Sony Sl-S770 vcr interrupted playback and AV display issues

I'm encountering an issue with my Super Betamax player. During playback, some cassettes abruptly stop playing at seemingly random points, accompanied by a sound similar to the one made when a tape reaches its end. This interruption also renders the rewind and forward buttons unresponsive. However, it does not impede the manual forwarding or rewinding of the cassette. The only solution seems to be ejecting the cassette and reinserting it. Occasionally, even this workaround fails, allowing only two seconds of playback before the problem recurs.

I sought guidance from the Mister Betamax troubleshooting page, which indicated that the tape safety device might be the root cause. I received additional advice suggesting that the issue could stem from one of the sensors within the VCR, possibly due to oxidized contacts causing intermittent operation. It was recommended to resolve this by carefully cleaning the contacts on the sensor switch responsible for detecting loaded tapes or the sensor that detects if the tape is "record-protected." Another suggestion was to monitor the output of these switches using an oscilloscope or voltmeter to determine if they are indeed the source of the problem.

I'm eager to hear if anyone has additional advice or personal experiences to share regarding this issue.

Additionally, I'm facing an AV cable problem where the yellow AV cable fails to display any video. While it used to work correctly, the AV audio cable still functions properly. As a temporary workaround, I've been using a coaxial cable and routing it through another VCR to utilize its AV output. However, I'm interested in exploring potential solutions to fix the issue with the yellow AV cable, if possible. Any insights or suggestions would be greatly appreciated.

Kellemes Karácsonyt Mester Urak! Most egy fent nevezett Videomagnó javításához kérnék segítséget, ötletet. A szalagvezető babákat -és egyéb mechanikai részeket- mozgató műanyag alkatrész egy helyen szétrepedt, a babákat nem tartja fixen, a mechanika összekuszálódik fűzés közben. Keresem tehát a mellékelt képen lévő alkatrészt! Egyenlőre nem leltem rá sehol. (két SONY gépet is szétszedtem, mindkettő SLV-típusú hifi gép, a háromban egyetlen egymásra hasonlító alkatrész sincs) Esetleg valakinek, esetleg valami beszerzési forrás? Köszönöm, előre is! Tibor

Sziasztok! A fent nevezett videóval lenne gondom. Mégpedig az, hogy időszakosan nem veszi be a kazettát ill. nem is adja ki(ha véletlen bevette). A mechanika mozgató motorral sorosan van egy 33 ohm os ellenállat az tűzforró de annyira hogy körülötte már minden feketedik. A mechanikát tisztítottam, elvileg nem is szorul, viszont ha megmozdítom a motortengelyt akkor működik. Mi lehet a gondja? Segítségeteket köszönöm. Krisz
