSE PÅ EN DIAGRAMSIDE

Interne forbindelser på en diagramside angives med et tal. Knækket på ledningen viser, i hvilken retning, den anden ende af ledningen findes.

FORBINDELSE TIL EN ANDEN DIAGRAMSIDE

Forbindelsen til en anden diagramside angives med et tal samt et bogstav for det diagram, forbindelsen går til.

Forsyningsspændinger

Alle forsyningsspændinger i diagrammerne er angivet med en pil og en spændingsangivelse.

Eksempel:

Ved siden af spændingsangivelsen står der f.eks. 7 CON. Dette betyder, at den pågældende forsyningsspænding går til 7 steder på den pågældende diagramside (7 CON. = 7 connections).

EXPLANATION OF DIAGRAM

Type numbers of transistors and ICs are indicated on the diagrams.

If the position number is followed by an asterisk the spare part number must always be used because the component in question has been specially selected, e.g. TR102*.

Component print and coordinate system

The PCB drawings of the largest printed circuit boards include a component print and a coordinate system.

On the diagrams every component has a coordinate number. This indicates in which coordinate on the PCB drawing the component is situated. The coordinate numbers are written in smaller print types than the position numbers.

Control Circuit

In certain control circuits the active mode is indicated by a function term. This may be e.g. ST.BY. = low in the stand-by mode or ST.BY. = high in the stand-by mode.

Wiring Connections

The wiring connections on the diagrams are assembled in 'bundles'. The individual wires are provided with one of the following codes:

INTERNAL CONNECTION ON ONE DIAGRAM PAGE

Internal connections on a diagram page are indicated by a number. The bend of the wire indicates in which direction the other end of the wire is found.

CONNECTION TO ANOTHER DIAGRAM PAGE

DIAGRAM	С
\| A32 /	\| A3

A connection to another diagram page is indicated by a number as well as by a letter of the diagram to which the connection leads.

Supply Voltages

All supply voltages in the diagrams are indicated by an arrow and a voltage indication.

Example:

"7 CON." This means that the supply voltage in question goes to 7 different places on the diagram page in question (7 CON = 7 connections).

Page 7

SYMBOL FOR SIKKERHEDSKOMPONENTER

Ved udskiftning af komponenter med dette symbol skal der anvendes komponenter med samme reservedelsnummer. Den nye komponent skal monteres på samme måde som den udskiftede.

MÅLEBETINGELSER

Alle DC-spændinger er målt i forhold til stel med et voltmeter med en indgangsmodstand på 10 Mohm.

DC-spændingerne og oscillogrammerne er målt i TV-mode med »BRILLIANCE« niveau 20, »CONTRAST« niveau 24 og »COLOUR« niveau 40.

DC-spændingerne er opgivet i volt (V), f.eks. 0,7 V.

Alle oscillogrammer og AC-spændinger er målt i forhold til stel med et oscilloskop eller et voltmeter med en indgangsmodstand på 1 Mohm.

AC-spændingerne er opgivet i millivolt (mV), f.eks. 660 mV.

SYMBOL OF SAFETY COMPONENTS

When replacing components with this symbol, components with identical part numbers must be used. The new component must be mounted in the same way as the one replaced.

MEASURING CONDITIONS

All DC voltages have been measured in relation to ground with a voltmeter with an input resistance of 10 Mohms.

The DC voltages and oscillogrammes have been measured in the TV mode with "BRILLIANCE" level 20, "CONTRAST" level 24 and "COLOUR" level 40.

The DC voltages are stated in volts (V), e.g. 0.7 V.

All oscillograms and AC voltages have been measured in relation to ground with an oscilloscope or a voltmeter with an input resistance of 1 Mohm.

AC voltages are stated in millivolts (mV), e.g. 660 mV.

Når PAL/SECAM dekoderen PCB40 serviceres, kan lydmodulet PCB20 fjernes.

Servicing PAL/SECAM decoder PCB40

When servicing the PAL/SECAM decoder PCB40, the sound module PCB20 can be removed.

Desuden kan tekstmodulet PCB07 eller OSD-modulet PCB14 fiernes

Apparatet viser nu billede, men der er ingen lyd, teletekst eller display på skærmen. Pil i øverste højre hjørne lyser.

Båndkabel mellem PCB40 og PCB02

Det sekspolede båndkabel mellem PCB40 og PCB02 må ikke monteres før 30 sekunder efter, apparatet er slukket.

Det skyldes, at RGB-udgangen har stelforbindelse gennem det sekspolede båndkabel.

Fokusledning

Indstråling fra fokusledningen kan hindre datakommunikationen på PCB12. Derfor må fokusledningen ikke komme i nærheden af PCB12, og ved samling af apparatet bør fokusledningen monteres som vist på tegningen.

The text module PCB07 or the OSD-module can also be removed. A picture can now be displayed on the screen, but there is no sound, teletext or display on the screen.

An arrow in the upper righthand corner lights.

Ribbon cable between PCB40 and PCB02

The 6-pin ribbon cable between PCB40 and PCB02 must not be mounted until 30 seconds after the set has been switched off. This precaution is necessary because the RGB output is connected to ground via the 6-pin cable.

Focus wire

Interference from the focus wire can impede the data communication on PCB12. Consequently, the focus wire must be kept away from PCB12, and when assembling the set the focus wire should be mounted as shown on the drawing.

ISOLATIONSTEST

Ethvert apparat skal isolationstestes, efter at det har været adskilt. Testen udføres, når apparatet er samlet igen og er klar til udlevering til kunden.

Der må ikke forekomme overslag under testen!

Isolationstesten udføres på følgende måde:

De to stikben på netstikket kortsluttes og tilsluttes den ene af terminalerne på isolationstesteren. Den anden terminal tilsluttes stelbenet i en af højttalerstikdåserne.

INSULATION TEST

Each set must be insulation tested after having been dismantled. Make the test when the set has been reassembled and is ready to be returned to the customer.

Flashovers must not occur during the testing procedure!

Make the insulation test as follows:

Short-circuit the two pins of the mains plug and connect them to one of the terminals of the insulation tester. Connect the other terminal to the chassis pin of one of the loudspeaker sockets.

OBS!

For at undgå beskadigelser af apparatet er det vigtigt, at begge terminaler på isolationstesteren har virkelig god kontakt.

Spændingsreguleringen på isolationstesteren drejes langsomt op, indtil en spænding på 1,5-2 kV er opnået. Her skal den holdes i ét sekund, hvorefter der langsomt drejes ned for spændingen igen.

NOTE!

To avoid damaging the set it is essential that both terminals of the insulation tester have good contact.

Slowly turn the voltage control of the insulation tester until a voltage of 1.5-2 kV is obtained. Maintain that voltage for one second, then slowly turn it down again.
