JVC BR-6400TR: Tape Break Makes Eject Mode Impossible
Happy new year, guys,

After having winded a cassette, the above-mentioned vcr:
- normally triggers the re-winding mode;
- but because the tape broke at the very end of the cassette, the servomechanism stubbornly wants to rewind ─but the tape is broken─, preventing any command keys to stop it.
Consequently, the cassette can't be ejected.
What would you do or check first?

Thanks for your proposals
Marc
THOMSON 6380C Nem veszi be a kazettát
Sziasztok! A fenti készülék magától nem veszi be a kazit, csak ha beletolom és bekapcsolom. Ilyenkor akár le is játsza, de a kivélnél lehet, hogy nem fűzi vissza. Eléggé rendszertelenül működik. Nem találok semmit ami a kazettafészek helyzetét érzékelné. A szokásos " kék" színű üzemmód kapcsolót már rendbe tettem, de semmi javulást nem hozott. Ehhez kérném a tanácsotokat. Köszönettel : Laci
JVC VHS Fejdöntögető mechanizmus
Üdv mindenkinek! Ugyan megoldottam a keresett alkatrész-egység kiiktatásával, de azért hátha lenne valakinek bontott, nem törött példánya. A képen látható alkatrész, a JVC által alkalmazott "Dynamic Drum system" zajcsíkmentes képen keresést teszi lehetővé. A HR-S, illetve normál VHS vonalon a HR-DD típusmegjelölésű magnókban lelhető fel ez a mechanikai egység.
Is possible separate the VCR service manuals of the DVD?
I don't like that are united
If also put subgroups as VHS, Betamax, U-matic...
I like much
