Notes

Service Notes Disassembly of the Chassis Before disconnecting the chassis connecting leads, observe the way they are routed to the individual assemblies like the mains switch panel, keyboard control panel, picture tube panel, deflection unit or loudspeaker. On completion of the repairs the leads must be laid out as originally fitted at the factory to avoid later failures or disturbances. Mains Cable The TV receiver must only be operated with an original mains connecting cable with an interference suspressor choke integrated in the mains plug. This mains cable prevents interference from the mains supply and is part of the product approval. For replacement please order exclusively the mains connecting cable specified in the spare parts list. Alignment All adjustment controls not mentioned in this description are adjusted during production and must not be re-adjusted in the case of repairs. Measuring Instruments: Oscilloscope with 10:1 test probe. Colour test pattern. High resistance voltmeter. Service Mode In this mode the alignment of Geometry, Peak White Level and AGC can be carried out. To call up this mode either the remote control or TV front controls can be used. Call up Service Mode To enter the service mode depress and hold the channel change buttons, P+ and P-, on the front as the TV is switched on, and hold until a picture appears. The service menu will be at the bottom of the screen G L V H R G B A. To choose a function select menu on the remote control or simultaneously depress V+ and V- on the front of the TV, but only briefly. Adjustment of the selected function is by depressing P+ or P-. Choosing another function will automatically store the adjust-ment of the previous function. To return to normal TV mode select TV on the remote control or V+ or V- on the TV.

Notes

Safety Advice X-Ray Precautions The X-radiation developing in the sets conforms to the X-radiation Regulations (January 8 1987), issued by the Physikalisch -Technische Bundesanstalt (Federal Physiotechnical Institution). The high tension for the picture tube and thus the developing X-radiation depends on the precise adjustment of the +A power supply. After every repair of the power supply unit or the horizontal deflection stage it is imperative that the EHT for the picture tube is checked and re-adjusted if necessary. To avoid consequential damages to the chassis or the picture tube the integrated protective circuits are allowed to be put out of operation only for a short time. When replacing the picture tube use only the types specified in the spare parts list.

Viewing terrestrial or satellite stations andrecording at AV 1 or AV2

Video playback from AV 1 in programmemodeWhen switching over to a programme whileplaying back from AV 1, AV 2 or AV 3, theswitching voltage will not be identified automati-cally. The switching voltage will only be evalu-ated anew as soon as a new Low —>Highchange is recognised.The playback voltage (Low —>High) at AV 1 isautomatically identified, recording form AV 2 ispossible.

Video Playback from AV 2 in ProgrammeModeThe switching voltage (Low —> High) at AV 2 isidentified automatically, recording at AV 1 is notpossible!From AV 1, the signal selected last, satellite orterrestrial, is fed out.

Video Playback from AV 3 in ProgrammeModeThe video signal from AV 3 is identified auto-matically.Recording at AV 2 is possible. The signalselected last, satellite or terrestrial, is fed out atAV 1.

Selection of AV 1 with the Remote ControlHandsetIn programme position AV 1 no video signal isfed out from AV 1. An automatic playbackvoltage at AV 2 or AV 3 does not change theoperating mode!

Selection of AV 2 with the Remote ControlHandsetIn programme position AV 2 no video signal isfed out from AV 2. An automatic playbackvoltage at AV 1 or AV 3 does not change theoperating mode.

Selection of AV 3 with the Remote ControlHandsetAn automatic playback voltage at AV 1 or AV 2does not change the operating mode.

11: Record SettingsIn Record Mode, always the signal last viewedis fed out from AV 1.Recording and re-recording is only possible viaAV 2.
