Note to our Service Information 1/97 (subject: Digi Basic colour television receivers - Eco voltage is about 5V too high) Due to repeated inquiries we would like to point out that resistor R 60202 that is to be changed from 68 k to 1 k is a lead-type version and not a SMD component.

Product Colour television receivers with chassis CUC 7303 and 7305, e.g. P 37-071, T 51-720 text, T 55-731 text
Possible complaint: Despite the modifications carried out according to our TV Service Information 9/96 the television sets switch occasionally to Standby after a prolonged time of operation. Reason: Temperature drift of the +E operating voltage by about 0.2 to 0.3V caused by Z-diode CD 61023. Consequently, IC 34015 TDA 8374 switches off with sudden black/white changes in the picture content or changing scenes. This Z-diode has been introduced later and therefore is drawn in only in the 1st Supplement to the CUC 7350 Service Manual. Cure: The position of the Z-diode is X=10, Y=150. Unsolder this diode and insert a SMD resistor 1206 1.2 1% in this place. Stores SMD resistor 1206 1.2 1%

Possible complaint: The sound disappears suddenly during the reception of a satellite programme and is audible again only when changing the programme or switching the TV off and on again. Reason: IC MSP 3400 on the SAT Module hangs up by static charges entering the Reset input of the IC. Cure: Unsolder the SMD capacitor CC 3800 from its place on the SAT Module and resolder it at the place indicated on the figure below.

Possible complaint: Mains supply switching transistor fails occasionally. Reason: Breaks may be found after a long time of use at the solder pads in the area of the mains supply stage especially at the connections of the mains supply transformer. Cure: Re-solder the connections in this area. Workshop: For reasons of operational reliability and irrespective of the fault, re-solder the 1.5 resistor R 622 and the choke L 663 (both components are in the area of the mains supply) with great care using ample tin.

Possible complaint: Audible hum or buzzing noise from the bass loudspeaker. Reason: Magnetic radiation from the deflection yoke into the loudspeaker. Cure: To reduce the radiation from the yoke exchange the bass box loudspeaker for a type with compensating coil. Workshop: Carry out when complaints are received. Stores: Loudspeaker with compensating coil, part no. 19154-031.61

ST 63-255 IDTV/LOG, ST 72-261 IDTV/LOG, Boston SE 7090 IDTV/LOG Possible complaint: TV set does not start occasionally. Reason: Cold solder connection of the wire bridge BR 129 with the earthing pad on the component side in the area of the mains supply stage. Consequently, the standby power supply does not start up reliably. Workshop: Re-solder the chassis connection in every television receiver coming in for repair using ample solder tin. Stores: None

Possible complaint: No picture. High tension is available. Reason: The transistors CT 181, CT 186, CT 191 and CT 193 failed because of high voltage sparks inside the picture tube. Cure: Replace the defective transistors and solder an additional diode 1N4148 from pin 7 of the RGB lead (to picture tube panel) to the ground pin 4 on the chassis. Connect the anode of the diode with pin 4. Workshop: Fit the additional diode when the transistors failed. Stores: Diode 1N4148

Product Correction of Service Information 9/97 Colour television receivers with Digi 6 chassis 1952, 1983, 1984 and built-in satellite receiver SER 150/SER 150 ET - e.g. Denver SE 8216/9 Ref./PIP, M 82-269/9 Reference Possible complaint: On reception of the channel Premiere via satellite the connected decoder does not operate while this station is decoded perfectly when received via a cable installation. Reason: The video crossbar IC TDA 6417 is overloaded on satellite reception. Cure: The change of the resistor CR 43209 from 1 M to 470 k as described in our Service Information 9/97does not produce the desired effect in every case.

Service Information TV 02/01 - Select the desired software under software download. - Copy the selected device software into the folder C:\GRUNDIG\Software of your PC which has been created when installing the F-Prog 1-PC software.
The downloaded packed file (*.zip) then must be unpacked by an appropriate unpacker for ZIP files (appropriate unpackers can be found, for example, under www.winzip.com). ZIP files cannot directly be loaded into the TV set! Additional hints/particularities for programming with the F-PROG 1: - Before connecting the Flash Programmer, switch the TV set off with its mains button then connect the programmer when the operating LED has gone out! - After starting programming, the operating LED first remains dark then starts flashing as soon as the Flash memory is deleted.
Below you find setting hints and explanations for various functions of the TV sets with the chassis Digi 100. 1. Power-on behaviour of the set In the Special functions menu you can select under the Power on menu item between automatic and Programme position 1. automatic: the set is switched on with the last power-on mode. For this, the last recognized programme position and operating mode (standby or normal operating mode) are stored. Note: if the set has been switched off with the mains button in standby mode, it goes again in standby mode after power on and must definitely be switched on using the remote control. Programme position 1: the set selects programme position 1 each time it is switched on. 2. Settings in the Programme table menu In this menu, further presettings can be programmed in addition to the channel setting for every programme position. Note: direct channel entry is only possible in the programme table. P+ reversion point: the reversion point is the limitation of the programme positions for programme selection using the P+ button. This reversion point is marked with an orange line in the programme table. To shift the reversion point, it is necessary to shift the programme position above or below this line according to the direction of shift.
Forced settings (forced colour standard, forced mono, fixed assignment of a multi-channel sound, RF time constant, AFC): In the Channel settings menu (menu guide: i -> Programme table -> Edit -> Change channel settings) you can carry out various forced settings. Note: it is also possible to set a forced colour standard for the AV programme positions in this menu.
