1 - Cassette mechanism alignment -- Videorecorder Grundig Video 2 x 4




Ersatzteile bestellen
  Hi,
I will try to answer in english:

If there is no sound, this may be a result of a poor picture (drop-out), because the audio module is muting the sound, if a picture error appears.

I guess, the video heads are contaminated or defect. Have you already cleaned all of the heads and all of the tape guides in the tape drive?
If yes: Is the tape transport ok? The tape must be guided smooth on all heads and guides (Erase head: the upper white guide, head drum: the lower guide bar, audio head: the upper white guide).

Are all blue seals on the allign screws still unbroken? Or has anybody already disalligned the tape path?

It may also be a result of bad cassette tapes. Some tapes, like AGFA, some PHILIPS and PDM have a bad magnetic tape, that, after more than 25 years, have lost some of the magnetic signal. And so, the V-2000 can not read the signal error-free.
Perhaps you have some other tapes for testing.

The accu is only neccessary for the clock and the tuner presets. If you dismount the accu (it will be the best, if the accu is already broken and leak, because the module may get destructed by the acid of the battery), you must set the clock each time you switch the machine on. And also all of the presets are delete...
2 - Accu defect -- Rasierer Braun 7570
Geräteart : Rasierer
Defekt : Accu defect
Hersteller : Braun
Gerätetyp : 7570
Kenntnis : Komplett vom Fach
______________________

Da meiner den Urlaub ja nicht überlebt hat und Ich eigentlich
ein neues Gehäuse gesucht hatte hab Ich ein Gehäuse mit Innenleben
in der Bucht gefunden also wollte Ich diesen nehmen.


Welche Accus sind im Braun 7570 verbaut?
Braun ist ja so nett keine Angaben mehr zu machen
weder in der Ersatzteilliste noch ist auf den
Accus ein Aufdruck drauf.

Eventuell 1,2V 1300mA die waren in meinem anderen Braun verbaut
da standen die Daten netterweise drauf

Hatte da was gelesen mit Rasierer resetten für was soll das gut sein?
Wenn gut wie geht das?

Danke ...

4 - tensions wrong -- Videorecorder   Grundig video 2000 2x4 2x8    videorecorder
Hey! It looks like we have another south-european v2000 freak around here! Greetings from the Land of València!

Don't become too obsessed with tensions: 11.8 seem quite normal for the 12 v tensions...

About the capacitors: I've just ordered a 16 € capacitometer from dealextreme... Sure it's not the best precission in the world but sure it's also worth a try, considering that it's half tje price of the last order I made to Farnell and I suspect almost all the caps I changed were ok...

Finally, about not seeing anything in the display despite having the correct tension: I'm quite sure it's the ablaufs...whatever! The one with the defective 'accu' battery! I haven't seen one without a defect, and in some of my machines it caused the display to not show anything! Remove the battery, clean the rust, restore tje PCB tracks and put a new battery! ...

Hi everybody!

This is my 3rd post thread in the forum. I started with one aglutinating my 4 (four!) non-working V2000. Now I think it's time to split in different posts, one for each machine/problem.

Stego, and/or some other experienced user, I hope you can enlight me!

I have two non-working Grundig 2x4 "Best Nr. 2000". One is grey/silver, lacks the closing door for the little buttons zone below the display and seems a bit old. The other one is black, shiny, in almost perfect looking condition, and seems newer. Here is a picture of them:

The silver, old one had all belts broken/non existant, but it would turn on and somehow respond to keys pressed sometimes. The black one also would turn on, but display just garbage in the screen and didn't do anything.

After little time, the newer machine had one of ...
6 - Videorecorder Grundig 2x8 stereo -- Videorecorder Grundig 2x8 stereo
Hello Nicola,

your wish is a little bit a problem...
The most of the modules "Ablaufsteuerung" are destroyed today because of the defective accu (1,2V 90 mAh).
The power supply ("Netzteil") usally is able to repair. Why do you need a complete power supply? Is it missing in your VCR?

Unfortunately, I don´t have a "Ablaufsteuerung" in working condition, and also no complete working power supply "Netzteil".

It will be very great luck, if you get these modules in our time. Remember, this VCR is about 25 years old, and also unused modules can have a defect now after this long time (dry capacitors).

I guess, the only way is: repairing the modules, if they are in the VCR but only not working.

Best regards,
stego ...
