| 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... | |||

About tapes: I don't know, what was original package. All the tapes came to me in a book-style cases (like cases from original license VHS tapes, or BetacamSP tape cases). I could see that both Sony and Philips tapes fails. Some Sony tapes give very good picture, some - almost only noise. The same thing with Philips tape. Today I've ordered one tape (VCC-240 Grundig) on auction, and will test it when it arrives to me :). All tapes which I have were previously recordered (old German TV channels: RTLPlus, ZDF, TV3 and others, I'll post their idents, ads and news from them on YouTube later). I'll post photos of VCR and tapes later. The idea of using new VHS tape is very interesting! The only thing which I should do is to measure correct tape length... Do you know the length of VHS E-180 and E-240 tapes? Tape path looks good. I've cleaned all guides with alcohol, and they shine as chromium-plated (a... | |||
